text: Coulombic interactions can be used to assemble charged nanoparticles into
higher-order structures, but the process requires oppositely charged partners
that are similarly sized. The ability to mediate the assembly of such charged
nanoparticles using structurally simple small molecules would greatly facilitate
the fabrication of nanostructured materials and harnessing their applications
in catalysis, sensing and photonics. Here we show that small molecules with as
few as three electric charges can effectively induce attractive interactions between
oppositely charged nanoparticles in water. These interactions can guide the assembly
of charged nanoparticles into colloidal crystals of a quality previously only
thought to result from their co-crystallization with oppositely charged nanoparticles
of a similar size. Transient nanoparticle assemblies can be generated using positively
charged nanoparticles and multiply charged anions that are enzymatically hydrolysed
into mono- and/or dianions. Our findings demonstrate an approach for the facile
fabrication, manipulation and further investigation of static and dynamic nanostructured
materials in aqueous environments.

text: Aprotic alkali metal–O2 batteries face two major obstacles to their chemistry
occurring efficiently, the insulating nature of the formed alkali superoxides/peroxides
and parasitic reactions that are caused by the highly reactive singlet oxygen
(1O2). Redox mediators are recognized to be key for improving rechargeability.
However, it is unclear how they affect 1O2 formation, which hinders strategies
for their improvement. Here we clarify the mechanism of mediated peroxide and
superoxide oxidation and thus explain how redox mediators either enhance or suppress
1O2 formation. We show that charging commences with peroxide oxidation to a superoxide
intermediate and that redox potentials above ~3.5 V versus Li/Li+ drive 1O2 evolution
from superoxide oxidation, while disproportionation always generates some 1O2.
We find that 1O2 suppression requires oxidation to be faster than the generation
of 1O2 from disproportionation. Oxidation rates decrease with growing driving
force following Marcus inverted-region behaviour, establishing a region of maximum
rate.

text: Oligomeric species populated during the aggregation of the Aβ42 peptide have
been identified as potent cytotoxins linked to Alzheimer’s disease, but the fundamental
molecular pathways that control their dynamics have yet to be elucidated. By developing
a general approach that combines theory, experiment and simulation, we reveal,
in molecular detail, the mechanisms of Aβ42 oligomer dynamics during amyloid fibril
formation. Even though all mature amyloid fibrils must originate as oligomers,
we found that most Aβ42 oligomers dissociate into their monomeric precursors without
forming new fibrils. Only a minority of oligomers converts into fibrillar structures.
Moreover, the heterogeneous ensemble of oligomeric species interconverts on timescales
comparable to those of aggregation. Our results identify fundamentally new steps
that could be targeted by therapeutic interventions designed to combat protein
misfolding diseases.

text: Mapping free-energy landscapes has proved to be a powerful tool for studying
reaction mechanisms. Many complex biomolecular assembly processes, however, have
remained challenging to access using this approach, including the aggregation
of peptides and proteins into amyloid fibrils implicated in a range of disorders.
Here, we generalize the strategy used to probe free-energy landscapes in protein
folding to determine the activation energies and entropies that characterize each
of the molecular steps in the aggregation of the amyloid-β peptide (Aβ42), which
is associated with Alzheimer’s disease. Our results reveal that interactions between
monomeric Aβ42 and amyloid fibrils during fibril-dependent secondary nucleation
fundamentally reverse the thermodynamic signature of this process relative to
primary nucleation, even though both processes generate aggregates from soluble
peptides. By mapping the energetic and entropic contributions along the reaction
trajectories, we show that the catalytic efficiency of Aβ42 fibril surfaces results
from the enthalpic stabilization of adsorbing peptides in conformations amenable
to nucleation, resulting in a dramatic lowering of the activation energy for nucleation.

stimuli, in particular light, is of fundamental importance, and it contributes
to the development of applications as diverse as nanofabrication and controlled
drug delivery. However, all the systems described to date are based on nanoparticles
(NPs) that are inherently photoresponsive, which makes their preparation cumbersome
and can markedly hamper their performance. Here we describe a conceptually new
methodology to assemble NPs reversibly using light that does not require the particles
to be functionalized with light-responsive ligands. Our strategy is based on the
use of a photoswitchable medium that responds to light in such a way that it modulates
the interparticle interactions. NP assembly proceeds quantitatively and without
apparent fatigue, both in solution and in gels. Exposing the gels to light in
a spatially controlled manner allowed us to draw images that spontaneously disappeared
after a specific period of time.

text: Systems in which nanoscale components of different types can be captured and/or
released from organic scaffolds provide a fertile basis for the construction of
dynamic, exchangeable functional materials. In such heterogeneous systems, the
components interact with one another by means of programmable, noncovalent bonding
interactions. Herein, we describe polymers that capture and release functionalized
nanoparticles selectively during redox-controlled aggregation and disaggregation,
respectively. The interactions between the polymer and the NPs are mediated by
the reversible formation of polypseudorotaxanes, and give rise to architectures
ranging from short chains composed of few nanoparticles to extended networks of
nanoparticles crosslinked by the polymer. In the latter case, the polymer/nanoparticle
aggregates precipitate from solution such that the polymer acts as a selective
‘sponge’ for the capture/release of the nanoparticles of different types.
