摘要：

Colloidal gas aphrons are microbubbles encapsulated by surfactant multilayers. They provide a large interfacial area to adsorb charged and/or hydrophobic molecules; the extent and mechanism of the adsorption depends on the surfactant multilayer. The physical properties of colloidal gas aphrons have recently been characterized for a range of surfactants in order to find the best systems for particular applications. A range of exciting biotechnology applications has been identified, including the recovery of cells, proteins and other biological molecules, and the enhancement of gas transfer in bioreactors and bioremediation.
