This article presents materials that highlight the bioengineering potential of polymeric systems of natural origin based on biodegradable polysaccharides, with applications in creating modern products for localized wound healing. Exploring the unique biological and physicochemical properties of polysaccharides offers a promising avenue for the atraumatic, controlled restoration of damaged tissues in extensive wounds. The study focused on alginate, pectin, and a hydrogel composed of their mixture in a 1:1 ratio. Atomic force microscopy data revealed that the two-component gel exhibits greater cohesion and is characterized by the presence of filament-like elements. The dynamic light scattering method indicated that this structural change results in a reduction in the damping of acoustic modes in the gel mixture compared to the component gels. Raman spectroscopy research on these gels revealed the emergence of new bonds between the components’ molecules, contributing to the observed effects. The biocompatibility of the gels was evaluated using dental pulp stem cells, demonstrating that all the gels exhibit biocompatibility.

In this work, the dynamic behavior of polyvinylpyrrolidone (PVP) hydrogel (2%) over time from the moment of dilution was studied using the dynamic light scattering (DLS) method. The stability of the dynamic characteristics, the persistent presence of a power-law component in the autocorrelation function (ACF) of scattered light intensity, and the appearance of artifactual relaxation times when using an exponential expansion program for the ACF were demonstrated. The fractal dimension of the PVP gel was determined to be D _f = 1.81.

We have detected the emergence of luminescence in pectin hydrogel, the disappearance or weakening of some lines present in the spectra of dry samples in th
