Optical microscopes tuaj yeem soj ntsuam cov qauv molecular
Optical microscope thiab electron microscope yog ob hom kev tsom xam, nrog qhov sib txawv ntawm kev txhais, kev faib tawm, thiab muaj pes tsawg leeg.
1. Cov ntsiab lus txawv
Optical Microscope (OM) yog ib qho cuab yeej kho qhov muag uas siv cov qauv kho qhov muag kom nthuav dav thiab duab cov khoom me me uas tsis tuaj yeem ua qhov txawv ntawm tib neeg lub qhov muag, txhawm rau rho tawm cov ntaub ntawv microstructural.
Daim ntawv thov ntawm electron microscopy technology yog raws li lub hauv paus ntawm optical microscopy. Qhov kev daws teeb meem ntawm optical microscopy yog {{0}}}.2 μ m, thiab qhov kev daws teeb meem ntawm kev xa hluav taws xob microscopy yog 0.2 nm, uas txhais tau hais tias kev xa hluav taws xob microscopy nthuav dav 1000 npaug ntawm lub hauv paus ntawm optical microscopy.
2. Kev faib tawm txawv
Muaj ntau txoj hauv kev rau kev kho qhov muag microscopes, uas tuaj yeem muab faib ua peb hom raws li tus naj npawb ntawm cov eyepieces siv: binocular, thiab monocular microscopes; Raws li seb daim duab puas muaj kev nkag siab ntawm stereoscopy, nws tuaj yeem muab faib ua lub tso suab tsis pom kev thiab tsis pom lub tso suab microscopes; Raws li cov khoom pom, nws tuaj yeem muab faib ua cov khoom siv roj ntsha thiab metallographic microscopes, thiab lwm yam; Raws li cov txheej txheem kho qhov muag, nws tuaj yeem muab faib ua polarization, theem sib piv, thiab qhov sib txawv cuam tshuam qhov sib txawv ntawm microscopy.
Electron microscopes tuaj yeem muab faib ua kis tau tus mob electron microscopes, scanning electron microscopes, reflection electron microscopes, thiab emission electron microscopes raws li lawv cov qauv thiab lub hom phiaj.
Tam sim no, cov molecules yuav luag indistinct nyob rau hauv lub microscopes, tsis yog vim lub magnification tsis txaus, tab sis vim hais tias kev daws teeb meem ntawm optical microscopes ncav cuag. Qhov kev daws teeb meem siab STORM tam sim no nyob ib puag ncig 20nm, uas txhais tau hais tias ob lub ntsiab lus sib cais los ntawm ntau dua 20 nanometers tuaj yeem pom meej, thaum cov hauv qab 20 nanometers tuaj yeem pom.
Molecules tsawg kawg ntawm nanoscale, thiab nws nyuaj rau hais yog tias peb siv electron microscopy. Qhov loj ntawm electron microscopy tuaj yeem ncav cuag 10000 zaug, thiab qhov kev daws teeb meem ntawm electron microscopy yog nyob ntawm nanoscale. Tib lub sijhawm, kuv xav qhia koj tias kev daws teeb meem tseem ceeb heev. Yog tias qhov kev daws teeb meem tsis tuaj yeem ua tiav, txawm tias qhov kev nthuav dav siab tsis muaj txiaj ntsig.
