Development of amino functionalized carbon coated magnetic nanoparticles and their application to electrochemical detection of hybridization of nucleic acids.

本研究开发氨基功能化碳包覆磁性纳米粒子（NH2-CC-MNPs）并将其用于核酸杂交的电化学检测。首先以 Fe3O4 磁性纳米粒子为核，经葡萄糖焦糖化形成碳包覆层，再用 APTES 硅烷化引入氨基，制备得到 NH2-CC-MNPs。SEM 显示其为球形，粒径约 28 nm；SEM/EDX 与 FTIR 证实碳和 APTES 成功引入；...
