Dramatic morphological changes in liposomes induced by peptide nanofibers reversibly polymerized and depolymerized by the photoisomerization of spiropyran

Frontiers in Molecular Biosciences, 2023
Cytoskeletons such as microtubules and actin filaments are natural protein assemblies, which dynamically control cellular morphology by reversible polymerization/depolymerization.

Fundamental limitations on photoisomerization from thermodynamic resource theories [PDF]

, 2020
Small, out-of-equilibrium, and quantum systems defy simple thermodynamic expressions. Such systems are exemplified by molecular switches, which exchange heat with a bath.

Coenzyme Q10 in the eye isomerizes by sunlight irradiation

Scientific Reports, 2022
Photoisomerization of lipids has been well studied. As for the eyes, photoisomerization from 11-cis isomer to all-trans-retinal is well-known as the first step of the visual transduction in the photoreceptors.

Optically Induced Ferroelectric Polarization Switching in a Molecular Ferroelectric with Reversible Photoisomerization

Advanced Science, 2021
Ferroelectrics usually exhibit temperature‐triggered structural changes, which play crucial roles in controlling their physical properties. However, although light is very striking as a non‐contact, non‐destructive, and remotely controlled external ...

Controlling the LCST-Phase Transition in Azobenzene-Functionalized Poly (N-Isopropylacrlyamide) Hydrogels by Light

Gels, 2023
Poly(N-isopropylacrylamide) PNIPAAm hydrogels were modified with a new azobenzene-containing co-monomer. In this work, light responsiveness as an additional functionality, is conceptualized to induce two phase transitions in the same material, which can ...

Role of Thr82 for the unique photochemistry of TAT rhodopsin

Biophysics and Physicobiology, 2021
Marine bacterial TAT rhodopsin possesses the pKa of the retinal Schiff base, the chromophore, at neutral pH, and photoexcitation of the visible protonated state forms the isomerized 13-cis state, but reverts to the original state within 10–5 sec.

Position of rhodopsin photoisomerization on the disk surface confers variability to the rising phase of the single photon response in vertebrate rod photoreceptors.

PLoS ONE, 2020
Retinal rods function as accurate photon counters to provide for vision under very dim light. To do so, rods must generate highly amplified, reproducible responses to single photons, yet outer segment architecture and randomness in the location of ...

Controlled rotary motion of light-driven molecular motors assembled on a gold film [PDF]

, 2010
Using circular dichroism (CD) spectroscopy, we show that light-driven rotary molecular motors based on overcrowded alkenes can function in a self-assembled monolayer on semi-transparent gold films.
