دراسة تاثير نمط تشغيل ليزر النيديميوم-ياك على قتل Escherichia coli في محلول محلي

Samples of physiological solution containing the bacteria Escherichia coli in the size of 0.5 cm J where prepared to study the effect of Nd-YAG Laser Mode Working on Killing Escherichia coli in Saline Solution. Irradiation of the samples were carried out for different periods and the same amount of radiation dose and the wavelength to compare between high and low power laser to percent of bacterial killing. The results shows the high percent of killing by pulsing mode than continuous mode due to the crash of the cell by absorbing high-energy in a short time without sufficient time to expand the cell by heat.
