The 1070 nm wavelength used in photobiomodulation (PBM), including applications developed by Neuronic for brain health and function, is chosen based on scientific research and practical considerations related to tissue penetration and biological response.
Deep tissue penetration
Near-infrared (NIR) light in the range of 800–1100 nm is known for its ability to penetrate deeper into biological tissue compared to visible light or shorter infrared wavelengths. The 1070 nm wavelength falls within this NIR window, allowing light to reach deeper brain structures, which is especially important for applications involving the brain and central nervous system.
Interaction with mitochondrial function
A primary mechanism of PBM involves the absorption of NIR light by cytochrome c oxidase (CCO), a key enzyme in the mitochondrial electron transport chain responsible for cellular energy (ATP) production.
While commonly cited absorption peaks for CCO include wavelengths around 810 nm, 830 nm, and 904 nm, research indicates that wavelengths across the broader NIR spectrum can produce beneficial biological effects. The effectiveness of a specific wavelength—such as 1070 nm—depends on factors including target tissue depth and intended application.
