“…The gel is a nonlocal medium with strong coupling between neighboring regions. Consequently, stable modes of acoustic oscillations appear in the gel vessel, influenced by both the elastic properties of the gel and the characteristics of the vessel [39]. If the characteristic periods T (inverse frequencies) of such modes are significantly larger than the characteristic recession times of the correlation function ( 5) or (6), they manifest as small cosine oscillations at the tail of the correlation function (refer to, for instance, Figure 5 in [40]).…”

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.
