摘要：

A nitric oxide biosensor based on the photovoltaic effect of nano titanium dioxide on hemoglobin was fabricated with high sensitivity, selectivity, as well as stability. The linear detection concentration range was 5.0 x 10(-6)-4.0 x 10(-4) M. The detection limit was 1.0 x 10(-6) M with a sensitivity of 8 nA/mu M. The possible coexisting compounds would not interfere with the nitric oxide detection.
