Introduction to Nanotechnology with Special Reference to Ophthalmic Delivery

Abstract

The capabilities of nanotechnology are leading to widespread use of nanomaterials in biotechnology and medicine. Nanomaterials exist in various sizes, compositions, and morphology. Due to their large numbers, classifi cation systems should be implemented for proper evaluation of the nanomaterials for effi cacy and prevention of toxicity. Many nanomaterials are being studied for potential therapeutic applications in ocular disease. Conventional treatments still possess side effects and limitations and the use of nano-biomaterials for ophthalmic drug delivery can allow for design and administration of delivery systems with targeted and sustained release capabilities. Additionally, off-target activities and toxicity can be reduced.
