Edible mealworms can be farmed to produce high-quality foods and proteins, useful as elements in human and animal nutrients. During this process biological waste is produced. This work researchs the usage of the biological waste as source to produce chitin and chitosan with different potential diligences. Different waste fractions were served, and the feasibility of chitin isolation was measured. Chitosan was descended, and pictures were invented and tested for meaned uses. Data indicate that biopolymers with different holdings can be holded from multiple biological waste fractions.

All samplings show antibacterial activity, while chitosan celluloids derived from molt show interesting dimensions for packaging uses. celluloids also trigger the expression of anti-inflammatory phenotype markers in macrophage cubicles, which may be useful for tissue engineering implantation uses biological waste from insect farming can be used to extract chitin and chitosan with different holdings, and therefore, suitable for different diligences.Self-pieced chitosan/gelatin nanofibrous conglomerations comprised thermosensitive nanocomposite bioink for bone tissue engineering.Chitosan-free-based thermosensitive bioink can be a potential option as bioinks for bone tissue engineering because of their excellent biocompatibility and crosslinker-free gelation at physiological temperature their low mechanical strength, poor printability, and low post-printing cell viability are some of their limitations. In this work, self-meeted nanofibrous conglomerations of chitosan and gelatin were readyed and comprised in chitosan-grinded bioinks to enhance printability, mechanical attributes, post-printing cell viability, and proliferation the optimal concentration of nanohydroxyapatite was checked, and the potential of the nanocomposite bioink was measured. Physiochemical, mechanical, and in vitro depictions were carried out for the developed nanocomposite bioink. The bioink had optimum printability at 10 % nanohydroxyapatite and cell viability >88 %.

The composite bioink had a low water uptake capacity (2 %) and disgraced within 3 weeks in the presence of lysozyme. Mechanical characterization unveiled an elastic modulus of about 15 kPa. Rheological analysis argued a higher storage modulus of the bioink samplings at 37 °C. ALP activity of 36 units/ml after 14 days of scaffold culture in osteogenic sensitives indicated high cellular activity. These outcomes advised that the incorporation of osteogenic nanohydroxyapatite and nanofibrous aggregates amended the overall osteogenic and physiochemical potential of the thermosensitive bioink.Crosslinked hydrogel diluted with chitosan-supported iron oxide and silver nanoparticles as burn wound dressing.burnings can result in infection, disability, psychosocial and economic issuings.

Advanced wound dressings like hydrogel absorb exudate and maintain moisture. Considering the antimicrobial places of silver nanoparticles and iron oxide nanoparticles, the efficiency of cross-joined hydrogel laded with chitosan-supported iron oxide and silver nanoparticles for burn lesions repair was enquired in animal model. Cellulose hydrogel dressing made from carboxymethylcellulose and hydroxyethylcellulose crosslinked with different absorptions of citric acid (10, 15, 20, and 30%) was acquired. The physicochemical features of the synthetized hydrogels admiting Fourier-Transform Infrared spectroscopy, Thermal behavior, welling properties, and Scanning Electron Microscope (SEM) were valued. The silver nanoparticles and iron nanoparticles were produced and the characteristics, cytotoxicity, antimicrobial activities and their synergistic effect were inquired. After suming nanoparticles to hydrogels, the impressions of the prepared wound dressings were investigated in a 14-day animal model of burn wound. The resultants evidenced that the mixture constituting 12 ppm AgNps, and IONPs at a concentration ≤100 ppm was non-cytotoxic the conceptualizations with 20% CA had a tumefying ratio of almost 250, 340, and 500 g/g at pHs of 5, 6, and 7 after one hour, which are lower than those of preparations with 5 and 10% CA.
