low density polyethylene films incorporating different types of organically modified nanoclays were prepared. physical, surface morphology and mechanical properties of the films were analyzed by x-ray diffraction pattern, scanning electron microscopy and tensile strength (ts) and length increase until fracture point (e) parameters, respectively. colony counting method was used to investigate an...

Biofunctional quadripartite films were developed by adding trans-Cinnamaldehyde (CIN) (0.4, 0.8, and 1.6% w/v) into chitosan (CH)/poly(vinyl alcohol) (PVA)/fish gelatin (FG) matrices. Rheological data revealed that all solutions exhibited shear-thinning typical entangle polymers behavior. Mechanical results showed the incorporation of CIN caused a significant increase (p < 0.05) in tensile stre...
a novel starch/poly (vinyl alcohol)/nano-titanium dioxide (st/pva/nano-tio2) biodegradable nanocomposite film was prepared by homogeneously dispersed tio2 nanoparticles in different ratios of starch/pva-based materials, via a solution casting method. glycerol was used as plasticizer. the mechanical and thermal properties of films were studied using tensile and perforation strength tests and the...
Bionanocomposite packaging materials have a bright future for a broad range of applications in the food and biomedical industries. Antimicrobial packaging is one of the bionanocomposite packaging materials. Silver nanoparticle (AgNP) is one of the most attractive antimicrobial agents for its broad spectrum of antimicrobial activity against microorganisms. However, the traditional method of prep...
Design and study of formulation variables affecting drug loading and its release from Alginate beads
ISSN:0975-1459 The development of alginate beads as a drug carrier system is considered to be more attractive because of its biocompatibility, mucoadhesive property, and its ability to deliver drug particularly in the intestinal pH. The preparation of alginate beads by ionic gelation method avoids the usage of toxic organic solvents and considered to be relatively economical method. However its...
in this study, poly(ethylene-co-vinyl alcohol) (evoh) as a novel biocompatible polymeric scaffold was surface modified by succinylation to get evohs and further pegylated to improve structural properties using methoxypolyethylene glycol (5000 da) succinate (pegs) along with targeting with retinoic acid (ra) to get final modified active and passive targeted conjugate (pegs-evohs-ra) to evaluate ...
