Smart Nanomaterials and their Applications

In general, the quest for new materials stems from manufacturing cost reduction, superior performance, power-saving and miniaturization. Further, new materials with unique properties are required to meet the new challenges of modern technologies. Among various new materials that emerged over the years, a class of magnetic nanoparticle dispersions exhibiting interesting physicochemical and optical properties under a magnetic stimulus have been at the forefront of research because of their interesting technological applications in optical devices, cation sensors, optical switching,  optical filters,  defect-detecting sensors, smart cooling devices, dynamic sealing, dye removal, biomedicine and cancer therapy.  Besides such materials have been shown to be a  wonderful model system to probe fundamental phenomena such as phase behaviour, order-disorder transition, self-assembly, weak molecular interactions(~ pico Newton) between colloidal particles at the nanoscale, subtle changes in polymer conformational changes under different environmental conditions etc.   We have been working with such materials for over two decades.  In this lecture,   I will talk about smart magnetic fluids, their interesting physical properties and applications.
