Enzymes can be immobilized within microcapsules that have either a permanent or nonpermanent semipermeable membrane.... Nonpermanent membranes or "liquid-surfactant membranes"... refer to a water-immiscible phase composed of surfactants, "additives", and a hydrocarbon solvent that contain emulsion-size aqueous droplets of various reagents or catalysts.... The general procedure for immobilizing enzymes with liquid-surfactants membranes microcapsules is similar to that used for microencapsulation with permanent membranes. The aqueous enzyme-containing solution is emulsified with a surfactant to form the liquid membrane encapsulated enzyme. Once prepared, the microcapsules are transferred to an aqueous solution to which then can be added the substrate.  2, record 2, English, - liquid%2Dsurfactant%20membrane%20microcapsule

Les microcapsules à membrane liquide [...] présentent l'intérêt de pouvoir être très facilement préparées et de permettre la récupération du matériau enzymatique par simple rupture. Ainsi lorsque l'on soumet à des ultrasons des agrégats obtenus par dispersion de phospholipides dans l'eau, on donne naissance à des sphères closes limitées par une double couche lipidique [...], les liposomes [...], emprisonnant des gouttelettes d'enzymes en solution aqueuse.  2, record 2, French, - microcapsule%20%C3%A0%20membrane%20liquide

À 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.  3, record 2, French, - microcapsule%20%C3%A0%20membrane%20liquide

Il est souvent délicat de contrôler avec précision la position de l'objet étudié en raison de sa taille et de sa fragilité. Cela devient plus délicat encore lorsqu'il s'agit d'approcher deux objets initialement séparés afin de les amener au contact. Pour réaliser de telles expériences, nous développons des outils spécifiques de manipulation : le piégeage optique par faisceaux laser et la micromanipulation mécanique. Le piégeage optique utilise la pression de radiation exercée par un ou deux faisceaux laser focalisés. On peut ainsi manipuler sans contact des objets de quelques microns. Nous utilisons cette technique pour mettre en contact une particule solide avec une vésicule géante.  1, record 5, French, - pi%C3%A9geage%20optique
