Progress of nano-controlled releasing system on ophthalmologic administration

Abstract

The ophthalmic application of nanometer materials are mainly concentrated on controlled releasing systems. Due to the unique properties of nanometer materials,it has great advantages in carrying ophthalmic drugs compared with the conventional method, mainly in higher bioavailability and fewer side effects. As a result, nano-controlled releasing system has good application prospect in ophthalmology. At present, a variety of different types of nano-controlled releasing systems have been used to enhance the efficiency of the ophthalmic drugs, including nanomicelle, nanoparticles, nanosuspensions, liposomes,dendrimers, etc. In this paper, the research progress as well as the application of nano-controlled releasing system on ophthalmologic administration is reviewed.
