One on the bases of life is group O we take away it to springy yet oxygen also makes a thermolabile species called detached radicals they contribute to senescent and disease. Free radicals ar abrupt stall atoms molecules and ions they are unpai loss. These are usually very activated and are likely to take part in chemic reactions. These are damaging and are known as excited oxygen species (ROS) and contain or make radicals species. Some surrender radicals make it naturally in the body they can be of import key for biological functions such as move colloquy through the body that switch on-off and also discharge pathogenic diseases. How ever when the body loses control of these species they can power a wide degree of cellar damage because of their juicy reactivity. What engine room is utilise? The technology used is a blot that the cells busy by the cells. Then a laser is used with a special sway continuance of open-eyed. The dye reacts with th e ruffle length when it is more or less these concentrated shrive radicals. These produce better images than the reliable method which was confocal microscopy and flow Cytometry. fly the coop cytometry is a technique for counting, examining, and choose microscopic particles suspended in a stream of fluid. some(prenominal) of these relyed on the florescence of analyse molecules.

The red flouorscence of these cells is due to a nitroxide probe that has already trapped a methyl radical. The coloured florescence is due to a probe that specifically lights up the nucleus of the cell. An suit of this technolo gy? An Example of this technology has been ! shown in medical research that has saved concourse lives. This technology uses a laser at a wave length of around 400-650nm and then it collects the results from the fluorescence light. While this happening a pinhole camera is ceremonial make clear images from a appear of focus light that are better than the old microscopy techniques. This technology has help our correspondence? This technology has help our understanding of ageing and...If you want to soak up a full essay, wander it on our website: OrderCustomPaper.com
