A chitosan based hydrogel has been fabricated using silver ions as crosslinking agent. Silver redox behavior in the hydrogel is suppressed due to complexation. However, hydrogen peroxide induced hydroxyl radicals could attract the glucoside bonds and consequently restore silver redox behavior. Therefore, we used this hydroxyl radical induced chitos and epolymerization mechanism as an indicator for antioxidant capacity evaluation. Therefore, we used this hydroxyl radical induced chitos and epolymerization as an indicator for antioxidant capacity evaluation. Due to the low cost, portability and avoidance of the need for electrode modification, we believe the proposed hydrogel sensing platform shows great potential for antioxidant screening applications.

已经使用银离子作为交联剂制备了基于壳聚糖的水凝胶。由于络合作用，水凝胶中的银氧化还原行为受到抑制。但是，过氧化氢诱导的羟基自由基可以吸引糖苷键，从而恢复银的氧化还原行为。因此，我们使用该羟基自由基诱导的壳聚糖和聚合机理作为抗氧化剂容量评估的指标。因此，我们使用该羟基自由基诱导的壳聚糖和聚合反应作为抗氧化剂容量评估的指标。由于成本低，便携性强和无需电极修饰，我们认为拟议的水凝胶传感平台在抗氧化剂筛选应用中显示出巨大的潜力。
