Nanobiotechnology is that branch of nanotechnology that deals with biological and biochemical applications or uses. Nanobiotechnology often studies existing elements of living organisms and nature to fabricate new nano-devices. Generally, nanobiotechnology refers to the use of nanotechnology to further the goals of biotechnology. The commercial applications of nanobiotechnology in biomedical field are principally directed towards development of novel drug delivery systems, and the trend is likely to remain intact for several years to come. Biotechnology and pharmaceutical industries have and will continue to remain the largest users of nanobiotechnology.
Drug delivery, being the most crucial pharmaceutical application, is the most focused area in nanobiotechnology. Besides providing an answer to solubility issues, nanobiotechnology also offers intracellular delivery possibilities. The technology also enhances the level of skin penetration in transdermal drug delivery cases. Another particularly valuable application of nanobiotechnology is nonviral gene therapy vectors. Nanotechnology also has the capability to offer “controlled release” devices featuring autonomous operation directed by particular needs. The technology also holds the potential to develop breakthrough interface systems between physical objects and living cells to allow interaction of modern electronic devices with biological systems. Years of extensive research and development in nanobiotechnology is now beginning to create new avenues for synthesis of cutting edge nanofabricated systems and devices for treating several acute ailments. Microfabrication is widely gaining acceptance as a potential process to develop miniature biological systems.
