From: Light-induced rolling of azobenzene polymer thin films for wrapping subcellular neuronal structures
A Generalized freestanding thin-film microdevices of 5–100 µm2 dispersed in physiological solution or cell medium at high concentrations. B Microinjection of the devices into cultures, tissues, or organs. C Devices engineered to roll can actively wrap cellular parts like neuronal processes through a wireless stimulus. For instance, materials containing azobenzene units can transform when illuminated thanks to the photoinduced isomerization of azobenzenes. D Illustrative placement and characteristics of the developed technology. Illustrations partially created with BioRender.com.
