Asakura and Oosawa described four cases in which depletion forces would occur. They first described the most general case as two solid plates in a solution of macromolecules. The principles for the first case were then extended to three additional cases. Visualizza altro A depletion force is an effective attractive force that arises between large colloidal particles that are suspended in a dilute solution of depletants, which are smaller solutes that are preferentially excluded from the … Visualizza altro Sterics The system of colloids and depletants in solution is typically modeled by treating the large … Visualizza altro Derjaguin approximation Theory Asakura and Oosawa assumed low concentrations of macromolecules. However, at … Visualizza altro Depletion forces have been observed and measured using a variety of instrumentation including atomic force microscopy, optical tweezers, and hydrodynamic force balance machines. Atomic force microscopy Atomic force microscopy Visualizza altro Depletion forces were first described by Sho Asakura and Fumio Oosawa in 1954. In their model, the force is always considered to … Visualizza altro The original Asakura–Oosawa model considered only hard-core interactions.
