The laser radiation action on the biological objects

Diagnostics of liquid properties by the example of bioorganic solutions

“…The resulting data (images with contour boundaries, numerical characteristics) are written in a file and displayed on the screen. We also added the possibility of filtering small contours (in the final image they are shown in a different colour and are not taken into account in calculations) [11].…”

“…In this way a ray-shaped pattern of lamellas with epitaxial recrystallization on the ray part playing the role of the substrate for the exsiccant solution is formed. The reduction of the thickness of the lamella rays after the laser irradiation shows that in the irradiated solution the cluster size is considerably reduced, which leads to the size reduction of the nucleation centres in the course of the film drying [5,7,11]. An alternative method of structure monitoring is to use the speckle pattern of the studied liquid.…”

Laser modification of liquid nutrient medium and antibiotic solutions with the assessment by the bacteria growth dynamics

“…In Refs. [6][7][8][9][10] it is shown that in relation to the protein and bile solutions this statement finds its experimental confirmation.…”

Craquelure structure of protein film modification under the laser radiation of different spectral range action

“…It is found that the patterns that appear in this case correlate well with the patient's health [1,4]. It was also found that the method of film crystallograms is capable of detecting the result of the laser radiation action on a biological fluid [6][7][8][9], namely, the size reduction of the structure elements consisting of macromolecules is recorded (the phenomenon of laser-induced nanoclusterization).…”

“…Possible applications of this effect may be related both to the control of the forming patterns aimed at the facilitation of decoding the resulting craquelure patterns and to the determination of the energy doses when exposing, e.g., medication solutions with the aim to activate them (similar to the analgesic activation under the intravenous irradiation of blood [9], which, in turn, allows the reduction of the narcosis amount).…”
