The encapsulation of living mammalian cells within a semi-permeable hydrogel matrix is an attractive procedure for many biomedical and biotechnological applications, such as xenotransplantation, maintenance of stem cell phenotype and bioprinting of three-dimensional scaffolds for tissue engineering and regenerative medicine. In this review, we focus on naturally derived polymers that can form h...

Monolayer films based on cassava starch (CS) or maize (MS), with and without 10% of gellan xanthan gum, PLA-PHBV (75:25) blend films, were obtained by melt-blending compression moulding, using glycerol (for blends) PEG 1000 polyester as plasticisers. Bilayer thermo-compression the different sheets sheet. Both mono bilayers characterised to their mechanical barrier properties, equilibrium moistu...

oral ph sensitive drug delivery systems are of utmost importance as these systems deliver the drug at specific part of the gastrointestine (gi) as per the ph of gi, resulting in improved patient therapeutic efficacy and compliance. the ph range of fluids in various segments of the gi tract may provide environmental stimuli for drug release. the aim of this study was to design buoyant beads cont...
