Abstract

We developed a cytometry glass chip using polymer-based saltbridge electrodes. Saltbridge electrodes were placed at lateral sides of channel to increase the sensitivity and robustness of detection. The dimension of saltbridge electrodes which are exposed to channel was 50μm by 20μm(width, height). The saltbridge electrode was formed at a specific position in a predefined shape by photo polymerization technique. UV light sensitive monomer DMAC(dially dimethyl ammonium chloride) was used for polymerization. Polymer-based saltbridge electrode enabled the DC impedance analysis of the channel for cytometry. Moreover, the lateral positioning of saltbridge electrode is easily accomplished by photo polymerization technique. We validated the detection sensitivity of developed chip using 10μm fluorescent bead.
