“…I It was more than (95 %) after (72 hours), when the irradiation power was (400mJ) at 20sec of irradiation time., as shown in Figure 9. The obtained results are similar to those of previous studies [1,3]. It is clear that laser has a real and fast effect, especially at high energies and long exposure time.…”

“…The respiratory chain of mitochondria in a biological cell is affected by laser, also it changes the electrical potential of cell membranes affects their selective transmittance to some ions, or the activity of some enzymes may increase. It may also double the DNA and lead to collagen production, cell proliferation or alteration of their motor properties [3]. The characteristics of the tissues as well as the properties of laser source are the two factors that depend on how laser affects the tissues themselves [16].…”

The subject of biophysics is interdisciplinary and covers various fields of biology and physics. In this research the effect of some parameters of Nd:YAG laser on ants (Camponotus consobrinus) has been studied . This includes the effect on its external shape, as well as the percentage of the killing rate obtained. A laser radiation of a wavelength (1.064 µm) with different energies: (300, 320, 340, 360, 380 and 480 mJ) was used to irradiate ants placed at a distance of (10 cm) distance from the laser source . The irradiation times were (15 and 20 sec) for each energy. The obtained results showed an increase in the rate of ant mortality, as well as an increase in deformations, as the laser energy and the irradiation time increased. These results were recorded after different time periods (12, 24, 48 and 72 hours) after laser treatment.. The thermal diffusion within the tissues resulting from laser radiation causes increased death rates due to damage of internal structures.
