Successful treatment and Control of HIV/AIDS is one of the biggest challenge of 21st century. The situation demands development of effective prevention strategies to control the pandemic of AIDS. Due to availability of an effective HIV vaccine, antiretroviral drug and nucleic acid therapeutics like siRNA have been explored for HIV prophylaxis. Nanomedicine, the structure is similar to biological structures and useful for in-vitro and in-vivo researches.  Carbon nanotubes were discovered in 1991 by Sumio lijima of NEC. Nanuotube electronic devices provide highly specific electronic sensors for detecting clinically important bimolecules like antibodies associated with human autoimmune disease and targeted delivery of drugs.
