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),
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
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
