Sonke siyawazi amarobhothi ahlome ngezingalo ezihambayo.Bahlala phansi efektri, benze umsebenzi wemishini, futhi bangahlelwa.Irobhothi elilodwa lingasetshenziselwa imisebenzi eminingi.
Izimiso ezincane ezithutha amanani amancane oketshezi ngama-capillary azacile bezilokhu zinenani elincane kulawa marobhothi kuze kube namuhla.Ithuthukiswe abacwaningi njengesengezo sokuhlaziywa kwaselabhorethri, amasistimu anjalo aziwa ngokuthi ama-microfluidics noma ama-lab-on-a-chips futhi ngokuvamile asebenzisa amaphampu angaphandle ukuze ahambise uketshezi ku-chip.Kuze kube manje, amasistimu anjalo bekunzima ukuwenza ngokuzenzakalelayo, futhi ama-chips kufanele adizayinwe futhi akhiqizwe ukuze a-odwe ngohlelo ngalunye oluthile.
Ososayensi abaholwa uprofesa we-ETH uDaniel Ahmed manje sebehlanganisa amarobhothi avamile nama-microfluidics.Bakhe umshini osebenzisa i-ultrasound futhi ongaxhunywa engalweni yerobhothi.Ilungele uhla olubanzi lwemisebenzi kuzinhlelo zokusebenza ze-microrobotics kanye ne-microfluidics futhi ingasetshenziswa ukwenza izinhlelo ezinjalo ngokuzenzakalela.Ososayensi babika inqubekelaphambili ku-Nature Communications.
Lolu cingo luqukethe inaliti yengilazi encanyana, ecijile kanye ne-piezoelectric transducer eyenza inaliti inyakaze.Ama-transducer afanayo asetshenziswa kuzipikha, izithombe ze-ultrasound, namathuluzi wamazinyo angochwepheshe.Abacwaningi be-ETH bangashintsha imvamisa yokudlidliza yezinaliti zengilazi.Ngokucwilisa inaliti oketshezini, bakha iphethini enezinhlangothi ezintathu zama-swirls amaningi.Njengoba le modi incike ku-oscillation frequency, ingalawulwa ngendlela efanele.
Abacwaningi bangayisebenzisa ukuze babonise izinhlelo zokusebenza ezihlukahlukene.Okokuqala, babekwazi ukuhlanganisa amaconsi amancane oketshezi olune-viscous.UProfesa Ahmed uyachaza: “Lapho lolu ketshezi lune-viscous ngokwengeziwe, kuba nzima nakakhulu ukuluxuba."Kodwa-ke, indlela yethu iyaphumelela kulokhu ngoba ayigcini nje ngokusivumela ukuthi sakhe i-vortex eyodwa, kodwa futhi ixuba kahle uketshezi sisebenzisa amaphethini ayinkimbinkimbi e-3D akhiwe ama-vortices amaningi aqinile."
Okwesibili, ososayensi bakwazi ukupompa uketshezi ngohlelo lwe-microchannel ngokwenza amaphethini athile e-vortex nokubeka izinaliti zengilazi ezi-oscillating eduze kwezindonga zesiteshi.
Okwesithathu, bakwazi ukuthwebula izinhlayiya ezinhle ezikhona oketshezini besebenzisa idivayisi ye-robotic acoustic.Lokhu kusebenza ngoba ubukhulu bezinhlayiyana bunquma ukuthi isabela kanjani kumaza omsindo.Izinhlayiya ezinkulu ngokuqhathaniswa ziya enalithini yengilazi ezungezayo, lapho zinqwabelana khona.Abacwaningi babonise ukuthi le ndlela ingabamba kanjani izinhlayiya zemvelo engaphili kuphela, kodwa nemibungu yezinhlanzi.Bakholelwa ukuthi kufanele futhi ibambe amaseli ebhayoloji oketshezini.“Esikhathini esidlule, ukuxhaphaza izinhlayiya ezincane ezinhlangothini ezintathu bekulokhu kuyinselele.Ingalo yethu encane eyirobhothi yenza lokhu kube lula,” kusho u-Ahmed.
"Kuze kube manje, intuthuko ekusetshenzisweni okukhulu kwamarobhothi avamile kanye nama-microfluidics yenziwe ngokuhlukana," kusho u-Ahmed."Umsebenzi wethu usiza ukuhlanganisa lezi zindlela ezimbili."Idivayisi eyodwa, ehlelwe kahle, ingaphatha imisebenzi eminingi."Ukuxuba nokumpompa uketshezi nokubamba izinhlayiya, singakwenza konke ngomshini owodwa," kusho u-Ahmed.Lokhu kusho ukuthi ama-microfluidic chips akusasa ngeke esadinga ukuklanywa ngokwezifiso kuhlelo lokusebenza ngalunye.Abacwaningi bese bethemba ukuhlanganisa izinaliti eziningi zengilazi ukuze bakhe amaphethini e-vortex ayinkimbinkimbi oketshezini.
Ngaphezu kokuhlaziya ilabhorethri, u-Ahmed angacabanga okunye ukusetshenziswa kwe-micromanipulator, njengokuhlela izinto ezincane.Mhlawumbe isandla singasetshenziswa futhi ku-biotechnology njengendlela yokwethula i-DNA kumangqamuzana ngamanye.Ekugcineni zingasetshenziselwa ukukhiqiza okungeziwe kanye nokuphrinta kwe-3D.
