文摘
In the last years due to porous silicon (PS) biocompatible properties, PS layers were investigated as support for cell adhesion, as matrix for drug delivery, or for bio (optical) sensors. In this paper we have investigated different types of surface modification of nanoporous silicon in order to be used as support for immobilization of DNA molecules. Good results were obtained by DNA immobilization on Au/PS layer.
