Directing light from laser into material
A researcher directs light from a laser into material, resulting in the material creating light at twice the frequency.
Randy Heflin, a professor at Virginia Tech, and colleague Kevin Van Cott received a grant from the National Science Foundation's Nanoscale Exploratory Research (NER) initiative to explore the nanoscale world through computer simulations and a combination of optics, thin-film technology and analytical biochemistry. Heflin and Van Cott are attempting to develop new sensor approaches for detecting the presence of biological entities, such as pathogens, DNA or biological compounds in an environment or a sample.
