Optical control of PIEZO1 channels

Nature Communications, 2023
PIEZO proteins are large, mechanically-activated trimeric ion channels. Here the authors report a light-gated mouse PIEZO1 channel, mOP1, whereby an azobenzene-based photoswitch covalently localised at the extracellular apex of a transmembrane helix ...

Transforming Commercial Polymers into Tough yet Switchable Adhesives by Trident Photoswitch Molecule Doping: Break Adhesion‐Switchability Paradox

Advances in Materials
Here, a trident molecule doping strategy is introduced to overcome both cohesion‐adhesion trade‐off and adhesion‐switchability conflict, transforming commercial polymers into tough yet photo‐switchable adhesives.

Rotational Periodicity Display of the Tunable Wettability Pattern in a Photoswitch Based on a Response Bilayer Photonic Crystal.

ACS Applied Materials and Interfaces, 2020
Although the forward diffraction of the 3D photonic crystal is easily applied to photoswitch, backward diffraction rainbows are rarely reported. The first rotational photoswitch based on a bilayer 3D photonic crystal with backward diffractions similar to

Charge-transfer dynamics in azobenzene alkanethiolate self-assembled monolayers on gold [PDF]

, 2016
We have studied the charge transfer dynamics in azobenzene-functionalized alkanethiolate self-assembled monolayers. We compare the core-hole clock technique, i.e., resonant vs. non-resonant contributions in the azobenzene autoionization of the C1s-pi∗

Ultrafast electronic relaxation pathways of the molecular photoswitch quadricyclane

Nature Chemistry
The light-induced ultrafast switching between molecular isomers norbornadiene and quadricyclane can reversibly store and release a substantial amount of chemical energy.

Highly Efficient Photoswitch in Diarylethene-Based Molecular Junctions.

Journal of the American Chemical Society, 2020
Thin layers of diarylethene oligomers (oligo(DAE)) were deposited by electrochemical reduction of a diazonium salt on glassy carbon and gold electrodes. The layers were fully characterized using electrochemistry, XPS, and AFM, and switching between open ...

Photoswitchable precision glycooligomers and their lectin binding

Beilstein Journal of Organic Chemistry, 2014
The synthesis of photoswitchable glycooligomers is presented by applying solid-phase polymer synthesis and functional building blocks. The obtained glycoligands are monodisperse and present azobenzene moieties as well as sugar ligands at defined ...

Azobenzene Photoswitch for Isomerization‐Dependent Cancer Therapy via Azo‐Combretastatin A4 and Phototrexate

Photochemistry and Photobiology, 2020
The adverse effects of chemotherapeutic drugs to healthy organs/cells greatly limit their clinical efficacy and patient compliance. The unique behavior of azobenzene photoswitch offers a remarkable tool to address the side effects of chemotherapeutic ...

Photoreversible stretching of a BAPTA chelator marshalling Ca2+-binding in aqueous media

Beilstein Journal of Organic Chemistry, 2019
Free calcium ion concentration is known to govern numerous biological processes and indeed calcium acts as an important biological secondary messenger for muscle contraction, neurotransmitter release, ion-channel gating, and exocytosis.
