Thymol-diluted chitosan-based nanogels (TLCBS) proved meliorated antimicrobial properties, especially against multidrug-resistant bacterial antagonists. creations such as bipolymer nanocarriers and thymol infused with photosensitive chitosan micelles offer advanced bactericidal strategies and show potential for bone tissue regeneration and wound healing. The incorporation of thymol also improved drug delivery efficiency and biomechanical strength, especially when united with poly(dimethylsiloxane) in chitosan-gelatin films. Thymol-chitosan compoundings have also readed promising diligences in oral delivery and periodontal treatment. This review highlights the synergy between thymol and chitosan in these productions, which greatly raises their therapeutic efficacy and foregrounds the novel use of essential oil factors. It also foregrounds the novelty of the reports guided, as well as their limitations and possible directions for the development of desegregated substances of plant and animal origin in modern and advanced medical coverings.
Antibacterial Activity Assessment of Chitosan/Alginate Lavender Essential Oil Membranes for Biomedical Applications.The demand for natural productions in the treatment of dermatological pathologies has advanced the use of bioactive substances such as lavender essential oil (LEO), which stands out for its anti-inflammatory and antioxidant holdings and its antimicrobial potential. Biopolymers such as chitosan (CHT) and alginate (ALG) are biodegradable and biocompatible and have demonstrated their viability in biomedical diligences such as skin regeneration. The inhibitory effect of LEO on the growth of skin-interrelated bacterial species Staphylococcus aureus, Staphylococcus epidermidis, Pseudomonas aeruginosa and the fungus Candida albicans was studied by incorporating 1% v/v LEO capsuled in CHT, ALG, and CHT/ALG membranes. Despite the verification of the antimicrobial effect of all type of membranes, no synergistic effect was mentioned following the addition of LEO. S. aureus and P.
aeruginosa presented the most growth on the different substratums and C. albicans established the highest inhibition. This is a first approach utilising microorganisms isolated from clinical samples or skin microbiota. Further investigation would be advisable practicing more clinical melodys for each microorganism to validate their biomedical applicability.Highly efficient and reusable CuAu nanoparticles supported on crosslinked chitosan hydrogels as a plasmonic catalyst for nitroarene reduction.The synthesis of CuAu-free-based monometallic (MNPs) and bimetallic nanoparticles (BNPs) confirmed on chitosan-established hydrogels for their application as catalysts is presented. The hydrogels lied of chitosan strings cross-linked with tripolyphosphate (TPP) in the form of beadings with an approximate average diameter of 1 mm.
The MNPs and BNPs were received by the adsorption of metallic ions and their subsequent reduction with hydrazine, achieving a metallic loading of 0 mmol per gram of dry sample, with average nanoparticle sizes that were found between 2 and 4 nm. Both procedures, metal adsorption and the stabilization of the nanoparticles, are mainly ascribed to the participation of chitosan hydroxyl, amine and amide functional groups. The materials revealed important absorption isthmusses in the visible region of the light spectra, specifically between 520 and 590 nm, mainly attributed to LSPR afforded the nature of the MNPs and BNPs inside the hydrogels the hydrogels were valuated as catalysts against the reduction of 4-nitrophenol (4NP) into 4-aminophenol (4AP), accompanyed by UV-visible spectroscopy. The kinetic advance of the reaction revealed important meliorations in the catalytic activity of the fabrics by synergistic effect of BNPs and plasmonic enhancement under visible light irradiation, given the combination of metals and the light harvesting attributes of the nanocomposites the catalytic performance of hydrogels stoping BNPs CuAu 3:1 showed an important selectivity, recyclability and reusability performance, due to the relevant interaction of the BNPs with the chitosan matrix, highlighting the potential of this nanocomposite as an effective catalyst, with a potential environmental application.
