Electrochemical biosensor yog ib qho technology uas hloov cov tshuaj tawm ntawm cov hluav taws xob los ntawm kev tshua nrog cov kev qhia biometrics rau hauv hluav taws xob. Nws muaj qhov zoo ntawm kev siab zog, ceev ceev teb, qis dua thiab kev txav me me, thiab plays lub luag haujlwm tseem ceeb hauv kev tshuaj, chaw kuaj, kuaj xyuas thiab cais tawm. Hlau oxide pom lub tsev nrog kev ua kom muaj kev ua tau zoo yog ib qho tseem ceeb ntawm txoj kev loj hlob ntawm cov hluav taws xob biosensors. Txawm li cas los xij, txoj kev tsis tshua muaj neeg sib txawv ntawm cov hlau oxide paub qhov tseeb ua rau cov txheej txheem hluav taws xob hloov hauv cov txheej txheem ntawm cov tshuaj tiv thaiv, thiab qhov kev ua kom pom tsis zoo. Yog li ntawd, los ntawm kev xav ntawm tsim cov qauv ntawm high-efficiency electrochemical biosensor electrode, nws tau ua kom pom tseeb thiab kev nyuaj ntawm qhov kev ua no los tsim qhov hloov dua tshiab chav tsev ntawm nanometer thin film qauv nrog high conductivity mus thauj lub cim kev qhia ntawm cov kev ua kom muaj kev ua haujlwm siab.
Hlau los ntawm shenyang lub teb chaws tshawb nrhiav ntawm cov ntaub ntawv tshawb fawb, ntaub ntawv membrane thiab interface pab pawg neeg Jiang Xin tshawb, Dr. Graduate ZhaiChaoFeng Huang Nan associate xibfwb qhia, siv CVD, PVD thiab electrochemical oxidation tshuab tsim lub hom tshiab pob zeb diamond / carbon nanotubes phab ntsa CuO 3 d mesh electrochemical sensing electrode thiab siv nyob rau hauv lub txiaj ntsim ntawm cov kab mob qabzib. Cov electrochemical sensing electrode tsom qhia tawm dav dav (0.5 x 106-4 x 103 M), siab rhiab heev (1650 A 1 cm - 2 hli), tsis tshua muaj kev txwv thiab xaiv selectivity, zoo reproducibility thiab ntev mus ntev, thiab kawm ntxiv tau pom tias cov electrode nyob rau hauv kev soj ntsuam ntawm tib neeg cov ntshav dej uas qhia A rov qab zoo npaum li cas (94.21 104.18%), muaj peev xwm ntawm kev paub txog kev sib xyaw ua muaj roj ntsha heev.
Cov kev tshwm sim qhia tau hais tias qhov zoo tshaj plaws ntawm cov hluav taws xob hlau tsom xam los ntawm pob zeb diamond / carbon nanowall nyias zaj duab xis electrodes nrog zoo heev lub cev thiab tshuaj. Ntawm qhov one hand, carbon nanowires muaj li ntawm cov duab ntawm daim duab graphene uas loj hlob yuav luag txhua yam rau cov substrate. Lawv tsis tsuas yog muaj hluav taws xob conductivity thiab qhov loj tshwj xeeb deg thaj tsam, tab sis kuj muaj nplua graphite sawv nrog siab electrochemical kev ua si, ntxeem tau yooj yim uas hloov yooj yim, nyuaj agglomerate thiab ruaj ntseg qauv. Ntawm qhov tod tes, pob zeb diamond nrog cov tub ntxhais hluas qhov kev ua si tau sau los ntawm tag nrho cov yeeb yaj kiab zaj duab xis electrode nyob rau hauv daim ntawv ntawm nano-sheet, uas ntxiv kev txhim kho cov khoom siv dag zog ntawm cov electrode nyob rau hauv daim ntawv thov txheej txheem. Cov qauv ntawm qhov sib txawv ntawm peb lub network no tuaj yeem ua kom cov huab cua hloov mus rau qhov sib xyaw, thiab rov qab xa cov electrons los ntawm cov khoom siv hluav taws xob los ntawm cov khoom siv hluav taws xob hauv lub sij hawm, yog li pom cov qauv hluav taws xob zoo thiab qhov ntev mus ntev. Tsis tas li ntawd, 3d mesh electrochemical sensor electrode tseem siv tau los thauj lwm yam biometrics, uas qhia zoo tshaj plaws hauv lub tshav pob ntawm cov hluav taws xob ua tau hluav taws xob biosensors. Cov pa roj carbon monoxide yuav tau muaj kev tshawb fawb tus nqi ntawm cov khoom siv hluav taws xob thiab kev hloov, electrocatalysis thiab lwm yam. Lwm yam kev tshawb fawb tau muab luam tawm rau hauv Me (hauv xovxwm, https://doi.org/10.1002/smll.201901527).
Cov kev tshawb fawb saum toj saud no tau raug nyiaj los ntawm lub teb chaws natural science foundation ntawm Tuam Tshoj, lub koom haum science thiab technology ntawm liaoning xeev thiab cov kev ua haujlwm ntawm kev tshawb fawb txog kev lag luam ntawm shenyang.

NPAJ. 2 electrode rhiab heev, cuam tshuam txog kev cuam tshuam, selectivity thiab stability ntev ntawm CuO electrochemical sensor loaded nrog 3d pob zeb diamond / carbon nanowall
