Phaneuf Group Research Selected for VJBOA paper produced by the research group of MSE Associate Professor Raymond Phaneuf has been selected for inclusion in the Virtual Journal for Biomedical Optics (VJBO). The journal, published by the Optical Society of America (OSA), is a compilation of articles recently published in OSA's various peer-reviewed journals, plus content published in the Society for Applied Spectroscopy's Applied Spectroscopy journal. The selected articles are considered to represent cutting-edge and state-of-the-art research in optics.
The paper, "Enhanced fluorescence and near-field intensity for Ag nanowire/nanocolumn arrays: evidence for the role of surface plasmon standing waves," originally published in Optics Express (Vol. 16, Issue 22, pp.18417-18425 ), presents new insight into the mechanism for nanoparticle enhancement of fluorescence. Phaneuf's group found that for nanowires or columns of the right dimensions it is possible to set up standing waves consisting of counter-propagating surface plasmons. The resulting fields at nearby fluorescent molecules are greatly enhanced over that for the incident light, creating a much larger fluorescent intensity. This knowledge should help in the design of highly efficient biomolecular sensors, with applications in medical screening and anti-bioterrorism technology.
Phaneuf's co-authors are his former advisee, Sherman Guo (Ph.D. '08); postdoctoral research associate Julia J. Heetderks; and former postdoctoral research associate Hung-Chih Kan, who is currently an associate professor at the National Chung Cheng University, Taiwan, and part time visiting faculty in MSE.
