Bartoli presents lecture on nanophotonics

ECE Department Chair and Chandler Weaver Chair, Filbert Bartoli recently spoke at the 2013 International Semiconductor Device Research Symposium (ISDRS) in Bethesda, Maryland and is speaking at Boston University's "ECE Distinguished Lectures series in April. Bartoli's talk at ISDRS and upcoming talk at Boston University will focus on his research on Surface Plasmon Resonance (SPR) sensors.

Bartoli spoke at ISDRS on December 11 in a talk entitled "Novel Plasmonic Interferometric Biosensor Arrays for High-Performance Label-Free Biomolecular Detection." In the talk, Bartoli discussed his research on Surface Plasmon Resonance sensors, which are used in drug discovery research and to diagnose and treat medical diseases.

"They can provide information on how the cells in our body respond to potentially harmful agents as well as to helpful medicines. However, currently available instruments are big, expensive, and not portable, so they are limited to use in research laboratories or clinical laboratories." said Bartoli.

Bartoli is researching ways to miniaturize these sensors, and he is creating smaller SPR sensors. These miniaturizing these sensors will make them more accessible by everyone. Bartoli also notes that the widespread use of these sensors could be a revolutionary step towards making healthcare more accessible to millions of people and reducing healthcare costs.

"It could also make highly personalized medicine possible, in which we could 'wear' portable sensors that tell us how our own body responds to exposure by bacteria, viruses or toxins, and what medicines would be most effective for our particular condition, based on the sensory information unique to our body."

Other areas of Bartoli's research of SPR sensors include increasing the sensor array density and time resolution to provide a much more powerful instrument. This would be important for more lab based applications, such as measuring protein activity and stability, which is important in helping us understand better how bodies fight diseases and how creating new drugs can help combat diseases.

Bartoli's PhD student, Beibei Zeng, also presented a contributed talk at the "Ultrathin Nanopatterned Metal Films for Highly Transmissive Plasmonic Subtractive Color Filters" at ISDRS on December 12.

Bartoli's upcoming talk at Boston University is to be entitled "Interferometric Plasmonic Biosensor Arrays for High-Performance Label-Free Biomolecular Detection, and will also focus on SPR sensors and his research regarding the miniaturizing of the sensors and increasing sensor density array.

Over the course of Bartoli's career, his research publications have include over 320 technical papers and 19 patents. This includes The Journal of Applied Physics paper "Polymeric photovoltaics with various metallic plasmonic nanostructures," written by Beibei Zeng, Qiaoqiang Gan, Zakya H. Kafafi, Filbert J. Bartoli, J, which was one of the most-accessed articles in that journal during the period July-October 2013.

Bartoli has been at Lehigh University since 2005 and previously served as the Program Director in the Division of Electrical and Communications Systems at the National Science Foundation. Bartoli's current research interests include nanophotonics and plasmonics for biosensors, solar cells, and slow light applications.
