Tweezers Catch and Analyze Particles


Kevin Robinsonon Photonics Technology News, October 2002.


Researchers at East Carolina University in Greenville, N.C., have developed a combined laser tweezers and Raman spectroscopy technique that enables them to capture and measure both transparent and nontransparent particles. The system could prove useful in industrial and scientific laboratories.


Raman Spectra from single cells


Eric Lerner on The Industrial Physicist News, Volume 8, Number 4, August/September 2002.


Raman spectroscopy is extremely useful to biochemists, with a single spectrum revealing the presence and relative concentrations of dozens of chemicals.Spectroscopy of individual cells is particularly valuable, since it would allow researchers to observe biochemical changes as they happen during the growth and division or when cells become sick or cancerous.



Optical-Trapping System Tested on Living Cells


Tyler Krupa on OSA Optics & Photonics News, Vol. 13, pp.8-9, June 2002.


Scientists at East Carolina University (Greenville, North Carolina) led by Yong-qing Li, have developed a compact laser tweezers Raman spectroscopy (LTRS) system that provides real-time spectroscopic measurements of living cells.


Raman Tweezers Probe Living Cells


Jacqueline Hewett on Optics.org, 27 February 2002


ECU group has made the first study of living cells using Raman Tweezers, a combined laser tweezers and Raman spectroscopy (LTRS) system.
