柠檬酸被认为是前列腺癌早期检测的重要生物标志物。本文基于半胱氨酸包覆金纳米簇(Cys-AuNCs)的高效催化特性,建立了一种用于柠檬酸光学检测的新型比色传感系统。Cys-AuNCs具有内在过氧化物酶模拟活性,在过氧化氢(H2O2)存在下可高效催化3,3′,5,5′-四甲基联苯胺(TMB)氧化,生成在650 nm处有最大吸收的蓝色产物...

肌酸(sarcosine)是甘氨酸甲基化形成的氨基酸,在血浆和尿液中浓度升高可见于肌酸血症及前列腺癌等疾病。本研究制备了不同表面修饰的超顺磁性氧化铁纳米粒子(SPIONs),并用壳聚糖(CS)和肌酸氧化酶(SOX)进行修饰,未修饰粒子作为对照。动态光散射测得SPIONs/Au/NPs、SPIONs/Au/CS/NPs和SPIONs/...
