A Review on Status of Nanotechnology in Pharmaceutical Sciences

摘要

The most important unit operation in pharmacy is the size reduction. Improved stability, reduced toxicity, increased bioavailability, increased rate of release and good drug formulation opportunities accomplished by size reduction. In present days, the performance of various dosage forms has been increased in nanometer size. The cargo size of a specified unit, for example nanometer is 10-9 meter. The process which occurs in nano-length size or molecular size level is referred as nanotechnology. It has shown great development in engineering, physics and electronics but pharmaceutical field and medical field needs more development. Although, it has vast application in medical field like immunology, cardiology, bioengineering, oncology, ophthalmology, cardiology etc. In pharmaceutical field, it also provides excellent materials, devices and system. The present status of nanotechnology in pharmaceutical field may be counted as development as biomarkers, biosensors, nano medicine, tissue engineering, nano-robots etc. For developing new technology, as old reaches up to the limits nanotechnology gives great opportunities.
