Development and analytical application of a glucose biosensor based on glucose oxidase/O-(2-hydroxyl)propyl-3-trimethylammonium chitosan chloride nanoparticle-immobilized onion inner epidermis.

本文报道了一种基于葡萄糖氧化酶（GOx）/O-(2-羟基)丙基-3-三甲基铵壳聚盐酸纳米颗粒（O-HTCC NP）固定化洋葱内表皮和溶解氧（O2）传感器的葡萄糖生物传感器。该传感器利用GOx催化葡萄糖氧化并消耗溶解氧，通过监测O2水平下降来定量葡萄糖。传感器对葡萄糖在0.0–0.60 mM范围内呈线性响应，检出限为50 μM（S/N...
