Qhov tseeb ntawm cov tshuab hluav taws xob thiab cov tshuab microscopes kho qhov muag sib txawv nyob ntawm hom thiab kev tsim, raws li nram no:
Kev meej ntawm lub tshuab hluav taws xob microscopy
Kev Siv Lub Tshuab Microscope Hluav Taws Xob (TEM): Tam sim no, qhov kev daws teeb meem tseeb ntawm kev siv lub tshuab microscope hluav taws xob tau daws tau cov qauv hauv qab 0.2μm, thiab qhov kev daws teeb meem ntawm qhov txwv tsis pub dhau tuaj yeem ncav cuag 0.1nm. Piv txwv li, qee lub tshuab microscope hluav taws xob zoo muaj qhov kev daws teeb meem ntawm 1.5 txog 2A (1A = 0.1nm), uas tuaj yeem daws tau yuav luag txhua lub atoms.
Kev siv tshuab hluav taws xob scanning (SEM): Feem ntau qhov kev daws teeb meem ntawm 1μm³ yog ua tiav, txawm hais tias qhov tseeb yuav txawv nyob ntawm hom khoom siv thiab cov xwm txheej saib.
Qhov tseeb ntawm lub teeb microscopy
Kev siv lub tshuab tsom iav dav dav: nws qhov kev daws teeb meem feem ntau yog li 250nm, uas yog 1 lab npaug siab dua qhov kev daws teeb meem ntawm lub qhov muag tib neeg (0.25mm). Txawm li cas los xij, qhov kev daws teeb meem thiab kev loj hlob ntawm lub tshuab tsom iav tuaj yeem txhim kho tau zoo los ntawm kev siv cov iav siab thiab cov txheej txheem kho qhov muag.
Lub tshuab tsom iav kho qhov muag siab: xws li lub tshuab tsom iav kho qhov muag digital, nws qhov kev daws teeb meem tuaj yeem ncav cuag 0.1μm, magnification txog li 5000 zaug. Tsis tas li ntawd, muaj cov cuab yeej ntsuas kev ntsuas siab raws li lub hauv paus ntsiab lus ntawm kev cuam tshuam dawb xws li lub tshuab tsom iav kho qhov muag peb-seem, uas tuaj yeem ua tiav kev ntsuas qhov chaw saum npoo av nrog kev daws teeb meem subnanometer.
Kev siv lub tshuab tsom iav tshwj xeeb: xws li kev siv lub tshuab tsom iav nrog 2nm qhov tseeb, xws li thev naus laus zis MINFLUX, cim tias kev siv lub tshuab tsom iav daws teeb meem nanoscale tau nkag mus rau hauv kev tshawb fawb txog lub neej.
