Feedback-Control of Photoresponsive Fluid Interfaces

, 2017
Photoresponsive surfactants provide a unique microfluidic driving mechanism. Since their molecular shapes change under illumination and thereby affect surface tension of fluid interfaces, Marangoni flow along the interface occurs.

Solution phase and surface photoisomerization of a hydrazone switch with long thermal half-life.

Journal of the American Chemical Society, 2019
Photoswitches can be employed for various purposes, with the half-life being a crucial parameter to optimize for the desired application. The switching of a photochromic hydrazone functionalized with a C6 alkyl thiolate spacer (C6 HAT) was characterized ...

Regulation of mRNA translation by a photoriboswitch. [PDF]

, 2020
Optogenetic tools have revolutionized the study of receptor-mediated processes, but such tools are lacking for RNA-controlled systems. In particular, light-activated regulatory RNAs are needed for spatiotemporal control of gene expression.

Analysis of characteristics of paraxial vector Gaussian beams affecting the formation of microstructures in an azopolymer [PDF]

Компьютерная оптика, 2019
The paper considers paraxial Gaussian laser beams with different polarization states and their characteristics, such as the Poynting vector, gradient force, and force density, which are important for evaluating the effects of radiation on matter.

Characterization of DAG Binding to TRPC Channels by Target-Dependent cis–trans Isomerization of OptoDArG

Biomolecules, 2022
Azobenzene-based photochromic lipids are valuable probes for the analysis of ion channel–lipid interactions. Rapid photoisomerization of these molecules enables the analysis of lipid gating kinetics and provides information on lipid sensing.

Thiophenylazobenzene: An Alternative Photoisomerization Controlled by Lone‐Pair⋅⋅⋅π Interaction

Angewandte Chemie, 2019
Azoheteroarene photoswitches have attracted attention due to their unique properties. We present the stationary photochromism and ultrafast photoisomerization mechanism of thiophenylazobenzene (TphAB).
