DNA-templated photo-induced silver nanowires: fabrication and use in detection of relative humidity.
A very simple and novel approach of fabricating Ag-DNA network is herein reported. The Ag-DNA network can be formed from reduction of silver ion absorbed on DNA template by sunlight. Mesh size of the Ag-DNA network and the diameter of the Ag-DNA nanowire can be controlled by adjusting the concentration of DNA and irradiation time, respectively. Furthermore, the Ag-DNA network placed onto comb-like gold electrodes can be utilized as a sensor for humidity, which presents a good response to the detection of relative humidity (RH).
