NANOTECHNOLOGY REVIEW: LIPOSOMES, NANOTUBES & PLGA NANOPARTICLES

General awareness of Nano formulations

The very exploitation of nano scale gives wide opportunities to scientist to give out utmost to the field of technology. Medicine system have developed vast arenas so as to provide suitable opportunities for drug development in all aspects of pharmaceuticals. It must be understood that nanotechnology provides an opportunistic approach to drug development as in to produce most critical form of dosage for patient care. It is indeed a challenge for formulation scientist to develop such formulations which require utmost care during development phase and moreover challenge arrives when we talk about the stability of such products. The contemporary world of medicine is facing situations where efficacy and safety both cannot be compromised. However, stability also emerges as a critical parameter to be reckoned with for the sake of product development. Nanotechnology is able to create engineering miracles so to say, when the range of nanoscale is perhaps exploited. Nanomaterials have magnificent properties of magnetism, biochemistry, optics and mechanics. Recent advances apart from medicine in nanotechnology are energy storage and agricultural enhancement etc. The molecular scale utilized is generally less than 100 nm which is approximately one-billionth of a meter. It may be reminded to the readers that this novel field of nano system is yet to reach its climax and maturity. Various issues develop around developing such well-structured systems. Most of the techniques involved are generally under research or academic phase. Around 1960, the first generation of such products marked its opening in the world of medicines though gold nanoparticles were already discovered by Faraday around 150 years ago. The second generation of products are now emerging out with the advent of new polymers. There are many types of nano systems available having
