Puas muaj cov tshuaj pleev ib ce uas tuaj yeem kho qhov kev puas tsuaj los ntawm kev raug tshav ntuj lossis ib puag ncig co toxins ntawm koj daim tawv nqaij? Raws li kev tshawb fawb luam tawm rau lub Kaum Ib Hlis 2nd hauv phau ntawv journal "Regenerative Medicine" ntawm Nature, cov kws tshawb fawb ntawm Northwestern University hauv Tebchaws Meskas tau tsis ntev los no tau tsim cov khoom siv biomimetic melanin uas tuaj yeem ua raws li ntuj tsim melanin hauv tib neeg cov tawv nqaij thiab tuaj yeem siv hauv zos rau cov tawv nqaij raug mob. ua kom lub qhov txhab zoo.
Cov dawb radicals yog tsim los ntawm cov tawv nqaij puas xws li tshav kub kub, kev laus, kev ua qias tuaj ib puag ncig, thiab lwm yam. Yog tias tsis tswj tau, kev ua haujlwm dawb radical tuaj yeem ua rau cov hlwb puas, thaum kawg ua rau cov tawv nqaij laus thiab mob qog noj ntshav. Lub hauv paus ntsiab lus ua haujlwm ntawm cov khoom tsim biomimetic melanin yog tshem tawm cov dawb radicals.
Cov hluavtaws melanin engineering nanoparticles tsim los ntawm cov kws tshawb fawb tau hloov kho cov qauv ntawm melanin. Piv rau tib neeg melanin, txhua gram ntawm hluavtaws melanin tuaj yeem tshem tawm ntau cov dawb radicals, ib yam li "super melanin". Nws yog biocompatible, biodegradable, non-toxic, thiab pob tshab thaum siv rau ntawm daim tawv nqaij. Tom qab siv rau ntawm daim tawv nqaij, melanin yuav nyob twj ywm rau ntawm daim tawv nqaij thiab tsis tau absorbed rau hauv cov khaubncaws sab nraud povtseg, yog li tiv thaiv daim tawv nqaij los ntawm tshav ntuj thiab kho cov tawv nqaij uas tau sunburned los yog chemically hlawv.
Cov kws tshawb fawb tau sim cov txiaj ntsig ntawm hluavtaws melanin ua cov tshuaj pleev thaiv hnub. Nws tau pom tias nws tuaj yeem tshem tawm cov dawb radicals, tiv thaiv daim tawv nqaij, thiab tseem tuaj yeem siv hauv zos tom qab raug mob ntawm daim tawv nqaij los txhawb kev kho ntawm daim tawv nqaij. Tsis tas li ntawd, cov tshuaj no kuj siv tau los kho cov pob khaus thiab qhib qhov txhab.
Qhov kev sim zaum kawg no qhia tau hais tias hluavtaws melanin tsis ua rau tib neeg tawv nqaij thiab tuaj yeem tiv thaiv cov ntaub so ntswg los ntawm cov teebmeem ntawm hluav taws xob hluav taws xob. Qhov no yuav dhau los ua ib txoj hauv kev zoo rau kev kho cov tawv nqaij kub hnyiab los ntawm kev raug hluav taws xob, nrog rau kev xaiv rau cov neeg mob qog noj ntshav tau txais kev kho hluav taws xob.
