An underlying theme of research activities in our group is the development of a process engineering toolkit that will enable the use of metal nanoparticles as building blocks for applications in the fields of sensing, energy conversion, and nanoelectronics. We have developed a scalable process for the formation of robust arrays of metal nanoparticles on any desired substrate. This has aided in the fabrication of several devices such as floating gate memory devices, flexible SERS (Surface Enhanced Raman Scattering) substrates and PEMFC (Proton Exchange Membrane Fuel Cell) catalyst layers. Currently, we are working on fabricating chemiresistive sensors and nanowire array based photoelectrodes for DSSCs. Furthermore, a room-temperature process for the synthesis of monodisperse metal nanoparticles in colloidal form was developed and patented. Based on the insights gained, we are now working on novel reactor designs for high-through-put, continuous flow synthesis of monodisperse metal nanoparticles. We have also discovered a simple process for fabricating conductive electrodes on paper using an office inkjet printer. Presently, we are working on utilising such conductive films to develop low-cost products for water filtration, medical diagnostics and ubiquitous sensing.
