Unyango lweLaser lunyango olusebenzisa ukukhanya okugxile ekuvuseleleni inkqubo ebizwa ngokuba yi-photobiomodulation (i-PBM ithetha i-photobiomodulation). Ngexesha le-PBM, ii-photons zingena kwizicubu kwaye zisebenzisane ne-cytochrome c complex ngaphakathi kwe-mitochondria. Olu nxibelelwano lubangela uthotho lweziganeko ezikhokelela ekwandeni kwe-metabolism yeseli, enokunciphisa iintlungu kunye nokukhawulezisa inkqubo yokuphiliswa.
Unyango lwe-Photobiomodulation luchazwa njengohlobo lonyango lokukhanya olusebenzisa imithombo yokukhanya engeyiyo ionizing, kuquka ii-laser, ii-diode ezikhupha ukukhanya, kunye/okanye ukukhanya kwe-broadband, kwi-spectrum ye-electromagnetic ebonakalayo (400 - 700 nm) kunye ne-infrared ekufutshane (700 - 1100 nm). Yinkqubo engeyiyo i-thermal equka ii-chromophores ze-endogenous ezibangela iziganeko ze-photophysical (oko kukuthi, ezithe ngqo nezingeyo-linear) kunye ne-photochemical kwiikali ezahlukeneyo zebhayoloji. Le nkqubo iphumela kwiziphumo zonyango eziluncedo kubandakanya kodwa kungaphelelanga apho ekunciphiseni iintlungu, i-immunomodulation, kunye nokukhuthaza ukuphiliswa kwamanxeba kunye nokuvuselelwa kwezicubu. Igama elithi photobiomodulation (PBM) therapy ngoku lisetyenziswa ngabaphandi kunye neengcali endaweni yamagama anjenge-low level laser therapy (LLLT), i-cold laser, okanye i-laser therapy.
Imigaqo esisiseko exhasa unyango lwe-photobiomodulation (PBM), njengoko iqondwa ngoku kwiincwadi zesayensi, ilula kakhulu. Kukho ukuvumelana ukuba ukusetyenziswa komthamo wokukhanya kwezonyango kwizicwili ezingasebenzi kakuhle okanye ezingasebenzi kakuhle kukhokelela kwimpendulo yeseli elawulwa ziindlela ze-mitochondrial. Izifundo zibonise ukuba olu tshintsho lunokuchaphazela iintlungu kunye nokudumba, kunye nokulungiswa kwezicubu.
