摘要：Dry eye disease (DED) is a common disease of the tears and ocular surface. Current treatments using eye drops have limitations such as low drug bioavailability, insufficiency in addressing the inflammatory changes and limited-time mediation. There are a number of bioactive components in healthy tears that are deficient in DED.  A drug delivery system that could deliver these components in a sustained release system over time would fill a gap in the currently available treatment modalties. In this study, we explored the possibility of using protein-conjugated silica nanoparticles (SiNPs) as a drug delivery system to treat dry eye disease. Our data suggests that protein-conjugated SiNPs have the potential to be used as an ophthalmic drug delivery system for conditions such as dry eye disease. The promising degradability of the silica matrix with the diverse biological properties of the proteins would allow the expansion of its application into injectable hydrogel, therapeutic contact lenses and ocular implants.
