Abstract
Surface-mediated gene delivery has attracted more and more attentions in biomedical research and applications because of its characteristics of low toxicity and localized delivery. Herein, a novel visible-light-regulated, surface-mediated gene-delivery platform is exhibited, arising from the photoinduced surface-charge accumulation on silicon. Silicon with a pn junction is used and tested subsequently for the behavior of surface-mediated gene delivery under visible-light illumination. It is found that positive-charge accumulation under light illumination changes the surface potential and then facilitates the delivery of gene-loaded carriers. As a result, the gene-expression efficiency shows a significant improvement from 6% to 28% under a 10 min visible-light illumination. Such improvement is ascribed to the increase in surface potential caused by light illumination, which promotes both the release of gene-loaded carriers and the cellular uptake. This work suggests that silicon with photovoltaic effect could offer a new strategy for surface-mediated, gene-delivery-related biomedical research and applications.

Abstract
Surface-mediated gene delivery appears to be potential gene delivery modes for various applications. Still, controlled and smart delivery manners are required especially considering the need for gene therapy to deliver gene with selectivity. A surface that can effectively payload DNA, promote cell adhesion, and stimuli response is an important prerequisite. Here, we report a matrix metalloproteinase (MMP)-responsive surface-mediated gene delivery system by combining MMP-degradable hydrogel with a breath figure (BF) porous film. The MMP-degradable hydrogel containing plasmid DNA was loaded into the surface pores of the BF film as DNA reservoirs. The upper surface without hydrogel on the BF film served as footholds of integrin adhesions. MMP is one of the important endogenous signals in tumor-related pathologic changes, and MMP expressions in cancer cells are significantly higher than those in normal cells. Consequently, our surface-mediated gene delivery locally and rapidly released the payload DNA in response to cancer cells and transfected them. This work highlights the importance of the combination of stimuli-response and surface-mediated gene delivery to functional materials, showing good potential applications in the field of gene therapy.
