Nature paper features HORIBA Scientific LabRAM Raman microscope

Professors Wang (Georgia Institute of Technology, USA) and Tian (Xiamen University, China) and co-workers have recently reported a new SERS technique: shell-isolated nanoparticle-enhanced Raman spectroscopy (SHINERS).  In SHINERS the Raman signal amplification is provided by gold nanoparticles with an ultrathin silica or alumina shell. A monolayer of such nanoparticles is spread as ‘smart dust’ over the surface that is to be probed.  SHINERS is an extremely elegant technique, providing strong enhancement, with a SERS active material which is suitable for use with a wide range of samples.

Raman measurements reported in the paper were acquired with a HORIBA Scientific LabRAM 300 Raman microscope, and a diverse range of materials including adsorbed hydrogen species on Pt and Si, yeast cells, and whole citrus fruits were analysed using the SHINERS technique.
