Poly(vinyl alcohol) and poly(vinyl pyrrolidone) were blended and films were obtained by casting method. Glutaraldehyde, hydrochloric acid and lactic acid were added to investigate their effect on mechanical properties, swelling and solubility of the blends with the aim to find a possible material candidate for medium or long term implants. Combination of all three additives (lactic acid, glutar...

A novel greener method to impregnate silver nanoparticles (AgNPs) into microcrystalline cellulose (MCC) by curry leaf (Murraya koenigii) extract is presented. The active reduction of silver ions by curry leaf extract was explored for the in situ impregnation AgNPs into MCC. Transmission electron microscopy (TEM) analysis of MCC coated with AgNPs showed the formation of silver particle sizes in ...

OBJECTIVE The aim of this study was to investigate bone repair after the implantation of vancomycin-loaded poly-L-lactic acid/poly-ethylene oxide microspheres compared with vancomycin-unloaded poly-L-lactic acid/poly-ethylene oxide microspheres. METHODS Poly-L-lactic acid/poly-ethylene oxide microspheres were implanted in rat tibiae and evaluated for periods of 2, 4, 8, and 12 days and 4, 8, ...

Damage to peripheral nerves often cannot be repaired by the juxtaposition of the severed nerve ends. Surgeons have typically used autologous nerve grafts, which have several drawbacks including the need for multiple surgical procedures and loss of function at the donor site. As an alternative, the use of nerve guidance channels to bridge the gap between severed nerve ends is being explored. In ...

Antimicrobial films of poly (lactic acid) (PLA)/D-limonene/zinc oxide (ZnO)-based bio-nanocomposites were prepared via melt compounding and subsequent thermocompression. D-limonene was incorporated at concentrations 10 or 20 wt%, ZnO pure nanoparticles those organically modified with oleic acid (O-ZnO), an average diameter 13.5 nm, included 3, 5, 8 wt%. The plasticizing effect D-Limonene corrob...

Through the microwave assisted fast synthesis method, Zinc Magnesium Oxide nanocomposite was prepared. Zinc Magnesium Oxide nanocomposite heated at 500oC was used for further structural, optical and antibacterial studies. The Debye Scherrer equation was used to calculate the average particle size of the nanocomposite. The optical characterization of the oxide nanocomposite was carried out by UV...

lysozyme, as a model protein, was precipitated through the formation of protein-zn complex to micronize for subsequent encapsulation within poly (lactic-co-glycolic acid) (plga) microspheres. various parameters, including ph, type and concentration of added salts and protein concentration, were modified to optimize the yield of protein complexation and precipitation. the resulting protein parti...

Robust homoleptic zinc catalysts offer new opportunities for recycling polyesters such as poly(lactic acid) and poly(ethylene terephthalate) to obtain platform molecules in a plastics circular economy approach.
