Kev siv graphene hauv electrochemical sensors

      Cov pa roj carbon nanomaterials feem ntau muaj qhov tshwj xeeb ntawm thaj chaw,conductivity zoo heevthiab biocompatibility, uas zoo kawg nkaus ua tau raws li cov kev xav tau ntawm cov khoom siv hluav taws xob electrochemical. Raws li ib tug neeg sawv cev ntawmcov khoom siv carbons nrog lub peev xwm zoo, graphene tau lees paub tias yog cov khoom siv hluav taws xob zoo heev. Cov kws tshawb fawb thoob plaws ntiaj teb tab tom kawm graphene, uas tsis ntseeg tau ua lub luag haujlwm tseem ceeb hauv kev txhim kho electrochemical sensors.
Wang et al. Siv cov khoom npaj Ni NP / graphene nanocomposite hloov kho electrode los kuaj cov piam thaj. Los ntawm cov synthesis ntawm tshiab nanocomposites hloov nyob rau hauv lubelectrode, series ntawm kev sim tej yam kev mob tau optimized. Cov txiaj ntsig tau pom tias lub sensor muaj qhov txwv tsis pub pom thiab siab rhiab heev. Tsis tas li ntawd, qhov kev sim cuam tshuam ntawm lub sensor tau ua tiav, thiab cov electrode tau pom zoo los tiv thaiv kev cuam tshuam rau uric acid.
Ma et al. Npaj lub tshuab hluav taws xob hluav taws xob raws li 3D graphene Ua Npuas Ncauj / paj zoo li nano CuO. Lub sensor tuaj yeem siv ncaj qha rau kev tshawb pom ascorbic acid, nrogsiab rhiab heev, teb ceev ceev thiab lub sij hawm teb tsawg dua 3S. Lub tshuab hluav taws xob hluav taws xob rau kev tshawb pom sai ntawm ascorbic acid muaj peev xwm ua tau zoo rau daim ntawv thov thiab xav tias yuav tsum tau siv ntxiv rau hauv kev siv tswv yim.
Li et al. Synthesized thiophene sulfur doped graphene, thiab npaj dopamine electrochemical sensor los ntawm enriching S-doped graphene nto micropores. Lub sensor tshiab tsis tsuas yog qhia tau hais tias muaj zog xaiv rau dopamine thiab tuaj yeem tshem tawm kev cuam tshuam ntawm ascorbic acid, tab sis kuj muaj qhov rhiab heev nyob rau hauv thaj tsam ntawm 0.20 ~ 12 μ Qhov kev kuaj pom yog 0.015 μ M.
Liu et al. Synthesized cuprous oxide nanocubes thiab graphene composites thiab hloov lawv ntawm lub electrode los npaj ib tug tshiab electrochemical sensor. Lub sensor tuaj yeem kuaj xyuas hydrogen peroxide thiab qabzib nrog cov kab sib luag zoo thiab kuaj pom qhov txwv.
Guo et al. Ua tiav cov khoom sib xyaw ntawm nano kub thiab graphene. Los ntawm kev hloov kho ntawm lubsib xyaw, ib qho tshiab isoniazid electrochemical sensor tau tsim. Lub tshuab hluav taws xob hluav taws xob tau pom qhov ntsuas pom tau zoo thiab muaj txiaj ntsig zoo hauv kev tshawb pom ntawm isoniazid.
