About this image

Scanning electron micrograph of ‘nanoswimmers’. These are microscopic objects being investigated for use as drug carriers in medicine. Each tiny coil is just 25 micrometres long, 5 micrometres wide and 300 nanometres thick. The coils are made from a polymer coated in nickel and titanium. This image was captured in monochrome then later digitally colourised by Ms A Cavanagh. University College London School of Pharmacy, 29-29 Brunswick Square, London, United Kingdom
