Skin microbiota monitoring by nanowire MOS sensors

In this work is illustrated the potentiality use of a Nanowire (Nw) MOS sensor array to be use as tool to monitor the human skin microbiota in order to identify quantitative and qualitative changes. Tree different blends of microorganisms grown in artificial sweat have been tested. Classical techniques, like GC-MS with SPME, have been performed as well, in order to have a multidisciplinary approach and consistent data set. The obtained results show the ability of the NW technology to discriminate between the different blends of microorganisms and to follow up the development of the growth inside the blends during the analysis. The previous results have been confirmed by GC-MS with SPME.
