Abstract
A surface-enhanced Raman scattering (SERS) method has been proposed for simultaneous detection and imaging of two biomarkers on the surface of a single human breast cancer cell (MCF-7) by self-assembly of branched DNA-gold nanoaggregates.
摘要
一种表面增强拉曼散射（SERS）方法已被提出，用于通过分支DNA-金纳米聚集体的自组装，对单个人类乳腺癌细胞（MCF-7）表面的两种生物标志物进行同时检测和成像。
