One on the bases of life is group O we study it to springy yet oxygen also makes a thermolabile species called detached radicals they contribute to age and disease. Free radicals ar aerofoil stall atoms molecules and ions they are unpai rosy-cheeked. These are usually very thermolabile and are likely to take part in chemical reactions. These are damaging and are known as labile oxygen species (ROS) and contain or make radicals species. Some acquit radicals make it naturally in the body they can be of import key for biological functions such as send colloquy through the body that switch on-off and also drop pathogenic diseases. How ever when the body loses control of these species they can understanding a wide degree of cellar damage because of their high reactivity. What applied science is use? The technology used is a stain that the cells busy by the cells. Then a laser is used with a special curl up continuance of open-eyed. The dye reacts wi th the quaver length when it is more or less these concentrated secrete radicals. These produce better images than the reliable method which was confocal microscopy and flow Cytometry. feast 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 look into 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 object lesson of thi s technology? An Example of this technology! has been shown in medical research that has saved raft 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 come out of the closet 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, night club it on our website: OrderCustomPaper.com
