A feasible electrochemical biosensor for determination of glucose based on Prussian blue - Enzyme aggregates cascade catalytic system.

在碳布上构筑珊瑚状金微纳结构并电沉积普鲁士蓝(PB)，构建高灵敏过氧化氢传感器。SEM显示珊瑚状金形貌，EDS和XPS证实Au与PB成功负载。PB/Au/CC在-0.05 V下对H2O2的线性范围为0.002–13.97 mM，灵敏度为454.97 μA mM^-1 cm^-2，检出限为0.5 μM(S/N=3)。随后采用交联酶聚集...
