Noninvasive monitoring of bilirubin photoisomer excretion during phototherapy
Scientific Reports, 2022 Lumirubin is the most prevalently excreted hydrophilic bilirubin photoisomer in phototherapy for neonatal jaundice caused by excess hydrophobic unconjugated bilirubin (ZZ-bilirubin).

Electrostatic control of photoisomerization pathways in proteins
Science, 2020 Electrostatics guide chromophore twist Photoisomerization—the twisting of bonds in a molecule in response to absorption of light—is exploited in biology to sense light and can influence the photophysical properties of fluorescent proteins used in imaging

Reversible Actuation via Photoisomerization-Induced Melting of a Semicrystalline Poly(Azobenzene).
ACS Macro Letters, 2020 Photoisomerization of azobenzene in polymer matrices is a powerful method to convert photon energy into mechanical work. While most previous studies have focused on incorporating azobenzene within amorphous or liquid crystalline materials, the limited ...

Manipulating azobenzene photoisomerization through strong light–molecule coupling [PDF]
Nature Communications, 2018 The formation of hybrid light–molecule states (polaritons) offers a new strategy to manipulate the photochemistry of molecules. To fully exploit its potential, one needs to build a toolbox of polaritonic phenomenologies that supplement those of standard ...

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 ...

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 ...

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.

Blue light regenerates functional visual pigments in mammals through a retinyl-phospholipid intermediate. [PDF]
, 2017 The light absorbing chromophore in opsin visual pigments is the protonated Schiff base of 11-cis-retinaldehyde (11cRAL). Absorption of a photon isomerizes 11cRAL to all-trans-retinaldehyde (atRAL), briefly activating the pigment before it dissociates ...
