Recent years has witnessed the inroad of nanotechnology on healthcare heralding new era aptly labeled ‘nanomedicine’. This symposium will cover broad areas bridging nanomaterials and medical science : Carbon-based nanomaterials, Soft Nanostructured biomaterials – Proteins, Enzymes, DNA, RNA, Viruses.
Novel properties that differentiate nanomaterials from bulk materials generally develop at a length scale of ~10 nm. However, the size at which materials display different properties to the bulk material is material dependent. From the biological point of view, nanomaterials match the typical size of naturally occurring functional units or components of living organisms and, for this reason, enable more effective interaction with biological systems. The application of nano-materials in medicine and enhancing quality of life can be understood from state of the art knowledge on nanoscale features of biological systems in order to learn how to design nano devices for biomedical uses. Nanomaterials have a relatively larger surface area and, therefore, are more chemically reactive. In addition, the nano-scale has a marked effect on the strength and electrical properties as the quantum effects dominate the behavior of materials with respect to their optical, electrical, and magnetic properties. Basically nanomaterials fall into three categories: one-, two-, and three-dimensions.
Nanomaterials have been proposed as key components in biosensing, imaging and drug delivery schemes since they confer distinctive advantages over conventional approaches, e.g. sensitivity. In particular, the characteristic electronic and optical properties of carbon based-materials are potentially significant in diagnostic sensing and imaging in vitro and in vivo. The unique chemical and physical properties of carbon nannomaterials offer opportunities to functionalize and append biomaterials in developing protein transducers, therapeutic drug delivery vehicles, gene delivery systems, and microbial diagnostic (bacteria and viruses) for use in both in vitro and in vivo modes that can be used for health care.
