I hangaia he aptasensor whaihua i whakamahia ai te graphene oxide (GO) hei tohu mo te whakangao hiko hiko hiko me te whakaputa tohu hiko (ECL).I hangaia te aptasensor na roto i te whakahiato-whaiaro i te tirotiro ECL o te adenosine triphosphate herea aptamer (ABA) kua tohua ki te Ru complex (Ru(bpy)3(2+) derivatives) ki runga i te mata o te koura nanoparticle (AuNP) waro karaihe whakarereke. hiko (GCE).Ko te ABA kua kore e nekehia ki runga i te AuNP kua whakarereketia te GCE ka kaha te whakauru i a GO na te kaha o te π-π i waenga i te ABA me te graphene oxide;Ko te whakakorenga ECL o te matatini Ru ka puta na te whakawhiti hiko me te whakawhiti irahiko, me te pikinga nui o te aukati whakawhiti irahiko (Ret) o te hiko.Ahakoa kei te aroaro o te adenosine triphosphate (ATP), he pai ake te ABA ki te hanga i nga ABA-ATP bioaffinity complexes, he ngoikore te hononga ki te graphene oxide me te pupuri i te graphene oxide mai i te mata hiko, na reira ka taea te whakanui i te tohu ECL, a i te taha o te hekenga o te Ret.Na te kaha o te whakakao ECL, te hanganga ahurei, me nga taonga hiko o te graphene oxide, ko te Ret me te ECL te kaha ki te aro ki te logarithm o te kukū ATP he ahorangi i roto i te whānuitanga whanui mai i te 10 pM ki te 10 nM me te rohenga tino iti o te 6.7. pM ki te 4.8 pm, ia.Ko te aptasensor i whakaarohia he tino pai te whakaputa, te pumau, me te tino whiriwhiringa, a ka taea te wehe i te ATP mai i ona analogues.Ko te mea nui ake, ko tenei rautaki aptasensor ECL pai i runga i a GO e mahi ana hei tohu hiko me te tohu tohu ECL he whanui noa, ka ngawari ki te toro atu ki etahi atu kaupapa here koiora.
