Lub vev xaib no yog ua haujlwm los ntawm kev lag luam lossis kev lag luam uas muaj los ntawm Informa PLC thiab txhua qhov kev cai lij choj nyob nrog lawv.Informa PLC lub chaw ua haujlwm sau npe yog 5 Howick Place, London SW1P 1WG.Sau npe hauv England thiab Wales.ib 8860726.
Pab pawg kws tshawb fawb Cal Tech coj los ntawm Wei Gao, tus xibfwb ntawm biomedical engineering, tau tsim cov khoom siv hluav taws xob uas saib xyuas cov qib metabolites thiab cov as-ham hauv tib neeg cov ntshav los ntawm kev txheeb xyuas lawv cov hws.Yav dhau los hws sensors feem ntau tsom cov tebchaw uas tshwm sim hauv cov ntsiab lus siab, xws li electrolytes, qabzib, thiab lactate.Qhov tshiab no yog qhov rhiab dua thiab pom cov hws sib txuas ntawm qhov qis dua.Nws kuj yog ib qho yooj yim rau kev tsim khoom thiab tuaj yeem ua ntau yam.
Pab pawg lub hom phiaj yog lub ntsuas ntsuas uas tso cai rau cov kws kho mob tsis tu ncua saib xyuas cov neeg mob uas muaj mob xws li kab mob plawv, ntshav qab zib mellitus, thiab kab mob raum, tag nrho cov no tso cov khoom noj tsis zoo lossis cov metabolites hauv cov hlab ntsha.Cov neeg mob yuav zoo dua yog tias lawv tus kws kho mob paub ntau ntxiv txog lawv tus kheej tej yam kev mob thiab txoj kev no zam kev sim uas yuav tsum tau koob thiab kuaj ntshav.
†œCov khoom siv hws hnav zoo li no tuaj yeem ua tau sai, tsis tu ncua, thiab tsis cuam tshuam txog kev hloov pauv hauv kev noj qab haus huv ntawm qib molecular,' Gao hais.“Lawv tuaj yeem ua tus kheej saib xyuas, kuaj pom ntxov, thiab kev cuam tshuam raws sijhawm.â€
Lub sensor tso siab rau microfluidics uas tswj cov kua dej me me, feem ntau los ntawm cov channel tsawg dua li ib feem peb ntawm ib millimeter dav.Microfluidics yog qhov zoo tagnrho rau daim ntawv thov vim tias lawv txo qis kev cuam tshuam ntawm hws evaporation thiab kev sib kis ntawm daim tawv nqaij ntawm qhov tseeb sensor.Raws li cov hws tshiab nkag los ntawm lub sensor's microchannels, nws ntsuas qhov muaj pes tsawg leeg ntawm hws thiab ntes cov kev hloov pauv hauv cov ntsiab lus raws sijhawm.
Txog rau tam sim no, Gao thiab nws cov npoj yaig hais tias, microfluidic-based wearable sensors feem ntau yog tsim nrog lithography-evaporation mus kom ze, uas yuav tsum muaj cov txheej txheem nyuaj thiab kim.Nws pab neeg tau xaiv los ua nws cov biosensors tawm ntawm graphene, ib daim ntawv zoo li carbon.Ob lub graphene-raws li sensors thiab microfluidics channel yog tsim los ntawm engraving cov ntawv yas nrog cov pa roj carbon dioxide laser, ib qho cuab yeej muaj ntau rau cov neeg nyiam ua haujlwm hauv tsev.
Pab neeg tshawb fawb tau tsim nws lub sensor los ntsuas qhov ua pa thiab lub plawv dhia, ntxiv rau qib uric acid thiab tyrosine.Tyrosine tau raug xaiv vim nws tuaj yeem yog qhov qhia txog kev mob metabolic, kab mob siab, kev noj zaub mov tsis zoo, thiab cov mob neuropsychiatric.Uric acid tau raug xaiv vim tias, ntawm qib siab, nws cuam tshuam nrog gout, mob sib koom ua ke uas tau nce thoob ntiaj teb.Gout tshwm sim thaum qib siab ntawm uric acid hauv lub cev pib crystallizing hauv cov pob qij txha, tshwj xeeb tshaj yog cov ko taw, ua rau khaus thiab mob.
Txhawm rau pom tias cov sensors ua tau zoo npaum li cas, cov kws tshawb fawb tau sim nws ntawm cov tib neeg noj qab haus huv thiab cov neeg mob.Txhawm rau txheeb xyuas cov hws tyrosine qib uas cuam tshuam los ntawm tus neeg lub cev muaj zog, lawv tau siv ob pawg neeg: cov neeg ncaws pob tau txais kev cob qhia thiab cov neeg muaj zog nruab nrab.Raws li kev cia siab, cov sensors pom cov qib qis ntawm tyrosine hauv cov neeg ncaws pob tawm hws.Txhawm rau txheeb xyuas cov qib uric acid, cov kws tshawb fawb tau soj ntsuam cov hws ntawm ib pab pawg neeg noj qab haus huv uas tau yoo mov, thiab tom qab cov neeg kawm tau noj ib pluag mov nplua nuj nyob rau hauv purines's nyob rau hauv cov zaub mov uas metabolized rau hauv uric acid.Qhov ntsuas tau pom tias qib uric acid nce tom qab noj mov.Gao's pab neeg tau ua qhov kev sim zoo sib xws nrog cov neeg mob gout.Lub sensor pom tias lawv cov qib uric acid ntau dua li cov neeg noj qab haus huv.
Txhawm rau kuaj xyuas qhov tseeb ntawm cov sensors, cov kws tshawb fawb tau kos thiab kuaj ntshav kuaj los ntawm cov neeg mob gout thiab cov neeg noj qab haus huv.Cov sensors ntsuas cov qib uric acid muaj kev cuam tshuam nrog cov qib ntawm nws hauv lawv cov ntshav.
Gao hais tias lub siab rhiab heev ntawm cov sensors, nrog rau qhov yooj yim uas lawv tuaj yeem tsim tau, txhais tau tias lawv tuaj yeem siv los ntawm cov neeg mob hauv tsev los saib xyuas cov mob xws li gout, ntshav qab zib, thiab kab mob plawv.Muaj cov ntaub ntawv raug raws sijhawm txog lawv txoj kev noj qab haus huv tuaj yeem ua rau cov neeg mob kho lawv cov qib tshuaj thiab noj zaub mov raws li qhov xav tau.
