Photoresponsive Rotaxanes Switch Lipid Bilayer Neuromorphic Behavior with Light
Advanced Electronic Materials, EarlyView.A rotaxane consisting of a macrocycle ring with two azobenzene units mechanically interlocked onto an amphiphilic axle was incorporated into droplet interface bilayers (DIBs). Photoswitching between the azobenzene configurations on the ring resulted in cycling between memristive and memcapacitive behaviors in lipid bilayers, enabling programmable ...

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 ...
