New Coating Materials Based On Mixtures of Shellac and Pectin for Pharmaceutical Products
Shellac is a natural polyester resin secreted by insects. Pectins are natural, non-toxic and water-soluble polysaccharides extracted from the peels of citrus fruits or the leftovers of apples. Both polymers are allowed for the use in the pharmaceutical industry and as a food additive. SSB Aquagold® is the aqueous solution of shellac and can be used for a coating process as an enteric or control...
متن کاملSealing liquid-filled pectinate capsules with a shellac coating.
Liquid-filled pectinate capsules have a large potential for the controlled and site-specific delivery of liquid drugs. Earlier studies have shown that pure pectinate capsules can store drugs only for a few minutes. Here, we show that the retention time can be extended to several hours by coating the capsules with the natural resin shellac. A bilberry extract containing anthocyanins with promisi...
متن کاملOsteogenic Surface Modification Based on Functionalized Poly-P-Xylylene Coating
The biotechnology to immobilize biomolecules on material surfaces has been developed vigorously due to its high potentials in medical applications. In this study, a simple and effective method was designed to immobilize biomolecules via amine-N-hydroxysuccinimide (NHS) ester conjugation reaction using functionalized poly-p-xylylene coating on material surfaces. The NHS ester functionalized coat...
متن کاملBroadband omnidirectional antireflection coating based on subwavelength surface Mie resonators
Reflection is a natural phenomenon that occurs when light passes the interface between materials with different refractive index. In many applications, such as solar cells or photodetectors, reflection is an unwanted loss process. Many ways to reduce reflection from a substrate have been investigated so far, including dielectric interference coatings, surface texturing, adiabatic index matching...
متن کاملOptimal Surface Coating
The short-term clinical failures of cementless stems, such as proximal bone resorption and thigh pain, have limited their acceptance despite the potential long-term benefits of biological fixation for younger and more active patients. The clinical problems are believed to be related to failure at the bone-stem interface. By optimizing the design of the prosthesis to prevent or minimize failure ...
