Photoinduced Fusion of Micro‐Vesicles Self‐Assembled from Azobenzene‐Containing Amphiphilic Diblock Copolymers

“…In solutions of amphiphilic molecules or polymers containing suitable chromophores, exposure to light can be used to achieve photoresponses, such as precipitation, aggregation, and self‐assembly 23–25. Recently, Azobenzene‐containing amphiphilic polymers have received considerable attention.…”

Hydrogels in Biosensing Applications

“…20 Also, cells are commonly immobilized in hydrogel matrices for various purposes. Such gels are sensitive to small changes in the environment and give the response to physical stimuli (temperature, 25 light, 26 pressure, 27 electric fields, 28 ionic strength, 29 and magnetic field 30 ), chemical stimuli (pH, 31 ions 32 ), or biological stimuli (glucose, 33 enzyme, 34 and antigen 35 ) through volume changes. As a result of recognition, volumetric change creates a new kind of sensing system instead of the classical biosensor based on the electrochemical way.…”

Phase Transitions and Pattern Formation in Chemo‐Responsive Gels and Composites

“…It is known that polymer gels exhibit two distinct phases, swollen and collapsed, with volume transitions between theses phases occurring either continuously or discontinuously in response to various external stimuli ,. While the theory of volume phase transitions in uniform gels with changes in such parameters as solvent quality, temperature,,, light intensity, or ionic strength and pH is rather well developed, the phase transitions in the samples that could no longer be considered uniform are less understood. During the phase transitions in such non‐uniform samples, the growth of one phase is enabled by adsorbing the solvent from the neighboring regions .…”
