Chemical binding of molecular-imprinted polymer to biotinilated antibody: Utilization of molecular imprinting polymer as intelligent synthetic biomaterials toward recognition of carcinoma embryonic antigen in human plasma sample.

Journal of molecular recognition : JMR 2021 Abdollahiyan P, Mohammadzadeh A, Hasanzadeh M

本研究报道了一种基于分子印迹聚合物(MIP)的电化学生物传感器,用于识别人血浆中的癌胚抗原(CEA)。作者以金电极为工作电极,先用半胱胺和戊二醛进行交联预处理,再在 CEA 模板存在与不存在条件下电聚合甲苯胺蓝,分别制备 MIP 和非印迹聚合物(NIP)修饰电极。CEA 被包埋于印迹聚合物形成的特异性空腔中,随后通过洗脱去除模板,保...

Development of a reliable bioanalytical method based on prostate specific antigen trapping on the cavity of molecular imprinted polymer towards sensing of PSA using binding affinity of PSA-MIP receptor: A novel biosensor.
