Microneedles are used for micro-projections of drugs. Microneedles are the pathways to biological membranes which can create transport pathways of micron dimensions for sampling body fluids, such as for measuring the blood glucose levels in diabetic therapy. Microneedle drug delivery system play an important role in pharmaceutical, biotechnology and medical industries. Array and microfabrication technologies are used extensively in medicine, biotechnology and pharmaceutica research.
Microneedle drug delivery system promise pain-free delivery of both small and large molecular weight active pharmaceutical ingredients into the viable epidermis avoiding contact with nerve fibers and blood vessels present in the dermal layers. However, new developments in biotechnology, microfabrication technology, allow to demonstrate in vitro, ex vivo, and in vivo experiments, which is also paving the way for enhancement in the delivery of drugs.
