Chiyambi cha Lateral Flow Rapid Test Diagnostics

Ma lateral flow assays (LFAs) ndi osavuta kugwiritsa ntchito, zida zowunikira zomwe zimatha kuyesa ma biomarker mu zitsanzo monga malovu, magazi, mkodzo, ndi chakudya.Mayesowa ali ndi maubwino angapo kuposa matekinoloje ena ozindikira matenda kuphatikiza:

❆ Kuphweka: Kuphweka kogwiritsa ntchito mayeserowa sikungafanane - ingowonjezerani madontho ochepa pa doko lachitsanzo ndikuwerenga zotsatira zanu ndi maso mphindi zingapo pambuyo pake.
❆ Zachuma: Mayesowa ndi otsika mtengo - nthawi zambiri amakhala osakwana dola imodzi pa mayeso opangidwa pamlingo uliwonse.
❆ Yamphamvu: Mayesowa amatha kusungidwa pamalo otentha komanso kukhala ndi alumali wazaka zambiri.

Ma mabiliyoni a mayeso amapangidwa chaka chilichonse kuti azindikire matenda opatsirana pogonana, matenda oyambitsidwa ndi udzudzu, chifuwa chachikulu, chiwindi, kuyezetsa mimba ndi chonde, zolembera zamtima, kuyezetsa cholesterol / lipid, mankhwala osokoneza bongo, kuwunika kwa ziweto, komanso chitetezo cha chakudya, pakati pawo. ena.
LFA imapangidwa ndi chitsanzo cha pad, conjugate pad, nitrocellulose strip yomwe ili ndi mizere yoyesera ndi yolamulira, ndi pad wicking.Chigawo chilichonse chimadutsana ndi osachepera 1-2 mm zomwe zimapangitsa kuti capillary isayende bwino.

Kuti mugwiritse ntchito chipangizochi, chitsanzo chamadzimadzi monga magazi, seramu, plasma, mkodzo, malovu, kapena zolimba zosungunuka, zimawonjezedwa mwachindunji papepala lachitsanzo ndipo ndi loipa kudzera mu chipangizo chotsatira.Chitsanzo pad neutralizes chitsanzo ndi zosefera zosafunikira monga maselo ofiira a magazi.Zitsanzozi zimatha kuyenda mopanda malire kupita ku conjugate pad yomwe ili ndi ma nanoparticles amitundu yamitundu kapena fulorosenti omwe ali ndi antibody pamwamba pake.Madzi akafika pa conjugate pad, nanoparticles zouma izi zimatulutsidwa ndikusakaniza ndi chitsanzo.Ngati pali owunikira omwe akuwaganizira pachitsanzo omwe antibody amazindikira, awa amalumikizana ndi antibody.Ma nanoparticles omwe amamangidwa ndi analyte ndiye amayenda kudzera mu nembanemba ya nitrocellulose ndikudutsa mizere imodzi kapena zingapo zoyeserera ndi mzere wowongolera.Mzere woyesera (wotchedwa T mu chithunzi pamwambapa) ndiwomwe umawerengedwa kwambiri pofufuza matenda ndipo uli ndi mapuloteni osasunthika omwe amatha kumanga nanoparticle kuti apange chizindikiro chomwe chikugwirizana ndi kukhalapo kwa analyte mu chitsanzo.Madzi amadzimadzi amapitilira kudutsa pamzerewu mpaka kukafika pamzere wowongolera.Mzere wowongolera (wotchedwa C pachithunzi pamwambapa) uli ndi ma affinity ligands omwe amamanga nanoparticle conjugate ndi kapena popanda analyte yomwe ilipo mu njira yothetsera kutsimikizira kuti kuyesa kukugwira ntchito bwino.Pambuyo pa mzere wolamulira, madzimadzi amalowa muzitsulo zowonongeka zomwe zimafunika kuti zitenge madzi onse a chitsanzo kuti zitsimikizire kuti pali kuyenda kosasinthasintha kudutsa mizere yoyesera ndi kulamulira.M'mayeso ena, chotchingira chothamangitsa chimayikidwa pa doko lachitsanzo pambuyo poyambitsa zitsanzo kuti zitsimikizire kuti zitsanzo zonse zatumizidwa kudutsa mzerewo.Zitsanzo zonse zikadutsa mizere yoyeserera ndikuwongolera, kuyesa kwatha ndipo wogwiritsa ntchito amatha kuwerenga zotsatira.

Nthawi yowunikira imadalira mtundu wa nembanemba yomwe imagwiritsidwa ntchito poyesa lateral flow assay (zokulirapo zimayenda mwachangu koma nthawi zambiri sizimva bwino) ndipo nthawi zambiri zimatha pasanathe mphindi 15.
