Nanotechnology is an interdisciplinary field which has brought marvels not only in solid-state device industry rather various bio-medical applications like gene sensing, DNA sequencing and bio-detection etc. owe a lot to this interdisciplinary research. It’s because of bio-nanotechnology that we are able to bring the sensitivity of current bio-sensing platforms down to the molecular level. This presentation will give you an overview of the techniques as well as the latest developments in the field of Bio-Nanotechnology. Both aspects of the presentation will be highlighted by examples of various nano-systems relevant for biomedical applications such as nanoparticle synthesis, formation of nanostructured surfaces, interaction of proteins as well as bio-membranes with drugs and insight into DNA and drug delivery systems.
