Tus kws tshawb fawb Askiv Sir George G. Stokes thawj zaug piav qhia txog fluorescence hauv xyoo 1852 thiab nws yog lub luag haujlwm rau coining lub sij hawm thaum nws pom tias cov ntxhia fluorspar tawm lub teeb liab thaum nws tau illuminated los ntawm ultraviolet. kev zoo siab.
Thaum twg tau fluorescent microscopy tsim?
thawj fluorescence microscopes tau tsim nruab nrab ntawm 1911 thiab 1913 los ntawm German physicists Otto Heimstaedt thiab Heinrich Lehmann raws li kev sib tw los ntawm cov cuab yeej ultraviolet. Cov tshuab ntsuas no tau ua haujlwm los soj ntsuam autofluorescence hauv cov kab mob, tsiaj txhu, thiab cov ntaub so ntswg.
Lub tshuab ntsuas fluorescence siv rau dab tsi?
Fluorescence microscopy yog qhov rhiab heev, tshwj xeeb, txhim khu kev qha thiab siv dav los ntawm cov kws tshawb fawb los saib xyuas qhov chaw ntawm cov molecules hauv hlwb, thiab ntawm cov hlwb hauv cov ntaub so ntswg.
Lub hauv paus ntsiab lus ntawm fluorescence microscopy yog dab tsi?
Fluorescence microscopy yog hom lub teeb tsom iav uas ua haujlwm ntawm lub hauv paus ntsiab lus ntawm fluorescence. Ib yam khoom tau hais tias yog fluorescent thaum nws nqus lub zog ntawm qhov pom tsis pom luv luv ntawm lub teeb hluav taws xob (xws li UV lub teeb) thiab emits ntev wavelength hluav taws xob ntawm pom lub teeb (xws li lub teeb ntsuab lossis liab).
Leej twg tsim lub teeb microscopy?
History of the Light Microscope
Lub teeb tsom iav hnub tsawg kawg rau 1595, thaum Zacharias Jansen (1580–1638) ntawm Holland tau tsim lub teeb sib xyawmicroscope, ib qho uas siv ob lub lo ntsiab muag, nrog rau lub lens thib ob ntxiv kom pom cov duab tsim los ntawm thawj zaug.
