Correlation between melanin levels and free radical formation in human cells following illumination by ultraviolet A light.
Melanin is a naturally-occurring pigment that is largely responsible for skin colour. It absorbs the ultraviolet and blue components of sunlight, thus preventing the photochemical formation of free radicals that can damage DNA in the skin. In darkly pigmented skin,...
Microwave Spectroscopy of a Carbon Nanotube Charge Qubit
The use of quantum dots to define charge and spin qubits is well established in the field of quantum information processing. Quantum dot charge qubits are attractive because of the possibility of fast qubit control but are sensitive to charge noise which can result in...
Nanotechnology to leverage infections and antibiotic sensing
“Miniaturized diagnostic tests can revolutionize the speed of diagnosing infectious diseases and hereditary ones such as haemophilia,” said Dr Joseph Ndieyira of UCL, senior author of a paper that has just been published in Nature Nanotechnology. Infections caused by...
