The present study placed to fabricate nanofibers finded on β-cyclodextrin grafted chitosan (β-CD-g-CS) macromolecules with incorporated drug via the blend electrospinning technique. The grafting of β-CD onto chitosan (CS) was corroborated by FT-IR, (1)H NMR, TGA, XRD, and EDX analysis. Snag it now was capsulized in the β-CD-g-CS matrix as blend nanofibers utilizing electrospinning in presence of polyvinyl alcohol (PVA).
The SEM epitomes disclosed nanofibers with diameters at the nanoscale. The unique features of β-CD-g-CS/PVA as drug delivery system were investigated using indomethacin as a model drug molecule. operated release of indomethacin from nanofibers was canvased in PBS solution by measuring the absorbance by UV-Vis spectrophotometer. The drug release profile exhibited that the rate of drug release can be cuted by polymer type and deepening the drug/polymer ratio. The physicomechanical dimensions of the originated nanofibers were analyzed by tensile strength and water contact angle. The results established that β-CD-g-CS unveiled enhanced wettability as well as favorable physicomechanical holdings. In addition, the growth rate of the L929 cadres on the CS and β-CD-g-CS nanofibers was not significantly suppressed and even meliorated cell proliferation.
These determinations indicated that β-CD-g-CS nanofibers could be appropriate as a smart drug delivery system for sustained release of indomethacin as an anti-inflammatory medicine in the wound healing and tissue engineering comings in orthopedic diligences.Post ingrafted gallic acid to chitosan-Ag hybrid nanoparticles via free radical-induced grafting responses.The present study purposes two unique arrangements habituating free radical-inducted grafting reactions to combine Ag, chitosan (CS) and gallic acid (GA) into a single particulate nanostructure. GA-ingrafted-CS (GA-g-CS) was used to reduce Ag(+) to Ag(0), and producing Ag-GA-g-CSNPs (hybrid NPs I) GA was engrafted into CS-AgNPs, to form GA-g-CS AgNPs (hybrid NPs II). Although there were previous endeavours to graft GA into CS, this is first time to graft GA into CS-AgNPs. The study proposed to enhance biocompatibility, antibacterial and antioxidant places of CS-AgNPs via grafted GA. Grafting GA into CS-AgNPs was confirmed by UV-Vis, DLS, DSC/TGA, XRD, EDX and FTIR.
The morphology and size of NPs were canvased by TEM and SEM. The decrease of ζ-potential from +50 mV in CS-Ag NPs to +33 and + 29 mV, in the presented 2 nanoforms hybrid NPs I and II, respectively, is an indication for the successful GA graft. Among all samples, hybrid NPs II showed lower toxicity, higher antioxidant and antibacterial activity. The finded issues exposed that ingrafting GA to CS-AgNPs, as a new method to combine Ag, CS and GA in a uniparticulate structure, is a unique process which may deserve a more future consideration.Comparative Study of Sonophotocatalytic, Photocatalytic, and Catalytic Activities of Magnesium and Chitosan-Doped Tin Oxide Quantum Dots.The present study marchs the hydrothermal synthesis of SnO(2) quantum dots (QDs) doped with different concentrations (2, 4 wt %) of magnesium (Mg) and a desexualized amount of chitosan (CS). Selenoproteins prevailed samples were investigated through a number of characterizations for optical analysis, elemental composition, crystal structure, functional group presence, interlayer spacing, and surface morphology.
The XRD spectrum revealed the tetragonal structure of SnO(2) with no significant mutants happening upon the addition of CS and Mg. The crystallite size of QDs was contracted by incorporation of dopants.
