Composite biomaterials based on proteins and inorganic fillers are highly attractive for wound dressing applications due to their highly absorbent properties towards blood and exudate provided by the inorganic fillers. Moreover, such composites offer a desirable environment for cells due to the combination of organic and inorganic characteristics. This study highlights the fabrication of soy protein isolate/nanoscale bioactive glass composite films by solvent casting method as a matrix for wound-dressing applications. The effect of the addition of bioactive glass nano particles on blood clotting was assessed. Cytotoxicity and in vitro cytocompatibility of the films were also tested. The results showed that the composite films could meet the essential requirements for an appropriate wound dressing with additional favorable properties such as hemostatic capability and mechanical properties as well as significant cell cytocompatibility.

“…Cu and Zn nanocluster as well as silicon oxides nanoparticles have been incorporated in SPI matrices to get the reinforced SPI material with improved properties [5,6]. Carbon nanotubes (CNTs) [7], chitin whiskers [8], layered silicate [9][10][11], carbon nanoparticles [12] and silica nanoparticles [13] have been explored as reinforcement materials for SPI. In addition to single composite SPI film, Liu et al has incorporated chitosan and halloysite nanotubes in SPI to fabricate eco-friendly hybrid composite SPI film with high tensile strength [14].…”

ZnSe nanoparticles have been synthesized by microwave assisted method by using zinc chloride, selenium powder and ethylene diamine. The synthesized nanoparticles have been characterized structurally by FT-IR and XRD as well as morphological characterization was done by scanning electron microscope (SEM). The crystallite size after synthesis was obtained around 30 nm for pure ZnSe nanocrystallites. However, from SEM micrograph, agglomerated ZnSe nanoparticles of irregular shapes were observed. The assynthesized ZnSe nanoparticles at different contents (1 to 5% w/w w.r.t SPI) were incorporated into soy protein isolate (SPI) to produce reinforced SPI films by solution casting method. The ZnSe nanoparticles incorporated SPI suspensions were subjected to molecular mass and specific conductivity studies. Neat and ZnSe nanoparticles incorporated SPI films were structurally and mechanically characterized by FT-IR and tensile properties, respectively. Transmittance and water uptake studies were also carried out for ZnSe nanoparticles incorporated SPI films. The tensile strength and modulus increased from 5.80 MPa to 10.06 MPa and 18.84 MPa to 94.70 MPa with the increase in the contents of ZnSe nanoparticles from 0 to 5%. Moreover, the results also revealed a good antibacterial effect in ZnSe nanoparticles incorporated SPI film. The main application of nanoparticles incorporated SPI film will be in the area of biodegradable packaging.

Addition of microcapsules with a high dielectric constant and low specific heat capacity to a battered layer was designed to create a higher temperature in the crust than in the prefried fish nuggets to prevent the water vapor in the fish nuggets from migrating to the crust during microwave heating. Therefore, chitosan-silica hybrids and soybean oil were utilized to prepare the shell and core of the thermally stable microcapsules (MC(CS)), respectively. The MC(CS) were prepared by sol-gel coacervation from an oil-in-water emulsion. The sodium silicate was hydrolyzed and coacervated through polymerization for 24 h at pH 5. The zeta potential analysis indicated that chitosan with a positive charge and silica with a negative charge interacted through electrostatic attraction to form a hybrid shell. The volume mean particle size and encapsulation efficiency of the MC(CS) were 9.6 ± 0.2 μm and 75.6% ± 1.3%, respectively, when oil/chitosan = 0.2 and chitosan/silica = 0.5 (w/w). In addition to H-bonding and electrostatic attraction, Si-O-N bonds were formed between chitosan and silica. Dehydration of the bound water in the MC(CS) was observed in the range of 25 to 250 °C in the differential scanning calorimetry thermal analysis, with the lack of apparent thermal peaks indicating its high thermal stability. The decrease of force to cut the crust observed by texture analysis as well as the increase of hedonic score by consumer acceptance test revealed the addition of 1% MC(CS) significantly improved the crispness of the crust in the microwave-reheated nuggets.
