The investigation of chitin influence in laser induced deformation of butterfly wings

The investigation of laser beam irradiation on different types of butterfly wings has been done previously by using the holographic method. The deformations due to the use of different laser wavelengths were observed. It is well-known that chitin is an abundant component of many complex structures in biological samples, such as butterfly wings. Consequently, as the influence of the chemical structure was taken into account, it was decided to examine the influence of chitin itself in laser-induced deformation in biological samples. Therefore, in this work, the same tests were performed on the film generated from chitin by using different wavelengths of laser. The results obtained strongly suggest that there are no effects of laser beam irradiation on chitin, indicating that chitin itself does not have an influence on the observed deformation of the butterfly wings. It was decided to make some additional measurements of such wings, which would be important for the further course of research in this direction. Some useful graphs were obtained by X-ray diffraction (XRD) and Fourier-Transform Infrared Spectroscopy (FTIR) measurements of particular butterfly wings. The obtained results contribute to a better knowledge of the structure and morphology and may have applications in the industry of artificial materials, especially polymers.
