The striations are the sunscreen distributed across sample. Optisol is a trademarked nanotechnology photostable ultrafine titanium dioxide UV absorber cream that provides enhanced and longer lasting protection against UVA in suncare and antiageing products. Optisol also reduces the formation of free radicals produced from exposure to the sun which are implicated in premature skin ageing. The company Oxonica has developed Optisol and produces Commercial Solutions in Nanotechnology. The science and technology of building electronic circuits and devices from single atoms and molecules and giving them special electrical and chemical properties. Nanotechnology is seen to have the potential in the product applications of many technologies from energy and the environment, information and communication, semiconductors and chemicals, medical and forensic science, drugs and in the production of stronger, lighter materials. A nanometre or nm is one billionth of a metre, meter. A very small size scale.
