Surface-enhanced Raman scattering imaging of cancer cells and tissues via sialic acid-imprinted nanotags†
Abstract
Molecularly imprinted nanoparticles were prepared as surface-enhanced Raman scattering tags for the selective imaging of cancer cells and tissues against normal cells and tissues relying on the use of sialic acid-templated imprinting to recognize cancer cells, which are over-expressed with sialic acid at the surface.
