氨基化荧光碳点制备及其荧光探针构建
Preparation and evaluation of fluorescent carbon dots (CDs) and CDs based immunofluorescence probe
摘要
Abstract
Objective To fabricate an immunofluorescence probe system of carbon dots conjugated antibody based on antigen-antibody reaction principles.Methods A green one-step microwave assisted pyrolysis method was applied to preparing fluorescent carbon dots (CDs) using aminoglucose as carbon source and the obtained CDs were conjugated with antibody via EDC/NHS reactions to build CDs based fluorescent probe.Furthermore,the properties of CDs and CDs based probe system were evaluated by Fourier transform infrared (FTIR) spectra,transmission electron microscopy (TEM),UV-vis absorption and so on.Results The as-prepared CDs showed excellent fluorescence and hydrophilicity and CDs based immunofluorescence probe exhibited the capability of quick detection of E.coli O157:H7.Cinclusion Fluorescent CDs as one new emerging environment-friendly nanomaterial has great potential in biosensors.关键词
