Low viscosity hydrogel of guar gum: Preparation and physicochemical characterization

Untitled

“…[122] Green tea polyphenol epigallocatechin-3-gallate was incorporated into a carbohydrate matrix of GA and maltodextrin with an encapsulation efficiency of approximately 85% is also used against colon cancer. [123] Polysaccharide NPs are used to deliver natural antioxidants capable of inhibiting steps of the tumorigenesis process for its chemoprevention. [123] GA glycoprotein -functionalized AuNPs possess optimum sizes (12-18 nm core diameter and 85 nm hydrodynamic diameters) that target individual tumor cells and penetrate through tumor vasculature and pores.…”

[123] GA glycoprotein -functionalized AuNPs possess optimum sizes (12-18 nm core diameter and 85 nm hydrodynamic diameters) that target individual tumor cells and penetrate through tumor vasculature and pores. These NP GA-198AuNPs are biocompatible and show high tumor affinity in severely compromised immunodeficient mice bearing human prostate tumor xenografts.…”

Desktop Robot Based Rapid Prototyping System: An Advanced Extrusion Based Processing of Biopolymers into 3D Tissue Engineering Scaffolds

“…There are very few reports on any RP technology producing scaffolds with consistent pore definition in the range of 200-400 µm, while also retaining a high accuracy of outside architecture (Maher et al, 2009a(Maher et al, & 2009b. Hydrogel with low viscosities tend to be difficult to use when constructing scaffolds because of the long gelation time which results in the collapse of scaffolds due to their mechanical instability (Cunha et al, 2005).

Quantification of Sugar Epimers in Polygalactomannans by ESI-MS/MS

“…The interest in these polymers is mainly due to the possibility of obtaining solutions with unique rheological properties, like extreme viscosities and nonNewtonian behavior [13][14][15]. PGMs are often subjected to chemical reactions (e.g., hydroxyalkylation, carboxymethylation) [16,17] or enzymatic treatments (e.g., depolymerization by β-mannanase, oxidation by laccase or galactose oxidase) [18][19][20], in order to modify their solubility and viscoelastic properties, or to obtain hybrid, functionalized materials [21,22].…”
