About me

Sagnik Basuray, PhD, completed his doctoral studies from the University of Notre Dame in the department of Chemical and Bio-Molecular Engineering in 2011, where he won the best thesis award. Since 2012, he was working as a postdoctoral fellow in the department of Electrical and Computer Engineering, University of Missouri, at the Center for Micro/Nano Systems and Nanotechnology, in the area of materials science, nanotechnology and optics.  Prior to his stint at Missouri, he was working as a Research Scientist at 454 Life Sciences, a Roche Company, building the next generation semi-conductor based sequencing platform.

At Notre Dame he worked extensively in nanofluidics, microfluidics with core competency in biomedical diagnostics to research interfacial electro-kinetic properties like dielectrophoresis. He designed robust, cost-effective Point-of-Care devices with electrochemical sensors as an alternative to real time PCR and DNA sensing. The sensor work has been licensed and developed by F Cubed LLC. and is now in clinical trials. His research was highlighted during the 2010 Michigan-Notre Dame football game at halftime as an ad to showcase the research activities at the University of Notre Dame. During his postdoctoral stint, he has developed top-down fabrication protocols (soft lithography) to fabricate hierarchical nano-ordered plasmonic/photonic structures which show extra-ordinary electro-magnetic field enhancement. These were used to investigate single biological molecules like DNA, RNA, FRET pairs and to develop multi spatial/temporal techniques (Raman, Fluorescence) from a single platform. Sagnik has always worked closely with groups from biochemistry, biology, biological engineering across many collaborative and interdisciplinary research projects.

Research

 Our research efforts are to establish a synergy between novel nanostructures, optics (plasmonics and photonics), biology and electro-kinetics (microfluidics and nanofluidics) and integrate them to develop transformative and disruptive new technologies using cost-effective tools (3D printing). This will be instrumental in the development of fundamental understanding of interfaces and surface physics arising out of the interaction of metallic/dielectric atoms with biological molecules in an energy landscape.

  • We are developing a new, cost-effective soft lithographic technique adaptable to 3D printers for microfluidic and nanofluidic architecture. Successive iterations will introduce hierarchical nano-ordered plasmonic-photonic metallic/dielectric surface topology for optical/Raman enhancement across a broad wavelength spectrum.
  • Using the new surface DNA separation technique build upon surface entropic traps and electro-kinetic phenomena like dielectrophoresis (DEP), we will sequester, transport and thereby, isolate and/or concentrate species of interest. The goal is to fabricate a passive microfluidic MEMS device to isolate, concentrate and collect sweat for downstream measurement using the chromatographic surface DNA separation for measurement of Cystic Fibrosis.
  • We are envisioning a new class of devices with liquid-liquid interfaces instead of solid-liquid interface for next generation of modular sensors (for point-of-care diagnostics) that will use interfacial phenomenon, surface energy landscape, electro-kinetics, electro-magnetic field enhancement for identification and measurement of biological molecules of interest.
