Photosensitizers yog cov molecules uas nqus lub teeb (hν) thiab hloov lub zog los ntawm qhov teeb meem teeb mus rau lwm qhov chaw nyob ze. … Thaum absorbing photons ntawm hluav taws xob los ntawm qhov teeb meem teeb meem, photosensitizers muaj peev xwm los txhawb ib lub xeev hauv av electron mus rau hauv lub xeev singlet zoo siab.
Photosensitization ua li cas?
Photosensitization, txheej txheem ntawm kev pib cov tshuaj tiv thaiv los ntawm kev siv cov khoom muaj peev xwm nqus lub teeb thiab hloov lub zog mus rau qhov xav tau reactants.
Lub luag haujlwm ntawm Photosensitization hauv cov tshuaj niaj hnub yog dab tsi?
Photosensitization tso cai a nonabsorbing acceptor hom kom txaus siab nyob rau hauv lub xub ntiag ntawm lub teeb-absorbing pub molecule.
Dab tsi yog photosensitizers hauv kev kho mob photodynamic?
Photodynamic therapy (PDT) yog ua raws li siv lub teeb-sensitive molecules hu ua photosensitizers. Photoactivation ua rau tsim ntawm singlet oxygen, uas tsim cov tshuaj peroxidative uas tuaj yeem ua rau cell puas thiab tuag.
piv txwv zoo tshaj ntawm photosensitizer yog dab tsi?
Qhov tshwm sim ntawm cov khoom lag luam yog qee zaum photosensitizers lawv tus kheej. Tej zaum qhov piv txwv zoo tshaj plaws yog tsim kynurenine los ntawm tryptophan. Qhov no yog qhov tseem ceeb hauv kev kho mob cataract tsim, qhov twg crosslinking ntawm crystallines nyob rau hauv lub lens tau tshwm sim.
