Anna Demming reports on techniques that get around the diffraction limit
Anna Demming is a freelance science journalist.
Anna was materials editor of Physics World from 2018 to 2019 and was previously editor of the website Nanotechweb. She studied nanostructures for her PhD in the context of photonics, specifically plasmonics and scanning near-field microscopy. In her spare time she runs and performs in a Bristol-based dance theatre company.
