Investigation of laser induced inhibition and simulation in biological samples

Abstract

In this research, some experimental measurements have been carried out to study the biological effects in-duced by laser irradiation on bacterial samples prepared by different ways and at different conditions. Con-sidering the induced samples, the effect of laser irradiation has been investigated through analyzing some of the properties of the transmitted and scattered laser beam for determining the stimulation or inhibition ex-perienced by the investigated sample. In this study absorbance and scattering values have been measured as indicators of sample response to the irradiation laser beam. Absorbance and scattering have been investigated for different irradiation and sample parameters. Significant responses related to inhibition and stimulation effects of the investigated samples have been obtained. These results may significantly contribute in deter-mining the effective utilization of the laser beam as a therapeutic tool for accelerating the wounds and burns healing of diabetic patients whom their response to anti-biotic is not appropriate. The simultaneous irradia-tion of samples with the use of anti-biotic shows significantly positive effect and fast response.
