Percolation Behavior of Nonionic Reverse Micellar Solution

Activity and stability of catalase in nonionic micellar and reverse micellar systems.

Catalase activity and stability in the presence of simple micelles of Brij 35 and entrapped in reverse micelles of Brij 30 have been studied. The enzyme retains full activity in aqueous micellar solution of Brij 35. Catalase exhibits "superactivity" in reverse micelles composed of 0.1 M Brij 30 in dodecane, n-heptane or isooctane, and significantly lowers the activity in decaline. The incorpora...

Reverse Micellar Encapsulation of AZT Using Carbohydrate Derived Nonionic Gemini Surfactants in Non-Polar Media

The carbohydrate derived nonionic gemini surfactants have been emerged as a result of our present day interest in environmentally compatible chemicals. Reverse micelles formed by surfactants can be used for selective solubilization and reactions which exploit their nanometer size, micro-environments and mimics the membranous biological system. Novel carbohydrate based non-ionic gemini surfactan...

A New Thermodynamic Approach for Protein Partitioning in Reverse Micellar Solution

Reverse micellar systems are nanofluids with unique properties that make them attractive in high selectivity separation processes, especially for biological compounds. Understanding the phase behavior and thermodynamic properties of these nanosystems is the first step in process design. Separation of components by these nanosystems is performed upon contact of aqueous and reverse micellar phase...

Kinetics of nonionic surfactant adsorption at a fluid-fluid interface from a micellar solution.

Investigation on the precipitation, microenvironment and recovery of protein in CO2-expanded reverse micellar solution

The effect of compressed CO2 on the properties of protein (trypsin) in the reverse micelles of sodium bis(2-ethylhexyl)sulfosuccinate AOT/decane/water has been studied. UV-vis spectrum was used to determine the precipitation of trypsin in the reverse micelles, which reveals that trypsin can be precipitated from the reverse micelles by compressed CO2 at suitable pressures, while the surfactant A...
