text: Temporal activation of biological processes by visible light and subsequent
return to an inactive state in the absence of light is an essential characteristic
of photoreceptor cells. Inspired by these phenomena, light-responsive materials
are very attractive due to the high spatiotemporal control of light irradiation,
with light being able to precisely orchestrate processes repeatedly over many
cycles. Herein, it is reported that light-driven proton transfer triggered by
a merocyanine-based photoacid can be used to modulate the permeability of pH-responsive
polymersomes through cyclic, temporally controlled protonation and deprotonation
of the polymersome membrane. The membranes can undergo repeated light-driven swelling–contraction
cycles without losing functional effectiveness. When applied to enzyme loaded-nanoreactors,
this membrane responsiveness is used for the reversible control of enzymatic reactions.
This combination of the merocyanine-based photoacid and pH-switchable nanoreactors
results in rapidly responding and versatile supramolecular systems successfully
used to switch enzymatic reactions ON and OFF on demand.

text: Well-defined metallic nanobowls can be prepared by extending the concept of
a protecting group to colloidal synthesis. Magnetic nanoparticles are employed
as “protecting groups” during the galvanic replacement of silver with gold. The
replacement reaction is accompanied by spontantous dissociation of the protecting
groups, leaving behind metallic nanobowls.

text: Photoresponsive gold nanoparticles dispersed in a solid/frozen matrix provide
a basis for sensors that “remember” whether the sample has ever exceeded the melting
temperature of the matrix. The operation of these sensors rests on the ability
to photoinduce metastable electric dipoles on NP surfaces – upon melting, these
dipoles drive NP aggregation, precipitation, and crosslinking. These events are
manifested by a pronounced color change.
