Annie Cavanagh and David McCarthy

Annie and David, from the School of Pharmacy, University of London, have been producing wonderful images together for several years. David has been a microscopist for 40 years and set up the Electron Microscope Unit at the School of Pharmacy in 1977. He has imaged numerous samples - including cell cultures, crystals, most forms of drug delivery vehicle, liposomes, polymers and carbon nanotubes - using a wide range of imaging techniques.

Annie is the multimedia unit manager at the School of Pharmacy. It is her brilliant colourisation that enhances David's black-and-white micrographs in a partnership that has won many awards. Annie says: "I think it is really important to express science for the public in an artistic fashion so that they relate to something that they think is beautiful as well as scientific." Such images can be of tremendous value to scientists, too: "When you've got a graphic and you can actually see something three-dimensionally, it makes a big difference."
