Alaabta

Agabka graphene ayaa aad caan uga ah dhanka biosensing-ka taasoo ay ugu wacan tahay sifooyinkooda gaarka ah.Si kastaba ha ahaatee, kooxaha ka kooban ogsijiinta ayaa la og yahay in ay ka dhex jiraan walxaha garaafka la xiriira.Kooxahani waxay saameeyaan sifooyinka korantada ee alaabta graphene sidaas darteed waxay saameeyaan waxqabadka dareenka ee electrodes-ka ku salaysan graphene marka loo isticmaalo in lagu ogaado redox firfircoon biomarkers.Saamiga kaarboon/ogsajiin (C/O) si wanaagsan loo qeexay ayaa la heli karaa marka la adeegsado awoodaha dhimista kala duwan ee filimada graphene oxide (GO) si loo xakameeyo ka-saarista dib-u-dhiska shaqada oksijiinta firfircoon.Halkan, waxaan ku tusineynaa in xakamaynta saxda ah ee shaqeynta oksijiinta ee filimada graphene oxide ay u ogolaato hagaajinta awoodaha biosensing ee korantada ee falanqaynta laba biomarkers, uric acid iyo ascorbic acid, iyo sidoo kale laba saldhig oo DNA ah, guanine iyo adenine.Labada dabeecadood ee catalytic iyo dareenka hoos u dhaca filimka GO ee electrodes (ERGOs) ayaa lagu qiimeeyaa iyada oo la cabbirayo awoodda oksaydhka iyo hadda ugu sarreeya, siday u kala horreeyaan.Waxaan muujineynaa in biomarker kastaa uu u baahan yahay xaalado kala duwan oo ugu wanaagsan kuwaas oo si fudud loo waafajin karo iyadoo la beddelayo daawaynta hore ee korantada ee dareenka GO filimka.
