Kalafo ea laser ke kalafo ea bongaka e sebelisang leseli le shebaneng ho hlasimolla ts'ebetso e bitsoang photobiomodulation (PBM e bolela photobiomodulation). Nakong ea PBM, li-photon li kena ka har'a lisele 'me li sebelisana le cytochrome c complex ka har'a mitochondria. Tšebelisano ena e baka letoto la liketsahalo tse lebisang keketsehong ea metabolism ea sele, e ka fokotsang bohloko hammoho le ho potlakisa ts'ebetso ea pholiso.
Kalafo ea Photobiomodulation e hlalosoa e le mofuta oa phekolo ea leseli e sebelisang mehloli ea leseli e sa ioning, ho kenyeletsoa le li-laser, li-diode tse ntšang leseli, le/kapa leseli la broadband, ho spectrum ea electromagnetic e bonahalang (400 - 700 nm) le haufi le infrared (700 - 1100 nm). Ke ts'ebetso e seng ea mocheso e kenyeletsang li-chromophores tsa tlhaho tse hlahisang liketsahalo tsa photophysical (ke hore, linear le nonlinear) le photochemical maemong a fapaneng a baeloji. Ts'ebetso ena e fella ka liphetho tse molemo tsa kalafo ho kenyeletsoa empa ha li felle feela ho pholisong ea bohloko, ho fetola sesole sa 'mele, le ho khothaletsa pholiso ea maqeba le tsosoloso ea lisele. Lentsoe phekolo ea photobiomodulation (PBM) joale le sebelisoa ke bafuputsi le litsebi ho e-na le mantsoe a kang kalafo ea laser ea boemo bo tlase (LLLT), laser e batang, kapa kalafo ea laser.
Melao-motheo ea motheo e tšehetsang phekolo ea photobiomodulation (PBM), joalo ka ha e utloisisoa hona joale libukeng tsa mahlale, e batla e otlolohile. Ho na le tumellano ea hore tšebeliso ea tekanyo ea phekolo ea leseli ho lisele tse sa sebetseng hantle kapa tse sa sebetseng hantle e lebisa karabelong ea sele e tsamaisoang ke mekhoa ea mitochondrial. Lithuto li bontšitse hore liphetoho tsena li ka ama bohloko le ho ruruha, hammoho le tokiso ea lisele.
