[Simultaneous immobilization] may be achieved by such means as covalent bonding of the enzymes to the same functionalized polymer or by entrapment of the catalysts within the same microspace of a crosslinked polymer, microcapsule, or membrane-dependent device.  1, record 1, English, - simultaneous%20immobilization

Procedure, based on the liquid surfactant membrane concept, for providing immobilized enzymes within a nonpermanent microcapsule. Enzyme immobilization is brought about by emulsifying an aqueous enzyme solution with a surfactant to form the liquid membrane encapsulated enzymes.  2, record 2, English, - liquid%2Dsurfactant%20membrane%20method

Record number: 2, Textual support number: 1 OBS

The major advantages of this procedure are the nonchemical nature of the method and its reversibility of immobilization. However, the possibility of loss of enzyme by diffusion, and the same diffusion phenomenon controlling passage of substrates and products through the liquid membrane via a solubility mechanism rather than size exclusion mechanism, can be a disadvantage.  1, record 2, English, - liquid%2Dsurfactant%20membrane%20method

Méthode d'immobilisation d'enzymes par micro-encapsulation qui consiste à soumettre des agrégats de phospholipides dispersés dans la solution enzymatique à la sonication : on obtient des sphérules constituées d'une double couche lipidique emprisonnant des gouttelettes d'enzyme en solution aqueuse. A l'inverse des autres techniques, la pénétration du substrat ne dépend pas alors de la taille des pores de la membrane mais de sa solubilité dans les constituants lipidiques.  2, record 2, French, - m%C3%A9thode%20des%20liposomes

Phenomenon of phase separation in polymer solutions. The formation of a microcapsule is dependent on the lower solubility of the polymer at the interface of a microdroplet. It is a physical phenomenon and has been employed for the preparation of semipermeable microcapsules used for immobilizing enzymes.  2, record 3, English, - coacervation

One purification method for polymers involves dissolving the polymer in an organic solvent and reprecipitating it by adding another organic solvent which is miscible with the first but which does not dissolve the polymer. In this treatment, if the temperature and the amount of organic solvent added are varied, the polymer solution can be separated into two phases containing low and high concentrations of polymer.... This ... phase separation method for microencapsulation is an application of coacervation.  3, record 3, English, - coacervation

Le phénomène de co-acervation a été appliqué au fractionnement des substances macromoléculaires en utilisant le fait que la phase coacervée contient les macromolécules de degrés de polymérisation les plus élevés et la phase surnageante celles des plus faibles degrés de polymérisation.  2, record 3, French, - co%2Dacervation

Les liposomes sont des particules artificielles minuscules possédant la propriété de traverser les membranes cellulaires. En les utilisant comme transporteurs de médicaments anticancéreux, une équipe de Los Angeles vient d'obtenir des résultats encourageants dans le traitement d'une tumeur redoutable observée principalement chez les malades atteints du sida : le sarcome de Kaposi.
