熒光分析法(fluorescenceanalysis
熒光光譜基礎; 蛋白質的熒光特性; 熒光分光光度計的結構和原理。吸收光譜和熒光光譜能級躍遷示意圖 (一)熒光的產生 某些物質受紫外光或可見光照射激發后能發射出比激發光波長較長的熒光。此化學物質能從外界吸收并儲存能量(如光能、化學能等)而進入激發態,當其從激發態再回復到基態時,過剩的能量可以電磁輻射的形式放射(即發光)。熒光發射的特點是:可產生熒光的分子或原子在接受能量后即刻引起發光;而一旦停止供能,發光(熒光)現象也隨之在瞬間內消失。 可以引起發射熒光的能量種類很多,由光激發所引起的熒光稱為致熒光。由化學反應所引起的稱為化學熒光,由X線或陰極射線引起的分別稱為X線熒光或陰極射線熒光。熒光免疫技術一般應用致熒光物質進行標記。(二)熒光效率 熒光分子不會將全部吸收的光能都轉變成熒光,總或多或少地以其他形式釋放。熒光效率是指熒光分子將吸收的光能轉變成熒光的百分率,與發射熒光光量子的數值成正比。 熒光效率=發射熒光的光量分子數(熒光強度......閱讀全文
