Deposition of Charge-regulated Biocolloids on a Charged Surface

摘要：

The deposition of charge-regulated particles onto a charged plate is modeled theoretically. The phenomenon considered mimics the attachment of biological cells onto a surface. The influences of the parameters key to the problem under consideration are examined through numerical simulation. We show that the following conditions lead to a faster rate of deposition: (a) the ratio (bulk concentration of H + /equilibrium constant of the surface functional groups) is high. (b) The energy barriers for the three cases examined rank as (constant surface potential)<(charge-regulation)<(constant surface charge density), and the rates of deposition of particles follow the reverse order.
