Kev kho deg ntawm microplates yog qhov tseem ceeb rau qhov raug thiab rov ua dua tshiab ntawm cov txiaj ntsig kev sim. Cov kev kho saum npoo feem ntau suav nrog kev xaiv hydrophilic thiab hydrophobic. Hydrophilic kev kho mob txhim kho qhov kev sib raug zoo ntawm cov dej, ua kom cov kua sib kis hauv cov qhov dej, txo cov npuas tsim, thiab txhim kho qhov tseeb ntawm qhov dej; Txoj kev no feem ntau siv rau hauv kev sim uas yuav tsum tau muab cov kua thiab sib tov, xws li ELISA thiab kab lis kev cai ntawm tes. Hloov pauv, kev kho hydrophobic txo cov kua dej ntawm cov phab ntsa zoo thiab tiv thaiv kev sib kis ntawm cov qauv, yog li txhim kho qhov tseeb ntawm kev sim; Txoj kev no feem ntau yog siv rau hauv cov txheej txheem uas muaj kev ntxuav thiab yaug cov kauj ruam, xws li immunohistochemistry.
Tsis tas li ntawd, qee cov microplates tau txais kev kho mob tshwj xeeb-xws li covalent bonding ntawm biomolecules zoo li cov proteins lossis cov tshuaj tiv thaiv-ua kom lawv muaj peev xwm adsorption rau cov biomolecules tshwj xeeb, yog li txhim kho kev sim siab thiab qhov tshwj xeeb.
