Khadi lanu lazachipatala: njira yopezera katemera wokhala ndi ma tattoo a quantum dot yaperekedwa

Zaka zingapo zapitazo, asayansi ochokera ku Massachusetts Institute of Technology adakhudzidwa ndi zovuta za katemera m'maiko obwerera m'mbuyo komanso omwe akutukuka kumene. M’malo otero, nthaŵi zambiri mulibe njira yolembera anthu m’chipatala kapena mwachisawawa. Pakali pano, angapo katemera, makamaka ubwana, amafuna okhwima kutsatira nthawi ndi nthawi ya katemera makonzedwe. Momwe mungasungire komanso, chofunikira kwambiri, kuzindikira munthawi yake zomwe komanso nthawi yomwe katemera amafunikira pamunthu payekha? Makamaka ngati chamoyocho chinagwera mwangozi m'manja mwa munthu wina wa bungwe ngati Madokotala Opanda Malire.

Asayansi ochokera ku MIT otukuka ukadaulo wa katemera ndi kuyambitsa munthawi yomweyo zinthu zomwe zili ndi madontho ochulukirapo pansi pakhungu. Pazojambula mutha kuyika zambiri za nthawi ya katemera, za katemera wokha, komanso za mtanda womwe mankhwalawa adatengedwa. "Zolemba" zomwe zidapangidwa sizikuwoneka ndi maso, koma zimatha kuwerengedwa pogwiritsa ntchito foni yamakono yosinthidwa yokhala ndi kamera yopanda fyuluta ya infrared. Madontho opangidwa ndi mkuwa amakhala okondwa kudera lapafupi ndi infrared ndipo amatha kuwerengedwa kuchokera pansi pakhungu ngakhale patatha zaka zisanu atagwiritsidwa ntchito (kuyesedwa mu labotale pa zitsanzo za khungu la munthu).

Njira yogwiritsira ntchito ndondomeko ya chidziwitso ndi kupereka katemera nthawi imodzi ikuphatikizapo kugwiritsa ntchito katemera osati syringe. Katemera ndi utoto zimatsekeredwa mu zinthu zomwe zimagwirizana komanso zosungunuka pang'ono, kuphatikiza shuga ndi polyvinyl acetate (PVA). Izi zimagwiritsidwa ntchito popanga singano zazitali za 1,5 mm zomwe zimaboola pamwamba pakhungu kenako ndikusungunuka. Kuyika kwa singano kumanyamulanso chidziwitso, chifukwa amabaya utoto wokhala ndi madontho a nanometer-level quantum (pafupifupi 4 nm m'mimba mwake) pansi pakhungu motsatira dongosolo. Kuyesera kwa makoswe amoyo kwasonyeza kuti katemera ndi njira imeneyi amapereka zotsatira zofanana ndi katemera ndi syringe.

Pafupifupi anthu 1,5 miliyoni amamwalira chaka chilichonse chifukwa chosowa katemera kapena katemera. Ngati njira yatsopano ya katemera yokhala ndi mbiri yachipatala pakhungu la wodwalayo imakhala yotheka, zithandiza kupulumutsa miyoyo yambiri.
