Mixed gelatin-alginate gels are widely studied as encapsulating matrices. However, the dissolution of gelatin at mild temperatures (close to body temperature) imparts low stability for these systems, particularly as delivery matrices. In this context, collagen fiber arises as an alternative due to its water binding properties. Thus, the main objective of this work was to evaluate the effect of ...

Collagen and gelatin is widely used as bio-polymer materials and medical materials. Currently, the direction is more and more clear that collagen-like peptide produced by chemical synthesis, and recombinant collagen and gelatin produced in various expression system constructed by gene engineering technique substitute for these products prepared by traditional methods. Based on the characteristi...

Application of combining herbal medicine and biomedical material science to nerve regeneration is a new approach. In this study, we describe a novel use of purified genipin, which can be extracted from Gardenia jasminoides Ellis, fixing the gelatin to be an extracellular matrix for peripheral nerve regeneration. A 10-mm gap of rat sciatic nerve was created between the proximal and distal nerve ...

Information on the preparation and properties of starch/gelatin blend microparticles with and without crosslinking for drug delivery is presented. The blend microparticles were prepared by the water-in-oil emulsion solvent diffusion method. Glutaraldehyde and methylene blue were used as the crosslinker and the water-soluble drug model, respectively. The blend microparticles were characterized b...

Byproduct utilization is an important consideration in the development of sustainable processes. Whey protein isolate (WPI), a byproduct of the cheese industry, and gelatin, a byproduct of the leather industry, were reacted individually and in blends with microbial transglutaminase (mTGase) at pH 7.5 and 45 degrees C. When a WPI (10% w/w) solution was treated with mTGase (10 U/g) under reducing...

91 Biodegradable haemostats [Absorbable gelatin sponges] and Hydrogels are a part of modern wound management systems. Development of absorbable gelatin sponges, drug loaded sponges, hydrogels and drug loaded hydrogels for advanced wound management was investigated in this research project. The developed formulations were evaluated to determine their potential for advanced wound management as de...

We present a method for measuring forces in granular media experiments using photoelastic gelatin spheres, which is applicable for investigating the forces generated by organisms moving through noncohesive granular materials. We describe how to fabricate gelatin spheres with appropriate characteristics for high-sensitivity photoelastic measurements. We present a calibration methodology to relat...

Biomimetic coatings constituted of gelatin and nanocrystalline apatite were deposited on titanium substrates from a slightly supersaturated calcium phosphate (CaP) solution enriched with different amounts of gelatin. Although the biopolymer inhibits the crystallization of the inorganic phase, as shown by the reduction of the mean dimensions of the spherical aggregates and of the degree of cryst...
