All throughout life, from early embryonic development through the operation and interaction of cells and tissues in the adult body up to the process of regeneration, biophysical signals, particularly mechanosensation, play a crucial role. Extracellular mechanical stimuli cause tissue regeneration, which includes processes including cell division, differentiation, migration, and ejection [1,2,3]. Age causes the body's ability to rejuvenate to decline, which negatively impacts on our lives.

The techniques for modulating or controlling mechanical stimulation of cells that are currently available frequently lack the effectiveness, dependability, reversibility, and spatial sensitivity needed for in vitro and in vivo applications. Here, we demonstrate a cutting-edge method for manipulating mechanosensitive ion channels using exogenous organic semiconductors. Materials of this class may be readily processed into a variety of forms, such as thin films, microstructured devices, or nanoparticles, and are totally biocompatible, providing the potential for in vivo use. However, their particular opto-electrical characteristics stand out the most, offering exceptional visible light responsivity as well as electron and ion conductivity.

In this study, we investigate the potential for accurate and efficient regulation of the activation of mechanosensitive ion channels using organic semiconductors, particularly conjugated polymers. We critically examine the outcomes produced by various techniques, such as microstructured devices and polymer thin films.

Our findings may pave the way for the development of cutting-edge smart materials for tissue regeneration triggered by physical stimuli.
