“…These have been attributed to the contribution of sedimentation phenomena at lower flow rates [35] and to presence of surface appendages, e.g. flagellum, which may have a positive effect on adhesion, a feature that is also not considered in this model [39].…”

“…flagellum, which may have a positive effect on adhesion, a feature that is also not considered in this model [39]. Li, et al [35] have studied the contribution of sedimentation to mass transport in a PPFC using S. aureus and a glass surface. Having tested stagnant conditions and flow rates up to 0.33 ml.s -1 , these authors have shown that when accounting for sedimentation in calculating deposition efficiencies, these decrease with increasing flow rates.…”

The adhesion of Escherichia coli to glass and polydimethylsiloxane (PDMS) at different flow rates (between 1 and 10 ml.s -1 ) was monitored in a parallel plate flow chamber in order to understand the effect of surface properties and hydrodynamic conditions on adhesion. Computational fluid dynamics was used to assess the applicability of this flow chamber in the simulation of the hydrodynamics of relevant biomedical systems. Wall shear stresses between 0.005 and 0.07 Pa were obtained and these are similar to those found in the circulatory, reproductive and urinary systems. Results demonstrate that E.coli adhesion to hydrophobic PDMS and hydrophilic glass surfaces is modulated by shear stress with surface properties having a stronger effect at the lower and highest flow rates tested and with negligible effects at intermediate flow rates. These findings suggest that when expensive materials or coatings are selected to produce biomedical devices, this choice should take into account the physiological hydrodynamic conditions that will occur during the utilization of those devices.

The significance of nanofiltration membrane surface properties when interacting with microbeads with and without permeate flux was investigated. This was achieved by characterising the surface tension and zeta potential of micro beads and NF90 membranes to determine the colloid-membrane interaction forces. Dynamic adhesion assays under different ionic strengths (0.1M and 0.01M) and pH (5, 7, 9) were conducted. Experimental results showed that at high ionic strength, pH does not have a significant effect on adhesion rates, while at low ionic strength the adhesion rate increased at pH 7 (4.56 s -1 cm -2 ) compared to pH 5 and pH 9, with rates of 2.69 and 3.
