Amplifying the Sensitivity of Raman Spectroscopy Using Carbon Nanotubes Probes

Using carbon nanotubes, a research team led by Professor Hyung Gyu Park in collaboration with Dr. Tiziana Bond has developed a sensor that greatly amplifies the sensitivity of commonly used but typically weak vibrational spectroscopic methods, such as Raman spectroscopy. This type of sensor makes it possible to detect molecules present in the tiniest of concentrations.

Raman Spectroscopy: Highly Sensitive Probes for Cancer Diagnostics

Surface-enhanced Raman spectroscopy (SERS) is a powerful tool for detecting and analyzing chemicals. The technology has recently emerged as a non-invasive tool for imaging cells and detecting cancer. Compared with fluorescence microscopy and other conventional fluorescence-based imaging techniques, SERS does not suffer from the problem of photobleaching-degradation of the fluorescence of the probes used as a result of repeated light exposure. more
