Iqela laseMelika liphakamisa indlela entsha yokutsala i-microdisk landlers

Iqela lophando oludibeneyo elivela kwiSikolo sezoNyango laseHarvard (HMS) kunye neMit Jikelele ithe yafumana ukungcolisa iziphumo ze-microphotoning, esenza umthombo we-nanophotonics kunye ne-biodicine "ethembisayo."

(Iziphumo ze-Microdisk Laser inokuhlengahlengiswa yindlela ye-PEC ye-PEC

Kwimimandla yeI-Nanophotonicskunye ne-biodicine, microdiski-landlerskwaye i-nanodisk Lasers sele ithembisaImithombo yokukhanyakunye ne-prooes. Kwizicelo ezininzi ezifana no-On-Chip Photoniic Unxibelelwano, kwi-chip bialing, imvakalelo ye-biechemical, kunye ne-Poton yoLwazi, kufuneka zifezekise imveliso ye-irser kunye nokuchaneka kwebhendi ye-Ultra. Nangona kunjalo, ihlala ilucelomngeni ukwenza i-microdk kunye ne-nanodisk Lasers yale ntetho ichanekileyo. Iinkqubo ezikhoyo zeNanofabriction Yazisa ukungahlekisi kobubanzi be-disc, eyenza ukuba kube nzima ukufumana i-lavelength ye-serser kunye nemveliso.I-Optoectronity yonyangoIphuhlise ubuchule be-opchimical ye-opchimical ye-opchimical ye-opchimical (i-PEC) encedayo ukuba ihambe ngokuchanekileyo i-laser ye-microdk ye-microdisks nge-subnanometer ichanekile. Umsebenzi upapashwe kwijenali Astonics.

Ifoto yokufota
Ngokweengxelo, indlela entsha yeqela ivumela ukuveliswa kwee-leards zediski ezincinci kunye ne-nanodisk Laser ngokulungiselela ngokuchanekileyo, i-Emisted SAVERTS. Isitshixo solu phawu kukusetyenziswa kwe-Pec Etchting, ebonelela ngendlela efanelekileyo neyinto ebonakalayo yokufumana i-wavelength ye-microdisc laser. Kwezi ziphumo zilapha ngasentla, iqela eliyifumene ngempumelelo i-Indim Gallium Arsheside phospheshord phodisks egutyungelwe yi-silica kwi-Insphoside yeKholam ye-Indim phosphide. Emva koko bafaka i-laser ye-laser wavelevele le microdisks ngokuchanekileyo kwixabiso elimiselweyo ngokwenza i-fotosing ye-fotosing kwisisombululo esibi sesalfuric acid.
Bakwaphanda neendlela kunye namandla e-ethocchemical yefoto (i-PEC). Okokugqibela, bagqithisela i-javenched-tuned microdisk ilurgy kwi-polydimesloxane ukuba ivelise izibonelelo ezizimeleyo, ezodwa ze-tser ared kunye ne-laser eyahlukeneyo ye-laser. I-microdisk ekhuphisiweyo ibonisa i-bandwidth ye-ultra ender yokukhupha i-laser, kunye nei-laserkwikholamu engaphantsi kwe-0.6 NM kunye ne-paricle ekhethekileyo engaphantsi kwe-1.5 NM.

Ukuvula ucango kwizicelo ze-biomedical
Oku kubangela ukuba kuvuleke umnyango kwizicelo ezininzi zeNanophotonics ezininzi kunye nezicelo zebhayimu. Umzekelo, iilebhu ze-microdks ze-physisk zinokusebenza njenge-biomes ye-tentelocal ye-biological ye-biomarks kwi-bimomars ekhoyo kunye ne-orts i-bieorores, i-Dluoresces, enamachaphaza amantshontsho, enamachaphaza amantshontsho aphezulu. Ke, zimbalwa kuphela iifowuni ezichaziweyo zinokubizwa ngexesha elinye. Ngokwahlukileyo, i-band ye-ultra emxinwa yokukhanyisela i-microdisk lase-microdisk Laser iya kuba nakho ukukhangela iintlobo zeseli ezininzi ngaxeshanye.
Eli qela lavavanywa kwaye libonisa ngempumelelo i-microdisk ye-microdisk yase-microdisk yase-Microdisk yase-biomaskers, ebasebenzisa ukuba ifayili ifakwe iilebhu eziqhelekileyo ze-MCF10A. Ngokukhutshwa kwabo i-ultra-ilrand, ezi zilopha zinokubakho ngokuguqukayo, ukusebenzisa ubuchwephesha be-biomedical kunye ne-binsodnalical kunye ne-cytometnamic icinga, kwaye kuhlalutyo lwe-cetometnamic, kunye nohlalutyo lwe-cetometnamic, kunye nohlalutyo lwe-cetometnamo. Itekhnoloji esekwe kwi-Pec Etching iphawula inkqubela phambili kwi-microdk lars. I-screaulif yendlela, kunye nokuchaneka kwayo okungafikeleli, kuvula amathuba amatsha okusetyenziswa kwezicelo ezingenabantu kwii-nanophotonics nakwiizixhobo ze-biomedical, kunye neemolekyuli ezithile zeseli.
