Laser printing

By exploiting the mechanism of supercavitation we are able to realize laser-induced multi-scale structure on the surface of Graphene-Oxide (GO) based polymeric matrices. The objective of this activity is twofold. From a fundamental point of view, we want to investigate the role of a multi-scale topological structure on the mechanism ruling the growth of microorganism ranging from the bacteria and fungi to human stem cells. From a more applicative perspective, the aim is to provide novel GO-based matrices with tailored topological features suitable for bio-medical application as anti-bacterial coatings or culture medium for stem cell.
