Biodegradable Polymeric nano particles for ophthalmic drug delivery

Researchers at the University of Portsmouth, UK have developed a drug delivery method that could replace regular eye drops by using biodegradable polymer nanoparticles to administer medicine to the eye.

Once combined with polymer nanoparticles, drugs can then be released in a controlled manner. The medicine would only need to be applied once, making regular eye drops unnecessary. The drug's release can also be triggered by an environmental or chemical signal while polymer, being biodegradable, can be broken down naturally by the body when it is no longer needed.
