Title: Light-tunable optical cell manipulation via photoactive azobenzene-containing thin film bio-substrate
(Submitted on 1 Dec 2020 (v1), last revised 28 Dec 2021 (this version, v2))
Abstract: In-vivo, real-time study of the local and collective cellular biomechanical responses requires the fine and selective manipulation of the cellular environment. One innovative pathway is the use of photoactive bio-substrates such as azobenzene-containing materials, which exhibit spectacular photomechanical properties, to optically trigger the local, mechanical stimulation of cells. Excited cells exhibit spectacular morphological modifications and area shrinkage, which are dependent on the illumination. This demonstrates the capabilities of photomechanically active substrates to study the phenomena resulting from the mechanical interaction of cells with their environment.
