3/18

Introduction

Nanoscience is an emerging area with a lot of potential. Economists and scientists

have equated that technology enabled nanoscience and developments might aswell create an economy similar to the petro-economy of this generation.

Global medical market for nanotechnology applications was worth $1.7 billion in

2007 and is estimated to be nearly $9.4 billion in 2018.

Nano-fiber based adhesion is expected to play a vital role in medical field in near

future. Nano-fiber adhesion based devices are expected to play a vital role in drug

delivery, wound repair, implants etc.
