The gastrointestinal track has different pH values at sections. Thus, it is not easy to carry a drug the colon for absorption. sensitive polymeric macrosphere carriers have important advantages such as being able be taken orally, targeting active ingredient desired area and dosing concentration long time in target area. In this contex sodium alginate-gelatin macrospheres were produced by disper...

Development of technology driven functional and natural health products has a number of challenges since bioactive ingredients incorporated are unstable to processing with reduced absorption, low bioavailability and reduced shelf life. Encapsulation offers a great potential for protecting and delivering bioactive components and micro-organisms through technology driven products to enhance human...

We report the effect of neutral macromolecular crowders poly(ethylene glycol) (PEG) (8 kDa) and Ficoll (70 kDa) on liquid-liquid phase separation in a polyuridylic acid (polyU)/spermine complex coacervate system. The addition of PEG decreased both the amount of spermine required for phase separation and the coacervation temperature (TC). We interpret these effects on phase behavior as arising d...
