3D Printing of Biocompatible and Antibacterial Silica-Silk-Chitosan-Based Hybrid Aerogel Scaffolds laded with Propolis.The aim of this study is to design a therapeutic heightened three-dimensional (3D) silk fibroin (SF)-based scaffold holding propolis (Ps)-loaded chitosan (CH) nanocarriers. To  use of vitamin d3 , we initially synthesised a hybrid gel-based ink by a synergistic sol-gel and self-assembly approach and then processed the leaving gels by microextrusion-based 3D printing traced by supercritical drying to obtain 3D hybrid aerogel scaffolds. Ps was applyed to enhance the final scaffold's bactericidal efficacy and cell responsiveness. For the synthesis of the scaffold, two Ps loading methods (in preprint and postprinting stairs) were inquired in order to optimize the Ps drug amounts in the scaffold and maximize the antibacterial holdings of scaffold. In the postprinting Ps loading step, the hybrid silica-oxidated SF (SFO)-CH hydrogel ink was 3D printed into a construct with an interlinked porous structure, and then, Ps was charged into the impressed construct.

In the preprint loading method, PS was comprised into the SF and a hydrolysed silane solution prior to gelation. The morphological reports demonstrate that the addition of Ps capsulized CH nanoparticles (NPs) into the hydrogel solution amended the porosity of the prepared scaffolds. The rheological analysis of the contrived gel ink with and without Ps loading and the release kinetics were considered. The antimicrobial solvents show that the Ps-adulterated scaffolds in the postprinting step presented superior antibacterial activity against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) strains likened to a preprinted Ps-adulterated scaffold. Direct and indirect in vitro cytotoxicity exams also substantiated the contrived Ps-loaded scaffold biocompatibility toward a mouse fibroblast (L929) cell line.

We exhibited that the scaffold phrased by propolis-loaded chitosan NPs can enhance the migration and proliferation of L929 fibroblast cubicles. The obtained resolutions prove the promise of the contrived 3D printed silica-SFO-CH-Ps scaffolds as a potent 3D scaffold to mediate tissue regeneration but also as an antibacterial highly porous matrix to support wound healing.Synthesis and characterization of methacryl glycol chitosan as a novel functionally advanced thermogel for biomedical diligences.Thermo-responsive hydrogels (thermogels), cognized for their sol-gel transition capabilities, have collected significant interest for biomedical applications over recent tenners conventional thermogels are impeded by intrinsic physicochemical and functional limits that impede their broader utility. This study introduces methacryl glycol chitosan (MGC) as a novel thermogel, offering enhanced functionality and addressing these limitations synthesized through N-methacrylation of glycol chitosan, exhibit tunable thermogelling and photo-crosslinking doingsses. The thermo-reversible sol-gel transition of MGCs occurs within a 21-54 °C range, adjustable by polymer concentration and methacryl substitution degree. Photo-crosslinking employing UV light further heightens the mechanical properties of MGC thermogels, making thermo-irreversible, chemically crosslinked hydrogels.
