Nanomaterials based optical and electrochemical biosensors

The interaction of nanotechnology and biomedical sciences opens the possibility for a wide variety of biological research topics and medical uses at the molecular and cellular level. The fundamental features of biological systems such as self-assembly, self-replication, and highly specific recognition open new routes to extend solid-state top-down fabrication nanotechnologies. For example, nanomaterials like carbon nanotube, metal nanoparticle and quantum dots contribute to improve performance of biosensors and biochips. The application of nanotechnology in biomedical sciences will provide information with unprecedented precision and sensitivity, which will not only provide much deeper understanding of biosystems but also lead to the development of new revolutionary modalities of biomolecular manufacturing, early diagnostics, medical treatment, and disease prevention beyond the cellular level to that of DNA and individual proteins, the building blocks of the life process. Nanobiotechnology surely open new reliable products in the medical healthcare and food safety and environmental protection/energy conversion system. In my talk,, nanostructure based optical biosensors and electrochemical biosensors using nanomaterilas will be focused as follows.
