Timagwiritsa ntchito makeke kuti tikulitse luso lanu.Mukapitiliza kusakatula tsamba ili mukuvomera kugwiritsa ntchito makeke.Zambiri.
Posindikiza mu magazini ya Additive Manufacturing, gulu la ofufuza ochokera ku Manipal Institute of Higher Education ku India lipoti la chitukuko cha lens yodzikongoletsera ya 3D yosindikizidwa. zida zachipatala za m'badwo wotsatira.

Ma lens olumikizana nawo nthawi zambiri amagwiritsidwa ntchito kukonza masomphenya ndikukhala ndi mwayi wokhala wosavuta kuvala kuposa magalasi.Kuonjezera apo, ali ndi ntchito zodzikongoletsera, monga momwe anthu ena amawaona kuti ndi okongola kwambiri. mu biomedicine kuti mupange zida zodziwikiratu zomwe sizimawononga komanso zowunikira.
Maphunziro angapo achitika m'derali ndipo zapangidwa zina zatsopano.Mwachitsanzo, Google lens ndi mandala anzeru omwe angagwiritsidwe ntchito kuyang'anira kuchuluka kwa shuga m'misozi ndikupereka chidziwitso chodziwitsa anthu omwe ali ndi matenda a shuga. mayendedwe angayang'anidwe pogwiritsa ntchito zida zanzeru.Zinthu zopangidwa ndi Nanostructured zaphatikizidwa mu nsanja zowonera magalasi anzeru kuti zizigwira ntchito ngati masensa.
Komabe, kugwiritsa ntchito zipangizozi kungakhale kovuta, kulepheretsa chitukuko cha malonda a ma lens okhudzana ndi ma lens.Kuvala ma lens olumikizana kwa nthawi yaitali kungayambitse kusokonezeka, ndipo kumakhala kouma, kumayambitsa mavuto ambiri kwa wovala. zimasokoneza kuphethira kwachilengedwe, zomwe zimapangitsa kuti madzi asasungidwe mokwanira komanso kuwonongeka kwa minofu yofooka ya diso la munthu.
Njira zachikale ndi monga kudonthozera m'maso ndi zotsekera m'maso, zomwe zimapangitsa kuti misozi ikhale ndi madzi m'maso. Njira ziwiri zatsopano zapangidwa m'zaka zaposachedwa.
Mu njira yoyamba, graphene imodzi yokha imagwiritsidwa ntchito pofuna kuchepetsa kutuluka kwa madzi, ngakhale kuti njirayi imalepheretsedwa ndi njira zopangira zovuta.Mu njira yachiwiri, electroosmotic flow imagwiritsiridwa ntchito kusunga lens hydrated, ngakhale kuti njirayi imafuna chitukuko chodalirika cha biocompatible. mabatire.
Ma lens okhudzana ndi chikhalidwe amapangidwa pogwiritsa ntchito makina opangira lathe, kupanga ndi kuponyera njira.Njira zopangira ndi zopota zimakhala ndi phindu la mtengo wapatali, koma zimalepheretsedwa ndi mankhwala ovuta pambuyo pokonza kuti apititse patsogolo kumatira kwa zinthu ku nkhungu. njira yovuta komanso yokwera mtengo yokhala ndi zopinga zamapangidwe.
Kupanga zowonjezera kwatulukira ngati njira yodalirika yopangira njira zopangira ma lens achikhalidwe.Njirazi zimapereka zopindulitsa monga kuchepetsa nthawi, ufulu wochuluka wa mapangidwe, ndi zotsika mtengo.Kusindikiza kwa 3D kwa ma lens ndi zipangizo zowunikira kudakali koyambirira, ndipo kafukufuku wa njirazi zikusowa.Zovuta zimayamba chifukwa cha kutayika kwa mapangidwe ake komanso kusakanikirana kofooka kwapakati pa post-processing.Kuchepetsa kukula kwa sitepe kumapangitsa kuti pakhale mawonekedwe osalala, omwe amachititsa kuti azimatira.
Ngakhale kuti kafukufuku wochulukirapo akuyang'ana pa kugwiritsa ntchito njira zosindikizira za 3D kuti apange ma lens, pali kusowa kwa zokambirana za kupanga nkhungu poyerekeza ndi magalasi okha.Kuphatikiza teknoloji yosindikizira ya 3D ndi njira zopangira miyambo zimapereka zabwino kwambiri padziko lonse lapansi.
Olembawo adagwiritsa ntchito njira yatsopano yosindikizira magalasi odzitchinjiriza a 3D. Choyimira chachikulucho chinapangidwa pogwiritsa ntchito kusindikiza kwa 3D, ndipo chitsanzocho chinapangidwa pogwiritsa ntchito AutoCAD ndi sterolithography, njira yosindikizira ya 3D yodziwika bwino. maziko a arc ndi 8.5 mm. Kukula kwa sitepe popanga ndi 10 µm yokha, kugonjetsa mavuto achikhalidwe ndi ma lens osindikizidwa a 3D.

Madera owoneka bwino a ma lens opangidwa amawongoleredwa atasindikizidwa ndikusinthidwanso pa PDMS, chinthu chofewa cha elastomeric. Njira yomwe imagwiritsidwa ntchito pagawoli ndi njira yofewa ya lithography.Chinthu chachikulu cha magalasi olumikizirana osindikizidwa ndi kukhalapo kwa tinjira tating'onoting'ono mkati mwa kapangidwe kake. , zomwe zimawapatsa mphamvu yodzipangira okha.Kuonjezera apo, lens ili ndi kutumiza kwabwino kwa kuwala.
Olembawo adapeza kuti kusanjikizana kwa kapangidwe kameneko kumawonetsa kukula kwa ma microchannels, okhala ndi njira zazitali zosindikizidwa pakati pa lens ndi zazifupi zazitali m'mphepete mwa mapangidwe osindikizidwa. , kumathandizira kuyenda kwamadzimadzi oyendetsedwa ndi capillary ndikunyowetsa zida zosindikizidwa.
Chifukwa chosowa kukula kwa ma microchannel ndikuwongolera kugawa, ma microchannel okhala ndi ma microchannel odziwika bwino komanso kuchepa kwa masitepe adasindikizidwa pagawo la masters ndikusinthidwanso pa lens yolumikizirana. kuti apewe kutayika kwa kufalikira kwa kuwala.
Olembawo amanena kuti njira yawo yatsopano sikuti imangowonjezera mphamvu yodzikongoletsera ya magalasi osindikizira osindikizidwa, komanso imapereka nsanja ya chitukuko chamtsogolo cha ma lens ogwiritsira ntchito lab-on-a-chip. -Time biomarker discovery applications.Ponseponse, phunziroli limapereka njira yofufuzira yosangalatsa ya tsogolo la ma lens-based biomedical devices.
