title: Simultaneous SERS detection and imaging of two biomarkers on the cancer cell surface by self-assembly of branched DNA-gold nanoaggregates.
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.
