Paper Abstract

The aim of these experiments was a direct measurement of changes in absorption of cellular monolayers under diode laser irradiation. First, a sensitive method for multichannel registration of absorption of a cell monolayer in range 500 - 860 nm was developed. Second, absorption spectra of intact HeLa cells and those after irradiation the monolayer with light at 670 and 820 nm were recorded. Third, the comparison of the absorption spectra and action spectra (five dependences of DNA and RNA synthesis rate and adhesive properties of HeLa cell membrane on wavelength) was performed.
