O se biosensor microRNA (miRNA) sili ona maaleale o loʻo faʻaaogaina le ruthenium oxide nanoparticle (RuO (2) NP) -na amataina le polymerization o le 3,3'-dimethoxybenzidine (DB) ma le miRNA-modeled deposition o se poly insulating (3,3'-dimethoxybenzidine) (PDB) ata tifaga o loʻo faʻamatalaina i lenei galuega.O le biosensor na faia i se monolayer fefiloi o oligonucleotide capture probes (CPs) ma le 4-mercaptoaniline i luga o se eletise auro.I le mae'a ai o le tu'ufa'atasia ma le RuO(2) NP-tagged target miRNA, o le fa'afefiloi o le DB/H(2)O(2) i le pH 5.0 0.10 M acetate buffer sa fa'aogaina i le biosensor.O le RuO(2) NPs o loʻo avea ma faʻavae polymerization / faʻamalosi mo le polymerization o le DB.Ma o le hybridized anionic miRNA strands ma free CPs e fai ma faʻataʻitaʻiga, e taʻitaʻia ai le teuina o le PDB.O le aofaʻi o le PDB na tuʻuina ma lona malosi faʻapipiʻi e fesoʻotaʻi saʻo i le faʻatonuga o le miRNA sini i le vaifofo.O su'esu'ega fa'ata'ita'iga fa'aeletise fa'asao na fa'aalia ai o se feso'ota'iga tau-fa'aliliuga fa'asagatau-fa'asa'o mai le 6 .0 fM i le 2.0 pM na maua i le mae'a ai o le 60 min o le fa'a'ofuina i le paluga DB/H(2)O(2).E le'i iai se fa'asoso'oso'oga i le va o le mua'i-miRNA ma le miRNA matua ma e la'ititi fo'i le fa'asoso'o fa'atasi i tagata o le aiga o le miRNA e feso'ota'i vavalalata e o'o lava ile tulaga e tasi e le fetaui.O lenei biosensor fa'avae impedance e ofoina atu se mea manaia mo fa'amatalaga fa'amatalaga miRNA ma e mafai ona mafai ai ona fa'atupuina le fa'aogaina o le miRNA fa'apipi'i feavea'i tele.
