High aspect ratio nano patterning on continuously moving thermoplastic substrates, point of care detection of pathogens and cancers on disposable SERS activated substrate, protein dynamics simulation based on elastic network interpolation (ENI) and elastic network based normal mode analysis (EN-NMA), antifungal activities of silver ions and nanoparticles.
Nanotechnology requires the feature size in nanometer scale. Nanometer length scale exhibits extraordinary mechanical, optical, electrical, magnetic, thermal properties. In order to exploit such useful property in wide range of application areas, nano features must be cost effectively produced. Although a continuous, roll-to-roll process exist in replicating nanofeatures, it is currently limited to low aspect ratio or ultra violet light curable resins and the fidelity of the replication still needs a lot of improvements. My current research is aimed at fundamental research to provide needed knowledge for the development of continuous imprinting of high aspect ratio nano features on any types of thermoplastic polymers. Thermoplastic polymers with versatile physical and chemical properties are highly desired in numerous disposable devices for the application nanotechnology in the area of energy, healthcare, biomedical, chemical or automotive, telecommunication industry. It is anticipated that results of my current research effort will construct a scientific basis to facilitate successful transfer of this novel nanomanufacturing technology to industry.
