text: Photoswitchable molecules are employed for many applications, from the development
of active materials to the design of stimuli-responsive molecular systems and
light-powered molecular machines. To fully exploit their potential, we must learn
ways to control the mechanism and kinetics of their photoinduced isomerization.
One possible strategy involves confinement of photoresponsive switches such as
azobenzenes or spiropyrans within crowded molecular environments, which may allow
control over their light-induced conversion. However, the molecular factors that
influence and control the switching process under realistic conditions and within
dynamic molecular regimes often remain difficult to ascertain. As a case study,
here we have employed molecular models to probe the isomerization of azobenzene
guests within a Pd(II)-based coordination cage host in water. Atomistic molecular
dynamics and metadynamics simulations allow us to characterize the flexibility
of the cage in the solvent, the (rare) guest encapsulation and release events,
and the relative probability/kinetics of light-induced isomerization of azobenzene
analogues in these host–guest systems. In this way, we can reconstruct the mechanism
of azobenzene switching inside the cage cavity and explore key molecular factors
that may control this event. We obtain a molecular-level insight on the effects
of crowding and host–guest interactions on azobenzene isomerization. The detailed
picture elucidated by this study may enable the rational design of photoswitchable
systems whose reactivity can be controlled via host–guest interactions.

text: Aromatic residues are located at structurally important sites of many proteins.
Probing their interactions and dynamics can provide important functional insight
but is challenging in large proteins. Here, we introduce approaches to characterize
dynamics of phenylalanine residues using 1H-detected fast magic-angle spinning
(MAS) NMR combined with a tailored isotope-labeling scheme. Our approach yields
isolated two-spin systems that are ideally suited for artefact-free dynamics measurements,
and allows probing motions effectively without molecular-weight limitations. The
application to the TET2 enzyme assembly of ~0.5 MDa size, the currently largest
protein assigned by MAS NMR, provides insights into motions occurring on a wide
range of time scales (ps-ms). We quantitatively probe ring flip motions, and show
the temperature dependence by MAS NMR measurements down to 100 K. Interestingly,
favorable line widths are observed down to 100 K, with potential implications
for DNP NMR. Furthermore, we report the first 13C R1ρ MAS NMR relaxation-dispersion
measurements and detect structural excursions occurring on a microsecond time
scale in the entry pore to the catalytic chamber and at a trimer interface that
was proposed as exit pore. We show that the labeling scheme with deuteration at
ca. 50 kHz MAS provides superior resolution compared to 100 kHz MAS experiments
with protonated, uniformly 13C-labeled samples.

text: NMR relaxation dispersion methods provide a holistic way to observe microsecond
time-scale protein backbone motion both in solution and in the solid state. Different
nuclei (1H and 15N) and different relaxation dispersion techniques (Bloch–McConnell
and near-rotary-resonance) give complementary information about the amplitudes
and time scales of the conformational dynamics and provide comprehensive insights
into the mechanistic details of the structural rearrangements. In this paper,
we exemplify the benefits of the combination of various solution- and solid-state
relaxation dispersion methods on a microcrystalline protein (α-spectrin SH3 domain),
for which we are able to identify and model the functionally relevant conformational
rearrangements around the ligand recognition loop occurring on multiple microsecond
time scales. The observed loop motions suggest that the SH3 domain exists in a
binding-competent conformation in dynamic equilibrium with a sterically impaired
ground-state conformation both in solution and in crystalline form. This inherent
plasticity between the interconverting macrostates is compatible with a conformational-preselection
model and provides new insights into the recognition mechanisms of SH3 domains.

text: The reversible photoisomerization of azobenzene has been utilized to construct
a plethora of systems in which optical, electronic, catalytic, and other properties
can be controlled by light. However, owing to azobenzene’s hydrophobic nature,
most of these examples have been realized only in organic solvents, and systems
operating in water are relatively scarce. Here, we show that by coadsorbing the
inherently hydrophobic azobenzenes with water-solubilizing ligands on the same
nanoparticulate platforms, it is possible to render them essentially water-soluble.
To this end, we developed a modified nanoparticle functionalization procedure
allowing us to precisely fine-tune the amount of azobenzene on the functionalized
nanoparticles. Molecular dynamics simulations helped us to identify two distinct
supramolecular architectures (depending on the length of the background ligand)
on these nanoparticles, which can explain their excellent aqueous solubilities.
Azobenzenes adsorbed on these water-soluble nanoparticles exhibit highly reversible
photoisomerization upon exposure to UV and visible light. Importantly, the mixed-monolayer
approach allowed us to systematically investigate how the background ligand affects
the switching properties of azobenzene. We found that the nature of the background
ligand has a profound effect on the kinetics of azobenzene switching. For example,
a hydroxy-terminated background ligand is capable of accelerating the back-isomerization
reaction by more than 6000-fold. These results pave the way toward the development
of novel light-responsive nanomaterials operating in aqueous media and, in the
long run, in biological environments.

text: Confining organic molecules to the surfaces of inorganic nanoparticles can
induce intermolecular interactions between them, which can affect the composition
of the mixed self-assembled monolayers obtained by co-adsorption from solution
of two different molecules. Two thiolated ligands (a dialkylviologen and a zwitterionic
sulfobetaine) that can interact with each other electrostatically were coadsorbed
onto gold nanoparticles. The nanoparticles favor a narrow range of ratios of these
two molecules that is largely independent of the molar ratio in solution. Changing
the solution molar ratio of the two ligands by a factor of 5 000 affects the on-nanoparticle
ratio of these ligands by only threefold. This behavior is reminiscent of the
formation of insoluble inorganic salts (such as AgCl), which similarly compensate
positive and negative charges upon crystallizing. Our results pave the way towards
developing well-defined hybrid organic–inorganic nanostructures.

text: Although dissipative self-assembly is ubiquitous in nature, where it gives
rise to structures and functions critical to life, examples of artificial systems
featuring this mode of self-assembly are rare. Here, we identify the presence
of ephemeral assemblies during seeded growth of gold nanoparticles. In this process,
hydrazine reduces Au(III) ions, which attach to the existing nanoparticles “seeds”.
The attachment is accompanied by a local increase in the concentration of a surfactant,
which therefore forms a bilayer on nanoparticle surfaces, inducing their assembly.
The resulting aggregates gradually disassemble as the surfactant concentration
throughout the solution equilibrates. The lifetimes of the out-of-equilibrium
aggregates depend on and can be controlled by the size of the constituent nanoparticles.
We demonstrate the utility of our out-of-equilibrium aggregates to form transient
reflective coatings on polar surfaces.

text: Solid-state NMR spectroscopy allows the characterization of the structure,
interactions and dynamics of insoluble and/or very large proteins. Sensitivity
and resolution are often major challenges for obtaining atomic-resolution information,
in particular for very large protein complexes. Here we show that the use of deuterated,
specifically CH3-labelled proteins result in significant sensitivity gains compared
to previously employed CHD2 labelling, while line widths increase only marginally.
We apply this labelling strategy to a 468 kDa-large dodecameric aminopeptidase,
TET2, and the 1.6 MDa-large 50S ribosome subunit of Thermus thermophilus.

text: Precise control of the self-assembly of selected components within complex
mixtures is a challenging goal whose realization is important for fabricating
novel nanomaterials. Herein we show that by decorating the surfaces of metallic
nanoparticles with differently substituted azobenzenes, it is possible to modulate
the wavelength of light at which the self-assembly of these nanoparticles is induced.
Exposing a mixture of two types of nanoparticles, each functionalized with a different
azobenzene, to UV or blue light induces the selective self-assembly of only one
type of nanoparticles. Irradiation with the other wavelength triggers the disassembly
of the aggregates, and the simultaneous self-assembly of nanoparticles of the
other type. By placing both types of azobenzenes on the same nanoparticles, we
created unique materials (“frustrated” nanoparticles) whose self-assembly is induced
irrespective of the wavelength of the incident light.

text: Metallic nanoparticles co-functionalised with monolayers of UV- and CO2-sensitive
ligands were prepared and shown to respond to these two types of stimuli reversibly
and in an orthogonal fashion. The composition of the coating could be tailored
to yield nanoparticles capable of aggregating exclusively when both UV and CO2
were applied at the same time, analogously to the behaviour of an AND logic gate.

text: A compound combining the features of a molecular rotor and a photoswitch was
synthesized and was shown to exist as three diastereomers, which interconvert
via a reversible cyclic reaction scheme. Each of the three diastereomers was isolated,
and by following the equilibration kinetics, activation barriers for all reactions
were calculated. The results indicate that the properties of molecular switches
depend heavily on their immediate chemical environment. The conclusions are important
in the context of designing new switchable molecules and materials.

text: We introduce a self-propelled colloidal hematite docker that can be steered
to a small particle cargo many times its size, dock, transport the cargo to a
remote location, and then release it. The self-propulsion and docking are reversible
and activated by visible light. The docker can be steered either by a weak uniform
magnetic field or by nanoscale tracks in a textured substrate. The light-activated
motion and docking originate from osmotic/phoretic particle transport in a concentration
gradient of fuel, hydrogen peroxide, induced by the photocatalytic activity of
the hematite. The docking mechanism is versatile and can be applied to various
materials and shapes. The hematite dockers are simple single-component particles
and are synthesized in bulk quantities. This system opens up new possibilities
for designing complex micrometer-size factories as well as new biomimetic systems.

text: We show that diamagnetic particles can be remotely manipulated by a magnet
by the reversible adsorption of dual-responsive, light-switchable/superparamagnetic
nanoparticles down to their surface. Adsorption occurs upon exposure to UV light,
and can be reversed thermally or by ambient light. The dynamic self-assembly of
thin films of the dual-responsive nanoparticles induces attractive interactions
between diamagnetic particles. We demonstrate that catalytic amounts of the dual-responsive
nanoparticles are sufficient to magnetically guide and deliver the diamagnetic
particles to desired locations, where they can then be released by disassembling
the dynamic layers of superparamagnetic nanoparticles with visible light.

text: A range (Au, Pt, Pd) of metal nanoparticles (MNPs) has been prepared and functionalized
with (a) redox-active stalks containing tetrathiafulvalene (TTF) units, (b) [2]pseudorotaxanes
formed between these stalks and cyclobis(paraquat-p-phenylene) (CBPQT4+) rings,
and (c) bistable [2]rotaxane molecules where the dumbbell component contains a
1,5-dioxynaphthalene (DNP) unit, as well as a TTF unit, encircled by a CBPQT4+
ring. It transpires that the molecules present in (a) and (c) and the supermolecules
described in (b) retain their switching characteristics, previously observed in
solution, when they are immobilized onto MNPs. Moreover, their oxidation potentials
depend on the fraction, χ, of the molecules or supermolecules on the surface of
the nanoparticles. A variation in χ affects the oxidation potentials of the TTF
units to the extent that switching can be subjected to fine tuning as a result.
Specifically, increasing χ results in positive shifts (i) in the oxidation potentials
of the TTF unit in (a)−(c) and (ii) the reduction potentials of the CBPQT4+ rings
in (c). These shifts can be attributed to an increase in the electrostatic potential
surrounding the MNPs. Both the magnitude and the direction of these shifts are
reproduced by a model, based on the Poisson−Boltzmann equation coupled with charge-regulating
boundary conditions. Furthermore, the kinetics of relaxation from the metastable
state coconformation (MSCC) to the ground-state coconformation (GSCC) of the bistable
[2]rotaxane molecules also depends on χ, as well as on the nanoparticle diameter.
Increasing either of these parameters accelerates the rate of relaxation from
the MSCC to the GSCC. This rate is a function of (i) the activation energy for
the relaxation process associated with the bistable [2]rotaxane molecules in solution
and (ii) the electrostatic potential surrounding the MNPs. The electrostatic potential
depends on (i) the diameter of the MNPs, (ii) the amount of the bistable [2]rotaxane
molecules on the surface of the MNPs, and (iii) the equilibrium distribution of
the CBPQT4+ rings between the DNP and TTF recognition sites in the GSCC. This
electrostatic potential has also been quantified using the Poisson−Boltzmann equation,
leading to faithful estimates of the rate constants.

text: Hydrogen bonds are ubiquitous interactions in proteins, and are important
for their folding and functionality. Scalar coupling constants across hydrogen
bonds in the protein backbone, some as small as 0.5 Hz, can be directly measured
in the solid state by NMR spectroscopy (see figure). The nuclei on both sides
of the hydrogen bond can be identified and the size of the coupling constant can
be measured accurately.

text: Side-chain poly[2]catenanes at the click of a switch! A bistable side-chain
poly[2]catenane has been synthesized and found to form hierarchical self-assembled
hollow superstructures of nanoscale dimensions in solution. Molecular electromechanical
switching (see picture) of the material is demonstrated, and the ground-state
equilibrium thermodynamics and switching kinetics are examined as the initial
steps towards processible molecular-based electronic devices and nanoelectromechanical
systems.

text: Following unidirectional biophysical events such as the folding of proteins
or the equilibration of binding interactions, requires experimental methods that
yield information at both atomic-level resolution and at high repetition rates.
Toward this end a number of different approaches enabling the rapid acquisition
of 2D NMR spectra have been recently introduced, including spatially encoded “ultrafast”
2D NMR spectroscopy and SOFAST HMQC NMR. Whereas the former accelerates acquisitions
by reducing the number of scans that are necessary for completing arbitrary 2D
NMR experiments, the latter operates by reducing the delay between consecutive
scans while preserving sensitivity. Given the complementarities between these
two approaches it seems natural to combine them into a single tool, enabling the
acquisition of full 2D protein NMR spectra at high repetition rates. We demonstrate
here this capability with the introduction of “ultraSOFAST” HMQC NMR, a spatially
encoded and relaxation-optimized approach that can provide 2D protein correlation
spectra at ∼1 s repetition rates for samples in the ∼2 mM concentration range.
The principles, relative advantages, and current limitations of this new approach
are discussed, and its application is exemplified with a study of the fast hydrogen−deuterium
exchange characterizing amide sites in Ubiquitin.
