Cell behaviour in new poly(l-lactic acid) films with crystallinity gradients
Bernardo, Vasco; Luz, Gisela; Alves, N. M.; Mano, J. F.We report a new facile method for the development of crystallinity gradients in poly(l-lactic acid) films, based on the gradual dipping of amorphous PLLA samples in a hot bath. Isothermal cold crystallization studies were performed using DSC and optical microscopy in order to find adequate conditions to generate crystallinity gradients in the PLLA films. Cellular response along PLLA samples with graded spheruli...
