Cov kws tshawb fawb ntawm Tsev Kawm Ntawv Pritzker ntawm cov molecular engineering nyob rau hauv University of Chicago tau tsim kho cov ntaub ntawv ntawm cov ntaub ntawv nyob ntawm cov ntaub so ntswg thiab cov tshuab. Nws tuaj yeem siv rau cov cuab yeej kho mob kho mob thiab cov khoom siv tsis phais mob. Cov Duab: Pritzker Tsev Kawm Ntawv ntawm cov molecular engineering ntawm University of Chicago
Cov khoom siv hluav taws xob zoo rau kev sib txuas cov ntaub ntawv hluav taws xob thiab cov ntaub so ntswg uas yuav tsum yog mos, ncab thiab hydrophilic, zoo ib yam li cov hydrogels. Cov ntaub ntawv semiconductor feem ntau nyuaj, nkig thiab tsis muaj qab hau, thiab tsis tuaj yeem yaj hauv dej zoo li hydrogels. Yog tias muaj cov khoom siv hluav taws xob muaj nyob rau hauv cov khoom siv roj ntsha xws li cov pa roj ntsha, biosensors thiab cov khoom siv menyuam tshuaj, cov kev tsis txaus siab no tau ua rau muaj kev loj hlob loj loj.
Cov khoom siv tshiab ua yeeb yam ntawm qib-qib ntawm txog li 81 kPA, thiab cov cab kuj muaj txog li 1.4 square centimeters / volt-vib nas this. Qhov no qhia tau hais tias cov khoom no, uas muaj ob qho tib si semiconductor thaj chaw thiab hydrogel cov khoom, ua tau txhua yam yuav tsum muaj rau cov kev xav tau zoo tagnrho Bioelectronic interface.
Txij li thaum cov khoom siv los ntawm cov khoom siv xyoob ntoo yog qhov sib chwv nrog cov ntaub so ntswg, lawv yuav tsum muaj peev xwm deformes los ua cov ntaub so ntswg sib xyaw ua ke.
Cov txheej txheem ib txwm npaj hydrogels yog kom yaj cov khoom hauv dej thiab tom qab ntawd ntxiv nws kom tig qhov kev daws teeb meem rau hauv lub xeev gel. Txawm li cas los xij, cov ntaub ntawv semiconductor feem ntau yog insoluble hauv dej. Txog rau qhov kawg no, pab neeg tsim cov txheej txheem kev hloov pauv. Hloov chaw ntawm semiconductor nyob rau hauv dej, nws yog yaj nyob rau hauv ib organic kuab uas yog mistible. Tom qab ntawd, lawv siv cov semaws semiconduct thiab hydrogel precursor los npaj nws.
Thawj cov khoom lag luam yog cov organic gel. Pab neeg no ces soaks tag nrho cov ntaub ntawv hauv dej kom yaj cov organic organic thiab cia dej kom nkag mus rau nws. Cov khoom siv tau los ua tau dav siv ntau lub polymer soob semiconductors nrog cov haujlwm sib txawv.
Nws yog tsim nyog sau uas piv nrog cov khoom siv roj ntsha, cov khoom siv tshiab tsis tsuas yog ua kom muaj kev ua haujlwm biological lossis semiconductor hauv ntau yam, ua tiav zoo dua cov teebmeem.
Qhov kev tshawb fawb no tseem yuav daws tau cov kev cov nyom ntawm cov cuab yeej kho mob uas tsis muaj txiaj ntsig, tab sis nws kuj muaj ntau txoj kev nyeem ntawv ntawm daim tawv nqaij cov ntaub ntawv thiab txhim kho cov txiaj ntsig kev saib xyuas. Cov khoom muaj cov khoom siv tsis tshua muaj zog thiab cov ntsiab lus dej siab, uas zoo ib yam li cov nqaij uas muaj sia nyob. Nyob rau tib lub sijhawm, nws tseem muaj ntxeem tau, uas txhais tau tias ntau yam khoom noj muaj kuab thiab tshuaj lom tau. Thaum tag nrho cov khoom no tau sib xyaw ua ke, cov khoom siv tshiab yuav dhau los ua ib qho ntawm cov ntaub ntawv muaj peev xwm tshaj plaws hauv cov ntaub so ntswg thiab kev xa tshuaj.
Qhov kev tshawb fawb no tseem yuav tsom rau kev daws teeb meem cov kev cov nyom uas muaj cov khoom siv kho mob xws li cov ntaub ntawv kho mob tsis muaj txiaj ntsig, tab sis yog muaj ntau txoj kev nyeem ntawv ntawm cov tawv nqaij thiab txhim kho cov txiaj ntsig cov txhab. Cov khoom muaj cov khoom siv tsis tshua muaj zog thiab cov ntsiab lus dej siab, uas zoo ib yam li cov nqaij uas muaj sia nyob.
