Golflengten van roodlichttherapie: Hoe te kiezen 660 nm vs. 830 nm op basis van weefseldiepte
Wavelength determines whether photons reach their target tissue or get absorbed along the way. Rood licht (630–660 nm) penetrates 1–5 mm, making it ideal for skin, wonden, and hair follicles. Nabij-infrarood (810–850 nm) penetrates 10–50 mm, reaching muscle, gewrichten, and even transcranial targets. Both wavelengths activate cytochrome c oxidase (CcO) but at different absorption sites — the heme center […]
LED vs. Laser in Photobiomodulation: Performance, Veiligheid & Device Selection Guide
LEDs and lasers produce therapeutically equivalent outcomes in photobiomodulation when matched for wavelength, bestraling, and dose. The primary technical difference is coherence — lasers emit coherent (in-phase) light while LEDs emit incoherent light. Echter, peer-reviewed research demonstrates that coherence is not required for PBM’s biological effects (de Freitas & Hamblin, 2016; PMC5215795). LEDs offer significant […]
Downstream Biological Effects of Photobiomodulation: What Happens Inside Your Cells
Red light therapy works by delivering specific wavelengths of light — 630–660 nm (rood) and 810–850 nm (bijna-infrarood) — into the skin and underlying tissue, where the photons are absorbed by an enzyme called cytochrome c oxidase (CcO) inside the mitochondria. This absorption restores mitochondrial electron transport, increases ATP (Cellulaire energie) productie, releases nitric oxide […]
Bifasische dosisrespons bij PBM: Waarom meer licht niet altijd beter is
Biphasic dose response means that photobiomodulation (PBM) volgt een karakteristieke curve waarbij lage doses stimuleren, gematigde doses produceren optimale effecten, en hoge doses remmen de cellulaire functie. This phenomenon — described by the Arndt-Schulz principle and validated extensively in PBM research (Huang et al., 2009) — verklaart waarom meer licht niet altijd beter is. Echter, the specific optimal dose depends […]
Cytochroom c-oxidase: De primaire fotoacceptor bij roodlichttherapie
Cytochroom c-oxidase (CcO) – ook bekend als Complex IV van de mitochondriale elektronentransportketen – is de belangrijkste fotoacceptor bij rood- en nabij-infraroodlichttherapie. Wanneer fotonen in het bereik van 600–900 nm de mitochondriën bereiken, CcO absorbeert ze, drie belangrijke reacties uitlokken: verhoogde ATP (Cellulaire energie) productie, vrijkomen van stikstofmonoxide (een vaatverwijder die de bloedstroom verbetert), […]
What Is Photobiomodulation? Definitie, Geschiedenis & Hoe het werkt
Fotobiomodulatie (PBM) is a non-invasive therapy that uses specific wavelengths of red and near-infrared light (typically 600–1000 nm) to stimulate cellular energy production and promote tissue repair. Light photons are absorbed by an enzyme called cytochrome c oxidase in the mitochondria, boosting ATP synthesis and triggering anti-inflammatory, regenerative, and neuroprotective responses. You may know it by […]
