Exact action spectra for cellular responses relevant to phototherapy.
TLDR
In the wavelength range important for phototherapy (600-860 nm), there are four "active" regions, but peak positions are not exactly the same for all spectra, so exact parameters of peak positions and bandwidths are presented. Expand
Absorption measurements of a cell monolayer relevant to phototherapy: reduction of cytochrome c oxidase under near IR radiation.
TLDR
The absorption measurements have revealed that the 710- to 790-nm spectral region is characteristic of a relatively reduced photoacceptor, while the 650- to 680-nm one characterizes a relatively oxidized photo acceptor, and the ratio between the peak intensities at 760 and 665 nm is used to characterize the redox status of cytochrome c oxidase.

Absorption measurements of cell monolayers relevant to mechanisms of laser phototherapy: reduction or oxidation of cytochrome c oxidase under laser radiation at 632.8 nm.
TLDR
The experimental results of this work demonstrate that irradiation at 632.8 nm causes either a (transient) relative reduction of the photoacceptor, putatively cytochrome c oxidase, or its (transients) relative oxidation, depending on the initial redox status of thephotoacceptor. Expand
Changes in absorbance of monolayer of living cells induced by laser radiation at 633, 670, and 820 nm
