Nyob rau hauv xyoo tsis ntev los no, txheeb xyuas roj ntsha thiab cov microcitices thiab cov microlicers tau nyiam ntau vim lawv muaj peev xwm nrhiav tau, cov ntaub ntawv kev ruaj ntseg, cov ntaub ntawv kev nyab xeeb thiab kev tawm tsam kev tiv thaiv. Txawm li cas los xij, tsis muaj kev tshawb fawb tau tsom mus tsim lasers siv tshuaj edible. Tsis ntev los no, tus xibfwb Humba Team ntawm Slovenia tau siv cov khoom siv kho kom zoo, thiab tsim cov khoom noj tshiab rau kev saib xyuas kev nyab xeeb khoom noj. Qhov kev tshawb fawb no tau txhim kho cov khoom siv hluav taws xob, kev nyab xeeb thiab cov tshuaj tshiab, thiab muab cov ntawv thov kev tshawb fawb ib puag ncig, chaw ua haujlwm thiab cov ntawv thov biomedical.
Yuav ua li cas ua kom cov Microlasers tau ua li cas?
Lasers feem ntau muaj peb feem: twj tso kua mis, nce nruab nrab, thiab cov kab noj hniav resonity. Qhov nce nruab nrab yog cov xim fluorescent uas muab qhov hloov kho kho qhov muag los ntawm kev tso tawm kev txhawb nqa. Txoj kev tshawb fawb pom tau pom ob hom microcavorities: wreging gallery hom (wgm) thiab fabry-pot (FP) hom. Tus microlas yog nqus los ntawm ib qho teeb pom kev sab nraud, xws li lub ntsej muag pulsed. Thaum lub qhov muag tau txais qhov kab noj hniav tshaj qhov kho qhov muag, lub kaw lus nce rau ntawm lub laser pib thiab emits laser teeb. Cov tshuaj tau raug siv tau siv raws li tau txais cov xov xwm thiab cov kab noj hniav hauv txoj kev kawm. Lawv nquag pom hauv cov zaub mov thiab tshuaj thiab siv rau hauv cov khoom muaj peev xwm thiab cov ntaub ntawv tsim nyog. Cov tshuaj siv tsis siv tshuaj chillically hloov kho nyob rau hauv txhua txoj kev, yog li kev pom pom, saj thiab khoom noj khoom haus uas tsis tau hloov pauv, thiab nws tus nqi ib puag ncig tswj tau.
Pab pawg tshawb fawb systematically pom zoo cov zaub mov ntxiv ntxiv thiab thaum kawg txheeb xyuas ob peb tus key Laser Txais Khoom:
- Chlorophyl tsev neeg: Txoj kev tshawb pom pom tias Quantum tawm los ntawm chlorophyll-a hauv sunorophyl-a nyob rau hauv sunflower roj mus txog {1, uas yog txaus los txhawb nqa laser emission. Cov tshuaj chlorophyll confectural muaj nyob rau hauv cov txiv roj roj tuaj yeem ua tiav cov txiaj ntsig laser yam tsis muaj tshuaj ntxiv.
- Vitamin B2 (Riboflavin): Nrog Quantum tawm ntawm 0. 27, nws ua tau zoo nyob rau hauv cov kua aqueous thiab muab cov khoom siv roj zoo tshaj plaws rau cov khoom siv dej.
- Neeg ua tsuam: Cov khoom noj khoom haus ib txwm muaj ua tau zoo laser kev ua haujlwm zoo laser hauv ib puag ncig roj, nthuav nws cov ntawv thov ntau.
Kev Ua Kom Qav Cavity Architecture Tsim
Qhov kev xaiv ntawm cov ntaub ntawv uas muaj resonant kab noj hniav yog nyob ntawm kev teeb tsa thiab ua haujlwm ntawm microcer. Feem ntau cov ntaub ntawv no yuav tsum tau pob tshab, thiab hauv qee qhov kev teeb tsa, butter, chitosan thiab nyias cov nyiaj rov qab tuaj yeem siv los ua cov kab noj hniav. Nyob rau hauv cov nqe lus ntawm Laser Cegerity Tsim, cov kws tshawb fawb nrhiav pom tau ob lub vajtse tshiab:
Whispering Gallery hom (WGM): Siv Optical tag nrho kev cuam tshuam nrog cov roj mob lossis cov khoom siv tau, wgms feem ntau muaj Q yam ntxwv. Cov kev tshawb fawb pab ua tiav kev siv lasing siv 2 hli chlorophyll-a lossis 4 hli carmine yaj nyob rau hauv cov roj sunflower. Rau chlorophyll-doped tee, ntsuas q tshaj plaws tshaj 9 {} 00 00 00 00 00 00, nrog ib nrab lasing pib ntawm 4.5 μEJ. Qhov tsawg kawg nkaus yog qhov loj me uas yuav tsum tau ua kom tiav txoj kev nce qib yog li 35 μm. Ntxiv rau chlorophyll-a, tsis muaj-huv chlorophyll sib xyaw los ntawm cov roj txiv roj tuaj yeem muab tso tawm los ntawm cov roj txiv roj tuaj yeem tawm hauv dej, tab sis cov kev nce qib yog txog peb zaug siab dua. Txiv roj roj ib txwm muaj cov chlorophyll yog siv los ua laser hauv daim ntawv ntawm cov roj roj tsis tas li ntawm lwm yam tshuaj. WGM peaks tau pom nyob rau hauv lub spectrum hauv qab noting pib lub chaw siv kev zoo siab siv txoj phuam txuas ntxiv (CW) laser lossis lub teeb emitting diode (coj).
Fabry-pot (FP): Ib kab noj hniav sib txawv uas muaj ob tsom iav nrog qhov muaj qhov nruab nrab ntawm lawv. Cov lus thov laser siv edible nyiaj tawm ntawm cov iav rawv, thiab cov pa roj hmab ntawm cov iav sunflaved, thiab cov txiv ntoo sib tsoo los ntawm cov iav slougbavin sodium phosphlected nyob rau hauv aqueous daws. Thaum cov kab noj hniav tau sau nrog chlorophyll-doped sunflower roj tau tshwm sim nyob rau hauv FP qhov chaw nres tsheb, nrog ib qho kev sib luag ntawm cov 5.9 μÄ {6 μJ. Lasing kuj tseem ua tiav siv cov kab noj hniav uas muaj nrog riboflavin sodium phosphte kev daws teeb meem.
Unclonable precision barcode
Qhov kev kawm no qhia cov ntaub ntawv precision encoding ntawm cov microlasers siv tau. Cov mlom loj uas tau npaj los ntawm cov microfluidics muaj qhov loj sib txawv ntawm coeffiation ntawm tsuas}. 4%, uas tuaj yeem ua tiav nanoscale loj tswj qhov raug. Qhov loj me ntawm txhua qhov kev ntsuas tuaj yeem ntsuas los ntawm laser spectroscopy nrog kev ua yuam kev ntawm tsuas yog 1.2 n. Pab pawg tshawb fawb tau tsim 14- ntsis} ntsis binary coding system uas tuaj yeem tsim muaj 16,384 cim cov lej cim npe. Qhov no yog txaus kom encode cov ntaub ntawv tseem ceeb xws li cov khoom lag luam cov ntaub ntawv, hnub ntau dua, hnub tas sij hawm, thiab keeb kwm. Vim tias cov kev txwv ntawm lub cev ntawm cov txheej txheem npaj npaj, cov cim no yog lub cev tsis zoo, muab cov khoom tiv thaiv kev tiv thaiv tus nqi ntau.
Nyob rau hauv cov qauv qhia tseeb, pab neeg tshawb fawb tau tiav "Hnub Thoob Ntiaj Teb nres cov khoom noj khoom haus, Lub Plaub Hlis 26, 2}! Tag nrho cov txheej txheem coding tsuas yog muaj 5 μl ntawm sunflower roj, thiab lub zog txhawb nqa rau 500 ml ntawm cov khoom lag luam tsis zoo (tsuas yog 0.008 kcal \/ 100 ml). Tom qab ib xyoos ntawm kev cia, cov ntaub ntawv encoded tseem tuaj yeem nyeem tau zoo.
Kev Tshawb Fawb Ntau Tshaj Plaws rau Kev Nyab Xeeb Kev Nyab Xeeb
Ntxiv nrog rau kev tawm tsam kev ua haujlwm, cov txheej txheem tseem pom muaj peev xwm paub txog kev saib xyuas muaj zog, muab kev tswj xyuas kev nyab xeeb rau kev nyab xeeb noj:
Kho kom haum kev ntsuas ntawm cov suab thaj: Siv cov rhiab ntawm WGM kab noj kab noj kab noj hniav rau lub nruab nrab ntawm nruab nrab, cov qab zib}. 2% yog piv rau kev ua haujlwm ntawm cov lag luam refacttometers. Qhov no yog qhov tseem ceeb rau kev tswj hwm zoo xws li caw thiab kua txiv.
Kev saib xyuas cov nqi ntawm PHIC: Los ntawm cov ph-xov xwm nthuav dav ntawm Chitosan zaj duab xis, lub v kuaj tau nrog qhov tseeb ntawm {1}}. 05 phua ua tiav tau tiav. Nyob rau hauv cov mis lwj sim, kev hloov pauv ntawm PH tau ntau hnub tau ua tiav, muab cov cuab yeej tshiab rau kev twv xyuas lub neej mis nyuj.
Microbial Kev Tshawb Nrhiav Kev Loj Hlob: Kev siv cov khoom noj muaj txiaj ntsig tshiab ua rau cov kab mob nruab nrab, thaum lub teeb liab laser poob lawm, ntxias tau tias qhia meej microbial. Qhov no "tus kheej-kev puas tsuaj" Sensor cov ntsiab lus qhib txoj kev tshiab rau cov zaub mov lwj ntxov.
Qhov Ntsuas Kub Raug Taus: Cov rog roj uas siv tau nrog cov ntsiab lus melting sib txawv yog siv los ua kom ntsuas kub-rhiab-rhiab. Thaum raug rau qhov kub tshaj qhov ntsuas kub thiab txias saum toj no, tus qauv hloov pauv tas li, muab cov txheej txheem kaw tsis tu ncua rau kev xa khoom txias saib xyuas.
Cov ntsiab lus thiab Outlook
Qhov kev kawm no qhia tau ntau ntau cov lasers thiab lawv cov kev siv hauv kev ua kom muaj kev nyab xeeb zaub mov thiab tshuaj. Nws yog thawj qhov kev kawm ua haujlwm ntawm cov khoom siv laser ua kom zoo thiab cov microcavorities, qhia qhov kev ua tau zoo ntawm cov micolasers zoo li cov sensors thiab barcodes. Cov pab pawg tshawb fawb tau taw qhia tias ntxiv rau cov zaub mov, cov thev naus laus zis kuj tseem tuaj yeem siv rau kev saib xyuas zoo thiab kev saib xyuas ib puag ncig xws li cov tshuaj pleev ib ce thiab cov khoom siv tshuaj pleev ib tog. Nyob rau tib lub sijhawm, cov tswvyim no tuaj yeem txuas ntxiv mus rau biomedical teb xws li tshuaj ntsiav thiab kev cog tshuaj mob thiab cov cuab yeej siv rau cov tshuaj tshiab rau tus kheej.
Lub peev xwm loj ntawm cov roj Laser hauv kev nyab xeeb zaub mov muaj kev daws teeb meem kev nyab xeeb rau kev nyab xeeb hauv ntiaj teb. Raws li thev naus laus zis paub ntxiv, lub sijhawm tshiab ntawm "cov khoom noj ntse" yuav muaj nws tus kheej daim npav saib xyuas kev noj qab haus huv.
