Color-Contact
  • Introducing the (potential) drug delivery system of the future – the self-reporting color-contact lens. Designed by a team at China Pharmaceutical University, Nanjing, it uses molecular imprinting – a technique that creates molecular cavities in a polymer structure – to offer sustained drug release.

About the Author

Phoebe Harkin

Associate Editor of The Ophthalmologist

I’ve always loved telling stories. So much so, I decided to make a job of it. I finished a Masters in Magazine Journalism and spent three years working as a creative copywriter before itchy feet sent me (back)packing. It took seven months and 13 countries, but I’m now happily settled on The Ophthalmologist, where I’m busy getting stuck into all things eyeballs.
