Fragrance release profile from sonochemically prepared protein microsphere containers.
Protein microspheres have been prepared by sonicating a mixture of pure fragrant oil (amyl acetate (AA)) with an aqueous protein (bovine serum albumin) solution. The prepared protein spheres are nano- to micrometer sized with an encapsulation efficiency of approx. 97% for the AA present on the surface and inside the BSA capsule. Containers were found stable for more than 6 months when stored se...
متن کاملCharacterization of sonochemically prepared proteinaceous microspheres
Aqueous suspensions of albumin and haemoglobin microspheres can be synthesized using high-intensity ultrasound. The particle size distributions are Gaussian with mean diameters of a few micrometers. These microspheres can contain either nonaqueous liquids (i.e. microcapsules) or air (i.e. microbubbles). The chemical processes involved in the synthesis and some physical properties of the microsp...
متن کاملEncapsulation and release of aqueous components from sonochemically produced protein microspheres.
Aqueous solutions of salts or dyes have been contained in sonochemically produced lysozyme microspheres by encapsulating an inverse emulsion in tetradecane. Release can be triggered by chemically disrupting crosslinking in the protein shell or by mechanical disruption using high intensity ultrasound.
متن کاملProtein disulphide isomerase-induced refolding of sonochemically prepared Ribonuclease A microspheres.
The present communication describes for the first time the development of Ribonuclease A (RNase A) microspheres using the sonochemical method followed by an enzymatic treatment with protein disulphide isomerase (PDI). Ultrasound application induced changes on the protein physicochemical and biological properties: the enzymatic activity of RNase A was decreased in 35% and the free thiol groups c...
متن کاملFragrance release from the surface of branched poly (amide)s.
Enzymes are powerful tools in organic synthesis that are able to catalyse a wide variety of selective chemical transformations under mild and environmentally friendly conditions. Enzymes such as the lipases have also found applications in the synthesis and degradation of polymeric materials. However, the use of these natural catalysts in the synthesis and the post-synthetic modification of dend...
