Micro-Nano Engineered Functional Materials for Biomedical and Energy Application

Abstract:

In this talk I will discuss about my research studies on effects of glycan surface density on carbohydrate-mediated binding events with proteins and pathogens using surface plasmon resonance (SPR), X-ray photoelectron spectroscopy and electrochemical analysis to develop micro array based biosensor. The use of electrochemical process for developing hybrid matrixes of conducting biopolymers and nanostructured materials for application in biosensors and high efficiency dye sensitized solar cell.  In the later part of the talk, the use of low temperature plasmas to coat on micro/nano particles with controlled carboxyl and amine functionalities for biomedical uses will be disused. The effects of physicochemical nature of metal surfaces has been identified to tailor biological properties of different types of cells (Osteoblast and Mesenchymal stem cells) and assess their use in orthopedic implants or for in vitro cell biological studies. Functional materials (artificial surfaces can be designed similar to the surface of natural killer cells) were developed by combination of electrochemical processes and low temperature plasma which had showed very good potential for selective growth of different types of cells at in-vitro conditions.
