According to the absorption spectra of blood and hemoglobin, a photon-bond energy formula is established using physical methods and the effects on hemoglobin of low-level laser at different wavelengths are analyzed. The results show that lasers with the peak wavelengths of 200∼240, 275, and 342 nm in the whole blood absorption spectra curve are easy to destroy protein molecules and then lead to hemoglobin lose biological activity. While lasers with wavelengths longer than 800 nm will reduce the oxygen carrying capacity of blood, only lasers with wavelengths between 630 and 670 nm have the best efficacy.
根据血液和血红蛋白的吸收光谱,采用物理方法建立了光子键能公式,并分析了不同波长的低强度激光对血红蛋白的影响。结果表明,全血吸收光谱曲线中峰值波长为200~240、275和342nm的激光容易破坏蛋白质分子,进而导致血红蛋白丧失生物活性。而波长大于800nm的激光会降低血液的携氧能力,只有波长在630~670nm之间的激光疗效最佳。
