Single GAF Domain Phytochrome Exhibits a pH‐Dependent Shunt on the Millisecond Timescale
ChemPhysChem, Volume 26, Issue 6, March 15, 2025.During their light‐induced photocycle, phytochromes can engage in a thermal reversion back to the initially excited state, denoted as a shunt. This study investigates a pH‐dependent shunt transition in the Pfr state of the All2699g1 phytochrome from Nostoc punctiforme using UV/Vis laser flash photolysis and kinetic modeling. The findings suggest a keto‐

Reversible Fluorescence Photoswitching in DNA [PDF]
The Journal of Physical Chemistry B, 2012 We describe the engineering of reversible fluorescence photoswitching in DNA with high-density substitution, and its applications in advanced fluorescence microscopy methods. High-density labeling of DNA with cyanine dyes can be achieved by polymerase chain reaction using a modified DNA polymerase that has been evolved to efficiently incorporate Cy3 ...

Physical optics characterization of a THz time domain system: UWB leaky lens antenna vs. Austin switch [PDF]
, 2010 In this work we show that a THz time domain system based on photoconductive antennas can be improved by over one order of magnitude by using the Ultra-wideband (UWB) leaky lens antenna.

Macromolecular Rapid Communications, EarlyView.The ability of photoacids to increase their acidity in response to light irradiation (excited state proton transfer, ESPT) makes them attractive building blocks for the design of stimuli‐responsive copolymers. In this contribution, we present highly biocompatible polyphotoacids based on poly(2‐oxazoline)s bearing 1‐hydroxypyrene units. Low cytotoxicity,

The photoswitchable ABAMIs for the future regulation of GWT1 in a spatiotemporal level
Smart Molecules, EarlyView.The GWT1‐targeted azobenzene‐aminopyridine derivatives (ABAMIs), sensitive to the light at wavelengths from 365 to 520 nm, are separately developed as photochromic ligands to regulate bioactivity as well as the GWT1 functions. These molecules are smart tools in photopharmacological studies, giving an innovative method for understanding functional GWT1 ...
