The use of glycerolates of biogenic elements as biocompatible precursors in sol-gel synthesis is an innovative direction and opens up new scientific and practical prospects in chemistry and technology of producing practically important biomedical materials, including hemostatic, antimicrobial, and wound healing materials. Using biocompatible precursors, silicon, zinc, boron, and iron glycerolates, new bioactive nanocomposite hydrogels were obtained by the sol-gel method. The composition and structural features of the hydrogels were studied using a complex of modern analytical techniques, including TEM, XRD, AES, and ESI MS.

Objective: Using two biocompatible precursors, silicon and iron glycerolates, a new bioactive nanocomposite silicon‒iron glycerolates hydrogel was obtained by sol-gel method.
Methods: The composition and structural features of the hydrogel were studied using a complex of modern analytical techniques, including TEM, XRD, and AES.
Article Synopsis
- Recent research highlights the effectiveness of non-ablative Nd:YAG laser for treating skin conditions, thanks to its deep penetration, minimal side effects, and quick recovery for patients.
- The study explores how skin stressors can lead to oxidative damage, which affects aging and can cause diseases, emphasizing the importance of maintaining a balanced antioxidant defense system.
- Findings show that the Q-switched Nd:YAG laser enhances antioxidant defense and wound healing by influencing key molecular pathways, while also reducing collagen degradation.
Biocatalysts based on the methylotrophic yeast VKM Y-2559 immobilized in polymer-based nanocomposites for the treatment of methanol-containing wastewater were developed. The organosilica composites with different matrix-to-filler ratios derived from TEOS/MTES in the presence of PEG (SP-composite) and from silicon-polyethylene glycol (STP-composite) differ in the structure of the silicate phase and its distribution in the composite matrix. Methods of fluorescent and scanning microscopy first confirmed the formation of an organosilica shell around living yeast cells during sol-gel bio-STP-composite synthesis.
