Sisebenzisa iikuki ukuphucula amava akho.Ngokuqhubeka ukhangela le sayithi uyavuma ukusebenzisa iikuki.Ingcaciso eyongezelelekileyo.
Ukupapasha kwiphephancwadi i-Additive Manufacturing, iqela labaphandi abavela kwi-Manipal Institute of Higher Education e-Indiya babika ukuphuhliswa kwe-lens yoqhagamshelwano ye-3D eprintiweyo. izixhobo zonyango ezisekelwe kwi-lens yesizukulwana esilandelayo.

Iilensi zoqhagamshelwano zisoloko zisetyenziselwa ukulungisa umbono kwaye zinenzuzo yokuba lula ukunxiba kuneeglasi.Ukongezelela, zinezinto zokuthambisa, njengoko abanye abantu bezifumanisa zithandeka ngakumbi.Ukongezelela kolu setyenziso lwemveli, iilensi zoqhagamshelwano ziye zaphononongwa kwizicelo. kwi-biomedicine ukuphuhlisa izixhobo ze-smart sensing ezingahlaseli kunye ne-point-of-care diagnostics.
Izifundo ezininzi zenziwe kule ndawo kwaye ezinye izinto ezintsha eziphawulekayo ziye zaphuhliswa.Ngokomzekelo, i-lens yeGoogle i-lens yoqhagamshelwano ehlakaniphile engasetyenziselwa ukubeka iliso kwizinga le-glucose kwiinyembezi kunye nokubonelela ngolwazi lokuxilonga kubantu abanesifo sikashukela.Uxinzelelo lwe-intraocular kunye neliso. iintshukumo zinokujongwa kusetyenziswa izixhobo ezihlakaniphileyo.Izinto eziqulethwe yi-Nanostructured zifakwe kwi-smart contact lens-based sensing platforms to act as sensors.
Nangona kunjalo, ukusetyenziswa kwezi zixhobo kunokuba ngumngeni, kuthintele uphuhliso lwezorhwebo lweeplatifomu ezisekelwe kwi-lens.Ukugqoka iilensi zokudibanisa ixesha elide kunokubangela ukungahambi kakuhle, kwaye zivame ukuma, zibangele iingxaki ezingakumbi kulowo unxibileyo. kuphazamisana nenkqubo yokuqhwanyaza kwendalo, okubangela ukugcinwa kwamanzi okwaneleyo kunye nomonakalo kwizicubu ezithambileyo zeliso lomntu.
Iindlela zemveli ziquka ukuhla kwamehlo kunye neeplagi ze-punctal, eziphucula ukuvuselela iinyembezi ukuze kufakwe amanzi emehlweni.Iendlela ezimbini zenoveli ziye zaphuhliswa kwiminyaka yamuva.
Kwindlela yokuqala, i-graphene ene-single-layer isetyenziselwa ukunciphisa ukukhuphuka kwamanzi, nangona le ndlela iphazamiseka ngeendlela eziyinkimbinkimbi zokwenza izinto.Kwindlela yesibini, ukuhamba kwe-electroosmotic kusetyenziselwa ukugcina i-lens i-hydrated, nangona le ndlela idinga ukuphuhliswa kwe-biocompatible ethembekileyo. iibhetri.
Ii-lens zoqhagamshelwano zenziwe ngokuqhelekileyo zisebenzisa i-lathe machining, ukuqulunqa kunye neendlela zokuphosa i-spin.Ienkqubo zokubunjwa kunye ne-spin-casting zineenzuzo ezingabizi kakhulu, kodwa zithintelwa ngonyango oluyinkimbinkimbi emva kokuphucula ukubambelela kwizinto ezibonakalayo kwi-mold surface. inkqubo entsonkothileyo nexabisayo enemiqobo yoyilo.
Imveliso eyongeziweyo iye yavela njengenye indlela ethembisayo kwiindlela zokuvelisa i-lens yendabuko.Obu buchule bunikezela ngeenzuzo ezifana nexesha elincitshisiweyo, inkululeko enkulu yoyilo, kunye neendleko. ezi nkqubo zinqongophele.Imingeni ivela ngokulahleka kweempawu zesakhiwo kunye nokunamathela obuthathaka kwi-interfacial adhesion kwi-post-processing.Ukunciphisa ubungakanani besinyathelo kubangela isakhiwo esilula, esiphucula ukubambelela.
Nangona uphando oluninzi lugxininise ekusetyenzisweni kweendlela zokushicilela ze-3D ukwenza iilensi zoqhagamshelwano, kukho ukungabikho kweengxoxo malunga nokwenza i-molds xa kuthelekiswa ne-lens ngokwabo.Ukudibanisa iteknoloji yokushicilela i-3D kunye neendlela zokuvelisa zendabuko kunika ezona zinto zibalaseleyo zehlabathi.
Ababhali basebenzisa indlela yenoveli kwi-3D yokushicilela iilensi zoqhagamshelwano zokuzimanzisa.Isakhiwo esiphambili senziwe kusetyenziswa ushicilelo lwe-3D, kwaye imodeli yaphuhliswa ngokusebenzisa i-AutoCAD kunye ne-stereolithography, ubuchule obuqhelekileyo bokushicilela i-3D. isiseko se-arc yi-8.5 mm. Ubungakanani besinyathelo kwinkqubo yokuvelisa yi-10 µm kuphela, ukoyisa iingxaki zemveli ngeelensi zoqhagamshelwano eziprintiweyo ze-3D.
IiLensi zoQhagamshelwano ezihlakaniphile
Imimandla ye-optical ye-contact lens eyenziwe igudiswa emva kokuprintwa kwaye iphinda iphindwe kwi-PDMS, i-elastomeric material ethambileyo.Indlela yobugcisa esetyenziswe kweli nyathelo yindlela ye-lithography ethambileyo. , ebanika amandla okuzimanzisa.Ngaphezu koko, i-lens inokuhanjiswa kokukhanya okulungileyo.
Ababhali bafumanisa ukuba isisombululo sobume besakhiwo sichaza imilinganiselo ye-microchannels, kunye neziteshi ezinde eziprintiweyo phakathi kwelensi kunye nobude obufutshane kwimida yezakhiwo eziprintiweyo.Nangona kunjalo, xa ibonakaliswe kwi-oxygen plasma, izakhiwo zaba yi-hydrophilic. , ukuququzelela ukuhamba kwe-capillary-driven fluid kunye nokumanzisa izakhiwo eziprintiweyo.
Ngenxa yokunqongophala kobungakanani be-microchannel kunye nolawulo lokuhambisa, ii-microchannels ezinee-microchannels ezichazwe kakuhle kunye neziphumo ezincitshisiweyo zenyathelo zaprintwa kwi-master structure kwaye emva koko ziphindwe kwi-lens yoqhagamshelwano. ukuthintela ilahleko yokuhanjiswa kokukhanya.
Ababhali bathi indlela yabo entsha ayiphuculi kuphela ikhono lokuzithambisa lelensi zoqhagamshelwano eziprintiweyo, kodwa likwabonelela ngeqonga lophuhliso lwexesha elizayo le-lenses zonxibelelwano ezinikwe i-lab-on-a-chip. -ixesha lezicelo zokufumanisa i-biomarker.Kuko konke, olu pho nonongo lubonelela ngesikhokelo sophando esinomdla kwixesha elizayo lezixhobo ze-biomedical ezisekelwe kwi-lens.
