Kev siv graphene hauv cov sensors electrochemical

      Cov khoom siv carbon nano feem ntau muaj thaj chaw tshwj xeeb siab,kev coj ua zoo heevthiab biocompatibility, uas ua tau raws li qhov yuav tsum tau ua ntawm cov ntaub ntawv electrochemical sensing. Raws li tus sawv cev ntawmcov khoom siv carbonNrog rau lub peev xwm loj heev, graphene tau raug lees paub tias yog cov khoom siv electrochemical zoo heev. Cov kws tshawb fawb thoob plaws ntiaj teb tab tom kawm txog graphene, uas tsis muaj qhov tsis ntseeg ua lub luag haujlwm tseem ceeb hauv kev tsim cov sensors electrochemical.
Wang et al. Siv cov electrode Ni NP / graphene nanocomposite hloov kho uas tau npaj tseg los ntes cov piam thaj. Los ntawm kev tsim cov nanocomposites tshiab hloov kho rau ntawmhluav taws xob, ib qho kev sim ua tau zoo dua. Cov txiaj ntsig qhia tau tias lub sensor muaj qhov txwv tsis pub kuaj pom thiab muaj kev nkag siab zoo. Tsis tas li ntawd, qhov kev sim cuam tshuam ntawm lub sensor tau ua tiav, thiab lub electrode tau qhia txog kev ua tau zoo tiv thaiv kev cuam tshuam rau uric acid.
Ma et al. Tau npaj ib lub tshuab ntsuas hluav taws xob raws li 3D graphene Foams / paj zoo li nano CuO. Lub sensor tuaj yeem siv ncaj qha rau kev kuaj pom ascorbic acid, nrogkev nkag siab siab, qhov teb ceev ceev thiab lub sijhawm teb tsawg dua 3S. Lub tshuab hluav taws xob electrochemical rau kev ntes sai ntawm ascorbic acid muaj peev xwm zoo rau kev siv thiab xav tias yuav raug siv ntxiv rau hauv kev siv tswv yim.
Li et al. Synthesized thiophene sulfur doped graphene, thiab npaj dopamine electrochemical sensor los ntawm kev nplua nuj S-doped graphene nto micropores. Lub sensor tshiab tsis tsuas yog qhia txog kev xaiv muaj zog rau dopamine thiab tuaj yeem tshem tawm kev cuam tshuam ntawm ascorbic acid, tab sis kuj muaj kev rhiab heev zoo hauv qhov ntau ntawm 0.20 ~ 12 μ. Qhov txwv tsis pub kuaj pom yog 0.015 μ M.
Liu et al. Synthesized cuprous oxide nanocubes thiab graphene composites thiab hloov kho lawv ntawm lub electrode los npaj lub electrochemical sensor tshiab. Lub sensor tuaj yeem ntes hydrogen peroxide thiab glucose nrog qhov zoo linear ntau thiab qhov txwv ntes.
Guo et al. Ua tiav qhov kev sib xyaw ua ke ntawm nano kub thiab graphene. Los ntawm kev hloov kho ntawmsib xyaw ua ke, ib lub tshuab ntsuas hluav taws xob isoniazid tshiab tau tsim. Lub tshuab ntsuas hluav taws xob qhia tau tias muaj qhov txwv zoo ntawm kev ntes thiab kev rhiab heev hauv kev ntes isoniazid.
