Muaj ntau hom khoom noj, cov khoom siv ntev ntev, thiab nyuaj rau kev saib xyuas kev nyab xeeb. Kev kuaj xyuas tshuab yog ib txoj hauv kev tseem ceeb los xyuas kom muaj kev nyab xeeb ntawm zaub mov. Txawm li cas los xij, cov thev naus laus zis tshawb pom tam sim no ntsib cov teeb meem hauv kev tshawb nrhiav kev nyab xeeb khoom noj, xws li cov khoom siv tsis zoo ntawm cov khoom tseem ceeb, cov qauv ua ntej kev kho mob ntev, kev ua kom zoo dua qub, thiab kev xaiv qis ntawm cov khoom tseem ceeb xws li cov khoom siv loj spectrometry ion, uas ua rau lub sij hawm ntawm kev soj ntsuam cov khoom noj. Tau ntsib nrog cov kev cov nyom, peb cov kws tshaj lij pab pawg thawj coj los ntawm Zhang Feng tau ua tiav cov txheej txheem thev naus laus zis hauv kev tshawb fawb cov lus qhia ntawm cov ntaub ntawv tseem ceeb, cov khoom tseem ceeb, thiab cov txheej txheem tshiab rau kev soj ntsuam kev nyab xeeb khoom noj.
Nyob rau hauv cov nqe lus ntawm kev tshawb fawb thiab kev loj hlob ntawm cov ntaub ntawv tseem ceeb, pab neeg no tau tshawb nrhiav qhov tshwj xeeb adsorption mechanism ntawm pre-kho cov ntaub ntawv ntawm cov teeb meem tshuaj nyob rau hauv cov zaub mov, thiab tsim ib tug series ntawm heev tshwj xeeb adsorption micro nano qauv pre-kho cov ntaub ntawv. Kev tshawb nrhiav cov hom phiaj ntawm cov kab mob / ultra trace theem yuav tsum tau kho ua ntej rau kev txhim kho thiab ua kom huv si, tab sis cov ntaub ntawv uas twb muaj lawm muaj peev xwm ua kom muaj txiaj ntsig zoo thiab tsis txaus, ua rau kev tshawb pom rhiab heev tsis ua raws li qhov yuav tsum tau tshawb pom. Pib los ntawm cov qauv molecular, pab pawg tau txheeb xyuas qhov tshwj xeeb adsorption mechanism ntawm cov khoom siv kho mob ua ntej ntawm cov khoom tsis zoo hauv cov zaub mov, qhia cov pab pawg ua haujlwm xws li urea, thiab npaj cov khoom siv cov ntaub ntawv covalent organic nrog cov tshuaj tiv thaiv kev cai (Fe3O4@ETTA-PPDI Fe3O4@TAPB-BTT thiab Fe3PPO4 nto ntawm TA. Siv rau kev txhim kho thiab ua kom huv ntawm cov khoom tsis zoo xws li aflatoxins, fluoroquinolone veterinary tshuaj, thiab phenylurea herbicides hauv cov zaub mov, lub sijhawm kho ua ntej luv luv los ntawm ob peb teev mus rau ob peb feeb. Piv nrog rau lub teb chaws tus qauv txoj kev, qhov kev tshawb nrhiav rhiab heev yog nce los ntawm ntau tshaj li ib puas lub sij hawm, tawg los ntawm kev teeb meem ntawm cov khoom siv tsis zoo uas ua rau cumbersome pre-kho cov txheej txheem thiab tsis tshua pom kev rhiab heev, uas nyuaj rau ua tau raws li qhov yuav tsum tau nrhiav kom tau.
Nyob rau hauv kev tshawb fawb thiab kev loj hlob kev taw qhia ntawm cov ntsiab lus tseem ceeb, pab neeg no yuav cais cov ntaub ntawv tshiab thiab integrate lawv nrog huab hwm coj spectrometry ion qhov chaw los tsim ib tug heev xaiv pawg spectrometry ion qhov chaw Cheebtsam thiab real-time mass spectrometry ceev nrhiav kom tau txoj kev. Tam sim no, feem ntau siv colloidal kub kuaj strips rau ntawm qhov chaw soj ntsuam ceev yog me me thiab portable, tab sis lawv qhov zoo thiab ntau qhov tseeb yog qhov tsawg. Mass spectrometry muaj qhov zoo ntawm qhov raug siab, tab sis cov cuab yeej yog loj thiab yuav tsum tau ua qauv ua ntej thiab cov txheej txheem chromatographic sib cais, ua rau nws nyuaj rau kev siv rau ntawm qhov chaw nrhiav kom tau sai. Pab neeg no tau tawg los ntawm lub bottleneck ntawm lub sij hawm tam sim no loj spectrometry ion qhov chaw tsuas yog muaj ionization muaj nuj nqi, thiab qhia ib tug series ntawm kev sib cais cov ntaub ntawv hloov kho technologies mus rau hauv huab hwm coj spectrometry ion qhov chaw, ua kom ion qhov chaw muaj kev sib cais muaj nuj nqi. Nws muaj peev xwm purify complex qauv matrices xws li zaub mov thaum ionizing lub hom phiaj tshuaj, tshem tawm cov cumbersome chromatographic sib cais ua ntej zaub mov pawg spectrometry tsom xam, thiab tsim ib tug series ntawm kev sib cais ionization integrated real-time mass spectrometry ion qhov chaw. Yog tias cov khoom tsim tawm molecularly imprinted yog ua ke nrog cov khoom siv hluav taws xob los tsim cov khoom loj spectrometry ion qhov chaw tshiab (raws li qhia hauv daim duab 2), ib txoj kev tshawb nrhiav ceev ceev hauv lub sijhawm yog tsim los rau kev tshawb nrhiav cov carbamate esters hauv cov khoom noj, nrog rau kev tshawb nrhiav ceev ntawm ≤ 40 vib nas this thiab ib qho kev txwv kom muaj nuj nqis 5. ntawm g / kg tau raug txo los ntawm kaum tawm feeb mus rau kaum vib nas this, thiab qhov rhiab heev tau raug txhim kho los ntawm ze li ntawm 20 lub sij hawm, daws qhov teeb meem ntawm qhov tsis txaus ntawm qhov tseeb ntawm qhov chaw kuaj khoom noj khoom haus.
Nyob rau hauv 2023, pab neeg no tau ua tiav ib tug series ntawm breakthroughs nyob rau hauv lub tshiab technology kev nyab xeeb kev soj ntsuam khoom noj khoom haus, tsim 8 tshiab purification thiab enrichment cov ntaub ntawv thiab 3 tshiab loj spectrometry ion cov ntsiab lus; Thov rau 15 invention patents; 14 tso cai tsim patents; Tau txais 2 software copyrights; Tsim 9 cov qauv kev nyab xeeb zaub mov thiab luam tawm 21 cov ntawv hauv cov ntawv xov xwm hauv tsev thiab txawv teb chaws, suav nrog 8 SCI Zone 1 TOP cov lus.
