Abstract
A b s t r a c t: We report fabrication of fluorescent micro/nanostructure by two-photon polymerization of sartomer (SR) with doped-carbon quantum dots for attomolar dimethylarsinate(DMA) detection. Fluorescent selective detection in picomolar range (50-300pM) was achieved followed by sensor fabrication (area~100µm*100µm).
