15. NANOBIOTECHNOLOGY

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 potential uses and benefits of nanotechnology are enormous. Nano- systems in biology, the most complex and highly functional nano-scale materials and machines have been invented by nature. Proteins and nucleic acids, and other naturally occurring molecules (polymers) regulate and control biological systems with incredible precision. Many nanotechnologists are in fact drawing inspiration from biology to device new materials and devices.

Some of the innovative challenges in the field of biology are:

*        New molecular imaging techniques

*        Quantitative analytical tools

*        Physical model of the cell as a machine

*        Better ex-vivo tests and improvement in current laboratory techniques and

*        Better drug delivery systems
