Dr. Somenath Roy is a Research Scientist at the Institute of Bioengineering and Nanotechnology (IBN), Singapore. He received his Ph.D. in Materials Science and Engineering from the Indian Institute of Technology (IIT), Kharagpur, India in 2004. Subsequently, he received a fellowship from the Swedish Research Council and joined the Swedish Sensor Center (S-SENCE), Linköping, Sweden as a Postdoctoral Research Fellow. From 2005-2007, he worked as a Coordinator, Research Programs at Florida International University, Miami, USA.

Dr. Roy has authored/co-authored over 40 research articles in peer-reviewed journals and conference proceedings. He has also authored two book chapters. He serves as a reviewer for multiple scientific journals including IEEE Sensors Journal, Journal of Materials Science- Materials in Engineering and Sensor Letters. In addition, he served as a referee in the National Science Foundation (NSF), USA.

Dr. Roy’s present research is focused on the fabrication of micro-/nano-scale sensor platforms for ultrasensitive detection of proteins and nucleic acids. He is also engaged in developing high-throughput microfluidic platforms for studying a variety of cellular functions. In the January 2008 issue of Nano Letters, he authored an article on the first experimental evidence of charge transport through a single DNA molecule, which continues to be actively discussed by the scientific community. In other articles published in the Journal of the American Chemical Society (2009) and in Analytical Chemistry (2010), Dr. Roy and his co-workers at IBN demonstrated that a mass-producible nanogap sensor can detect nucleic acids down to femtomolar and even sub-femtomolar level without the need for polymerase chain reaction (PCR). In the field of nanoelectronics, he contributed towards the demonstration of the localized gating effect in Y-junction single-walled carbon nanotubes (Nano Letters 2006) and more recently, direct-write fabrication of 1D FET and logic circuits on single nanowires (Nanotechnology 2010).
