以聚L-酪氨酸膜为载体,固载DNA和辣根过氧化物酶(HRP)制备过氧化氢生物传感器。该传感器对H2O2表现出良好的催化还原特性,具有灵敏度高,稳定性好且易于制作等特点。其线性响应范围为:2.0×10-6~1.1×10-2mol/L,检出限为8.0×10-7mol/L(S/N=3)。
Hydrogen peroxide biosensors were prepared by immobilizing DNA and horseradish peroxidase (HRP) on poly-L-tyrosine membrane. The H2O2 sensor shows good catalytic reduction characteristics, with high sensitivity, good stability and easy to make and so on. The linear response range was 2.0 × 10-6 ~ 1.1 × 10-2mol / L, the detection limit was 8.0 × 10-7mol / L (S / N = 3).
