No Studies Identified for 1,072 nm Wavelength in Wound Healing or Cellular Metabolism
The available evidence does not include any research examining the specific wavelength of 1,072 nm for effects on cellular metabolism or wound healing at varying irradiances.
Evidence for Related Near-Infrared Wavelengths
The closest available data examines wavelengths in the near-infrared spectrum, but none approach 1,072 nm:
Effective Wavelengths Documented in Research
810 nm demonstrated the strongest wound healing effects in partial-thickness dermal abrasion models, with significant wound area reduction, enhanced collagen accumulation, complete re-epithelialization, and accelerated cellular proliferation compared to control groups 1
980 nm showed no stimulated healing in dermal abrasion models, despite being in the near-infrared range 1
980 nm required much lower fluence for initial cell stimulation but produced only short-term ATP elevation, whereas 660 nm caused more durable responses lasting at least 24 hours 2
Wavelength-Dependent Mechanisms
The biological response depends critically on the specific wavelength employed, with effectiveness explained by the absorption spectrum of cytochrome c oxidase, the candidate mitochondrial chromophore in photobiomodulation 1
Theoretical modeling suggests optimal wavelengths for therapeutic treatments are in the red region with a local maximum at 730 nm for tissue penetration depth 3
Different response pathways are involved at different wavelengths, with 660 nm and 980 nm triggering distinct cellular mechanisms 2
Critical Gap in Evidence
No published studies in the provided evidence base examine wavelengths beyond 980 nm for wound healing or cellular metabolism effects 4, 1, 3, 2
The 1,072 nm wavelength falls outside the documented therapeutic window where photobiomodulation effects have been systematically studied with varying irradiances 1, 3
Clinical Implications
Extrapolation from 980 nm data to 1,072 nm would be scientifically unfounded, as even the difference between 810 nm (effective) and 980 nm (ineffective) demonstrates dramatic changes in biological response 1
Wavelengths must match chromophore absorption spectra to produce therapeutic effects, and 1,072 nm may fall outside relevant absorption peaks for cytochrome c oxidase or other photoacceptors 1, 3
