Saiti ino inoshandiswa nebhizinesi kana mabhizinesi ane Informa PLC uye ese ane kodzero anogara navo.Hofisi yakanyoreswa yeInforma PLC ndeye 5 Howick Nzvimbo, London SW1P 1WG.Yakanyoreswa muEngland neWales.Nhamba 8860726.
Chikwata cheCal Tech muongorori chinotungamirwa naWei Gao, purofesa we biomedical engineering, vakagadzira sensor inopfekwa inotarisisa mazinga emametabolites uye kudya muropa remunhu nekuongorora ziya ravo.Masensa ekare edikita ainyanya kutariswa makomisheni anoonekwa mune yakanyanya kuwanda, senge electrolytes, glucose, uye lactate.Ichi chitsva chinonzwa zvakanyanya uye chinoona makomba edikita pakadzika zvakanyanya.Izvo zvakare zviri nyore kugadzira uye zvinogona kugadzirwa-zhinji.
Chinangwa chechikwata inzwa inoita kuti vanachiremba varambe vachitarisa mamiriro evarwere vane zvirwere zvakadai sechirwere chemwoyo, chirwere cheshuga, uye chirwere chetsvo, izvo zvose zvinoisa mazinga asina kunaka ezvokudya kana metabolites muropa.Varwere vangave nani kana chiremba wavo aiziva zvakawanda nezvemamiriro avo ega uye nzira iyi inodzivirira bvunzo dzinoda tsono nekutorwa kweropa.
“Masensa anopfekwa edikita anogona kukurumidza, kuenderera, uye nekusavhiringidza kuchinja kwehutano pamazinga emamorekuru,†anodaro Gao.“Vanogona kuita kuti kutariswa kwemunhu, kuongororwa nekukasika, uye kupindira panguva yakakodzera.â
Iyo sensor inotsamira pane microfluidics iyo inoshandura zvidiki zvinwiwa, kazhinji kuburikidza nematanho asingasviki chikamu chechina chemirimita muhupamhi.Microfluidics yakanyatsokodzera application nekuti inodzikisira pesvedzero yekubuda ziya uye kusvibiswa kweganda pakurongeka kwe sensor.Sezvo dikita richangobva kupihwa richiyerera kuburikidza ne sensorâ € ™s microchannels, inoyera chaizvo kuumbwa kweziya uye inotora shanduko mukudzika nekufamba kwenguva.
Kusvika ikozvino, Gao nevamwe vake vanoti, microfluidic-based wearable sensors yainyanya kugadzirwa ine lithography-evaporation nzira, iyo inoda yakaoma uye inodhura maitiro ekugadzira.Chikwata chake chakasarudza kugadzira mabiosensors ayo kubva mugraphene, pepa-rakafanana nekabhoni fomu.Ose ari maviri magraphene-based sensors uye microfluidics chiteshi anogadzirwa nekunyora mapepa epurasitiki necarbon dioxide laser, chishandiso chakajairika kuti chiwanikwe kune vanoita zvekumba.
Chikwata chekutsvagisa chakagadzira sensor yayo kuyerawo kufema uye mwero wemoyo, kuwedzera kune mazinga euric acid uye tyrosine.Tyrosine yakasarudzwa nekuti inogona kuve chiratidzo chekusagadzikana kwemetabolic, chirwere chechiropa, kusagadzikana kwekudya, uye neuropsychiatric mamiriro.Uric acid yakasarudzwa nokuti, pamazinga akakwirira, inosanganiswa negout, chirwere chinorwadza chejoini chiri kuwedzera pasi rose.Gout inoitika apo huwandu hweuric acid mumuviri hunotanga kupenya mumajoini, kunyanya iwo etsoka, zvichikonzera kushatirwa uye kuzvimba.
Kuti vaone kuti ma sensors akaita sei zvakanaka, vaongorori vakaiedza pavanhu vane hutano uye nevarwere.Kuti vatarise mazinga e sweat tyrosine ayo anokonzerwa nekusimba kwemunhu mumuviri, vakashandisa mapoka maviri evanhu: vatambi vakadzidziswa uye vanhu veavhareji yekusimba.Sezvaitarisirwa, masensa airatidza akaderera mazinga e tyrosine mune yevatambi ziya.Kuti vatarise mazinga euric acid, vaongorori vakatarisa ziya reboka revanhu vane hutano vaitsanya, uye zvakare mushure mekunge vanhu vadya chikafu chakapfuma mupurines - macompound muchikafu anogadzikiswa kuita uric acid.Iyo sensor yakaratidza uric acid mazinga achikwira mushure mekudya.Chikwata cheGao chakaita bvunzo dzakafanana nevarwere vegout.Iyo sensor yakaratidza iwo uric acid mazinga aive akakwira zvakanyanya kupfuura aya evanhu vane hutano.
Kuti utarise huchokwadi hwemasensa, vaongorori vakadhirowa nekutarisa masampula eropa kubva kuvarwere vegout uye zvidzidzo zvine hutano.Iwo ma sensors’ zviyero zvemazinga euric acid ane hukama zvakanyanya nemazinga ayo muropa ravo.
Gao anoti kunzwisiswa kwakanyanya kwemasensa, pamwe nekureruka kwaanogona kugadzirwa nawo, zvinoreva kuti anogona kupedzisira ashandiswa nevarwere kumba kutarisa mamiriro akaita segout, chirwere cheshuga, uye chirwere chemoyo.Kuve neruzivo rwechokwadi rwenguva-chaiyo nezvehutano hwavo hunogona kutorega varwere vachigadzirisa mazinga emishonga yavo uye kudya sezvinodiwa.
