PhoBioS is an innovative project that aims to contribute to the expanding research on microand nano-structured biological surfaces and their practical applications in various industries. With the recent surge in interdisciplinary approaches, this project recognizes the need to widen the horizons of scientific exploration in this field. The primary objective of the COST Action "Understanding interaction light – biological surfaces: possibility for new electronic materials and devices" is to facilitate collaboration among scientists from diverse disciplines in the dynamic research field of photonic effects. That results from nano- and micro-structuring of biological surfaces, as well as their applications in bionics. Our team will ensure cross-inspiration among the participants coming from different research fields and will boost innovation in research and eventual industrial developments.
