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

Abstract

Abstract.A craquelure structure of protein film as indicator of macromolecule state is discussing. Craquelure is a network of fine cracks or crackles on the surface of a painting, caused chiefly by shrinkage of paint film or varnish. The actions of laser radiation in the red and green spectral region on the protein film craquelure structure by the example of albumin are considering. It is experimentally shown that after drying the protein layer a craquelure pattern (variety of cracks in the layer) is formed with the parameters strongly modified by the laser action and depending on the wavelength of radiation and the time (energy density) of exposure.

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.…”

On the mechanism of the gallstone nucleus formation and the impact of laser radiation on its growth

“…The effect of laser radiation on protein solutions was studied in Ref. [9]. It was shown that as a result of the exposure of protein solution to laser radiation the craquelure structure (rupture pattern) of its dried film is changed.…”
