Sonke siqhelene neerobhothi ezineengalo ezishukumayo.Bahlala kumgangatho womzi-mveliso, benze umsebenzi woomatshini, yaye banokucwangciswa.Irobhothi enye ingasetyenziselwa imisebenzi emininzi.
Iinkqubo ezincinci ezithutha izixa ezingabalulekanga zolwelo ngeecapillaries ezibhityileyo bezingeloxabiso elincinane kwezo robhothi kude kube namhlanje.Iphuhliswe ngabaphandi njengoncediso kuhlalutyo lwelabhoratri, ezo nkqubo zaziwa njenge-microfluidics okanye i-lab-on-a-chips kwaye ngokuqhelekileyo zisebenzisa iimpompo zangaphandle ukuhambisa ulwelo kwitshiphu.Ukuza kuthi ga ngoku, ezo nkqubo bekunzima ukuzenzela, kwaye iitshiphusi kufuneka ziyilwe kwaye zenziwe ukuodola kwisicelo ngasinye.
Izazinzulu ezikhokelwa ngunjingalwazi we-ETH uDaniel Ahmed ngoku zidibanisa iirobhothi eziqhelekileyo kunye ne-microfluidics.Baye benza isixhobo esisebenzisa iultrasound yaye sinokuqhotyoshelwa kwingalo yerobhothi.Ilungele uluhlu olubanzi lwemisebenzi kwi-microrobotics kunye ne-microfluidics izicelo kwaye ingasetyenziselwa ukuzenzekelayo izicelo ezinjalo.Izazinzulu zinika ingxelo yenkqubela phambili kuNxibelelwano lweNdalo.
Esi sixhobo sinenaliti ecekethekileyo, etsolileyo yeglasi kunye ne-piezoelectric transducer ebangela ukuba inaliti ingcangcazele.Iitransducer ezifanayo zisetyenziswa kwizandisi-lizwi, umfanekiso weultrasound, kunye nezixhobo zobuchwephesha bamazinyo.Abaphandi be-ETH banokutshintsha i-vibration frequency yeenaliti zeglasi.Ngokuthi nkxu inaliti kulwelo, benza ipateni enemigangatho emithathu yee-swirls ezininzi.Ekubeni le modi ixhomekeke kwi-oscillation frequency, inokulawulwa ngokufanelekileyo.
Abaphandi banokuyisebenzisa ukubonisa izicelo ezahlukeneyo.Okokuqala, babekwazi ukuxuba amathontsi amancinane olwelo olubonakala kakhulu.Unjingalwazi Ahmed uthi: “Okukhona ulwelo lubonakala ngakumbi, kokukhona kuba nzima ukuluxuba."Nangona kunjalo, indlela yethu iyagqwesa koku kuba ayivumeli kuphela ukuba senze i-vortex enye, kodwa ikwaxuba ngokufanelekileyo ulwelo kusetyenziswa iipateni ezintsonkothileyo ze-3D ezenziwe ngeevortis ezininzi ezinamandla."
Okwesibini, izazinzulu ziye zakwazi ukupompa ulwelo ngenkqubo ye-microchannel ngokwenza iipateni ezithile ze-vortex kunye nokubeka iinaliti zeglasi ezikufutshane kwiindonga zetshaneli.
Okwesithathu, baye bakwazi ukubamba amasuntswana amahle akhoyo kulwelo besebenzisa isixhobo se-robotic acoustic.Oku kusebenza ngenxa yokuba ubukhulu besuntswana bumisela indlela elisabela ngayo kumaza esandi.Amasuntswana amakhulu ahamba aye kwinaliti yeglasi ejikelezayo, apho aqokelelana khona.Abaphandi babonise indlela le ndlela yokubamba kungekuphela nje amasuntswana endalo engaphiliyo, kodwa kunye neembumba zeentlanzi.Bakholelwa ukuba kufuneka ibambe iiseli zebhayoloji kulwelo.“Kwixesha elidlulileyo, ukwenza amasuntswana amakroskopu kumacala amathathu bekusoloko kulucelomngeni.Ingalo yethu encinci yerobhothi yenza oku kube lula, ”utshilo u-Ahmed.
Ukuza kuthi ga ngoku, ukuqhubela phambili kwizicelo ezinkulu zerobhothi eziqhelekileyo kunye ne-microfluidics zenziwe ngokwahlukeneyo, utshilo u-Ahmed."Umsebenzi wethu unceda ukudibanisa ezi ndlela zimbini."Isixhobo esinye, esicwangciswe kakuhle, siyakwazi ukusingatha imisebenzi emininzi."Ukuxuba kunye nokupompa ulwelo kunye nokubamba amasuntswana, sinokwenza konke ngesixhobo esinye," utshilo u-Ahmed.Oku kuthetha ukuba iitshiphusi ze-microfluidic zangomso azisayi kuphinda zifuneke ukuba ziyilwe ngokwesicelo ngasinye.Abaphandi ke banethemba lokudibanisa iinaliti ezininzi zeglasi ukwenza iipateni ezintsonkothileyo ze-vortex kulwelo.
Ukongeza kuhlalutyo lwebhubhoratri, u-Ahmed unokucinga okunye usetyenziso lwe-micromanipulator, njengokuhlela izinto ezincinci.Mhlawumbi isandla sinokusetyenziswa kwi-biotechnology njengendlela yokwazisa i-DNA kwiiseli nganye.Ekugqibeleni zinokusetyenziselwa ukuvelisa okongeziweyo kunye noshicilelo lwe-3D.
