Dynamic biointerfaces: new generation of cell instructive materials — •Chiara Fedele, Ravichandran H. Kollarigowda, Silvia Cavalli, and Paolo A. Netti — Center for Advanced Biomaterials for Healthcare, Istituto Italiano di Tecnologia, Neaples, Italy
Nowadays the growing interest in tissue engineering and biology for the in vitro control of cell fate has led to the design of dynamically actuable platforms through the implementation of stimuli-responsive materials in order to mimic the continuous remodeling of the extracellular matrix in living systems. Dynamic biointerfaces are conceived in order to be able to modify in a predictable spatiotemporal manner the cell-material crosstalk, overcoming the limitations of static conventional biomaterials. In our work, azobenzene-containing photosensitive polymers (e. g. polymer brushes, thin films, crosslinked free standing polymers) are designed as biomaterials to obtain patterned or reshaping substrates using photolithographic techniques or single laser beam instruments, in some cases even in presence of cells, allowing for a real-time modification of cell behavior.
