Immobilization of rapeseed press-cake in an alginate matrix for the sorption of atrazine

Urs von Stockar, Ian William Marison, Véronique Breguet, Julien Boucher

Due to residual oil retained within it, rapeseed press-cake has been shown to be effective for the removal of atrazine from water through an absorption mechanism. However, it is difficult to put this into practice due to the hygroscopic nature of the press ...

Enzymatic hydrolysis of organic-core microcapsules to produce aqueous-core microcapsules

Urs von Stockar, Ian William Marison, Véronique Breguet

This paper describes the development of a new method to obtain aqueous-core microcapsules from organic-core capsules. The direct production of microcapsules, using tripropionin as organic material, followed by the hydrolysis of the core by a lipase was inv ...

Alginate-based microcapsules for mammalian cell culture and other biotechnological applications

Véronique Breguet

Since life began, nature has been using the envelopment of systems for their protection or for providing a particular reaction space, the enveloping wall displaying additional specific membrane functions. The abundance of examples is quite overwhelming and ...

Formation of Microcapsules from Polyelectrolyte and Covalent Interactions

Urs von Stockar, Ian William Marison, Véronique Breguet, Raphaël Gugerli, Mimma Pernetti

A new approach combining electrostatic and covalent bonds was established for the formation of resistant capsules with long-term stability under physiol. conditions. Three kinds of interactions were generated in the same membrane: (1) electrostatic bonds b ...
