Probing the influence of crosslinkers on the properties, response, and degradation of enzymatic hydrogels for electrochemical glucose biosensing through fluorescence analysis.
滴铸交联水凝胶是酶促电化学生物传感器的常用平台,但其理化性质如何影响性能、稳定性和重现性仍不清楚。本研究制备了由葡萄糖氧化酶(GOx)和支化聚乙烯亚胺(BPEI)组成的第一代法拉第生物传感器,分别采用戊二醛(GA)或乙二醇二缩水甘油醚(EGDGE)作为交联剂。结果表明,EGDGE 水凝胶的电化学响应随交联剂浓度升高而增大;而 GA ...
