纳米粒子三明治型传感器的组装及其在 BRCA -1检测中的应用
Nanoparticles -fabricated Sandwich Biosensor for Single -mismatched BRCA -1 Detection
摘要
Abstract
In this study,a sandwich biosensor consisting of PMP (para -magnetic particles)/DNA /Au -NPs (gold nanoparticles)was fabricated.PMPs captured and separated target DNA while Au -NPs modified with oligonucleotide detection sequences played a role in recognition and signal production.There-fore,quantitative information concerning the target analyte was translated into a colorimetric signal,which could be easily and quantitatively measured by low -cost UV -vis spectrophotometric analysis.The results indicated that it was a very simple and economic strategy for detection of single -mismatched DNA strands.关键词
