| Research Abstract |
In this study, we aimed to improve the efficiency of reverse transfection, one of the economic and low cytotoxic gene introduction methods, by preparing novel stimuli-responsive polycation releasing surface. Polycation release was examined by using cysteine as stimuli. As a result, polycation was released from the surface by applying cysteine containing aqueous solution which was nontoxic to cells. Moreover, 293T cells were well adhered to the surface and surface showed any cytotoxic activities. This functional surface would be potentially useful as experimental platform for gene introduction.
