本文报道了一种用于甲醛检测的酶自供电生物传感器(ESPB)。该传感器以甲醛脱氢酶(FDH)/聚亚甲基蓝(PMG)/巴克纸(BP)生物阳极为传感电极,以普鲁士蓝(PB)/金纳米颗粒(Au NPs)/碳纤维纸(CFP)阴极为电致变色显示电极。甲醛作为燃料在生物阳极被FDH催化氧化,产生的电子经外电路传递至阴极,使PB发生还原并引起颜色变...

A rapid method to detect and estimate the activity of the enzyme, alcohol oxidase by the use of two chemical complexes - acetylacetone (3,5-diacetyl-1,4-dihydrolutidine) and acetylacetanilide (3,5-di-N-phenylacetyl-1,4-dihydrolutidine).

本研究开发了一种快速、灵敏的方法,用于检测并估算真菌合成醇氧化酶(alcohol oxidase, AOX)的活性。该方法利用AOX特异性氧化甲醇,生成等摩尔的甲醛(HCHO)和过氧化氢(H2O2)。一方面,甲醛与中性乙酰丙酮及铵盐溶液反应,逐渐生成黄色3,5-二乙酰-1,4-二氢吡啶(λ=420 nm;λex/em=390/470...
