Electron microscopes yog siv txhawm rau tshawb xyuas ultrastructure ntawm ntau hom kab mob lom thiab inorganic nrog rau cov kab mob, cov hlwb, cov molecules loj, cov qauv biopsy, hlau, thiab crystals. Kev lag luam, electron microscopes feem ntau siv rau kev tswj kom zoo thiab tsis ua hauj lwm tsom xam.

Ua raws li qhov kev pom no, dab tsi yog electron microscope thiab nws siv rau dab tsi?

Electron microscopy (EM) yog cov txheej txheem kom tau txais cov duab daws teeb meem siab ntawm cov kab mob lom thiab tsis yog lom. Nws yog siv Hauv kev tshawb fawb biomedical los tshawb xyuas cov qauv nthuav dav ntawm cov ntaub so ntswg, hlwb, organelles thiab macromolecular complexes.

Ib sab saum toj no, dab tsi yog 3 hom electron microscopes? Muaj ntau ntau hom electron microscopes, suav nrog kis tau tus mob electron microscope (TEM), scanning electron microscope (SEM), thiab reflection electron microscope (REM.)

Kuj tseem yuav paub yog, vim li cas cov electrons siv hauv lub tshuab tsom iav?

Electron Microscope . Ib electron microscope tso cai rau peb pom ntawm cov nplai me me no. Electron microscopes ua haujlwm los ntawm kev siv ib qho hluav taws xob beam es tsis txhob pom lub teeb thiab ib qho hluav taws xob detector es tsis txhob ntawm peb ob lub qhov muag. Ib hluav taws xob beam tso cai rau peb pom ntawm cov nplai me me vim electrons kuj coj tau lub teeb.

Dab tsi yog qhov siab tshaj plaws ntawm electron microscope?

Qhov kev daws teeb meem ntawm electron microscopes yog 0,2nm siab kawg pab tau magnification ib electron microscope tuaj yeem muab yog li 1,000,000x.
