Surface-enhanced Raman scattering imaging of HER2 cancer markers overexpressed in single MCF7 cells using antibody conjugated hollow gold nanospheres

Biosens Bioelectron. 2009 Mar 15;24(7):2260-3. doi: 10.1016/j.bios.2008.10.018. Epub 2008 Nov 5.

Abstract

Antibody-conjugated hollow gold nanospheres (HGNs) have been used for the SERS imaging of HER2 cancer markers overexpressed in single MCF7 cells. SERS mapping images show that HGNs have much better homogeneous scattering properties than silver nanoparticles. The results demonstrate the potential feasibility of HGNs as highly sensitive and homogeneous sensing probes for biological imaging of cancer markers in live cells.
