“…16,19 However, for transcutaneous devices such as catheters, the time frame for biofilm formation is typically 14 days. 7 Thus, the focus of this study was to test the effects of an engineered microtopography on bacterial colonization and biofilm formation for a period of time that extended beyond 14 days.…”

“…There appears to be a trend toward increased bacterial coverage as the R a -roughness values increased on electropolished steel. 19 Conversely, P. aeruginosa was less likely to foul hydrophilic, electrically neutral, smooth polymeric surfaces. 20 Interestingly, bacterial adhesion was reduced on stainless steel surface microtopographies that were generated by a one-directional polishing finish relative to smooth surfaces.…”

“…Bacterial adhesion is, thus, affected by surface properties (Litzler et al 2007;Schildhauer et al 2007) such as hydrophobicity (Schackenraad et al 1992;Bos et al 2000;Karakeçili and Gümü derelioglu 2002), hydrophilicity (Kiss et al 1996;Gomez-Suarez et al 2002), steric hindrance (Kuhl et al 1994;Rijnaarts et al 1999), and surface roughness (Medilanski et al 2002;Whitehead et al 2006). There is a positive correlation between protein adsorption and short-term bacterial attachment with surface property changes (Cunliffe et al 2003).…”

Surfaces with nanophase compared to conventional (or nanometer smooth) topographies are known to have different properties of area, charge, and reactivity. Previously published research indicates that the attachment of certain bacteria (such as Pseudomonas fl uorescens 5RL) is higher on surfaces with nanophase compared to conventional topographies, however, their effect on bacterial metabolism is unclear. Results presented here show that the adhesion of Pseudomonas fl uorescens 5RL and Pseudomonas putida TVA8 was higher on nanophase than conventional titania. Importantly, in terms of metabolism, bacteria attached to the nanophase surfaces had higher bioluminescence rates than on the conventional surfaces under all nutrient conditions. Thus, the results from this study show greater select bacterial metabolism on nanometer than conventional topographies, critical results with strong consequences for the design of improved biosensors for bacteria detection.

“…The presence of large surface defects on NF and RO membranes are areas larger than those featured in the minimum value of surface roughness presenting areas with lower shear rate. Microscale surface defects on other types of surfaces, such as stainless steel [22,23] have been found to influence bacterial adhesion [24][25][26][27]. Moreover, a previous study has demonstrated preferential bacterial adhesion to substrates comprised of surface topographical heterogeneities compared to flat surfaces [28].…”

The role of the physicochemical and surface properties of NF/RO membranes influencing bacterial adhesion has been widely studied. However, there exists a poor understanding of the potential role membrane topographical heterogeneities can have on bacterial adhesion. Heterogeneities on material surfaces have been shown to influence bacterial adhesion and biofilm development. The purpose of this study was therefore to investigate whether the presence of membrane topographical heterogeneities had a significant role during bacterial adhesion as this could significantly impact on how biofouling develops on membranes during NF/RO operation. An extensive study was devised in which surface topographical heterogeneities from two commercial membranes, NF270 and BW30, were assessed for their role in the adhesion of two model organisms of different geometrical shapes, Pseudomonas fluorescens and Staphylococcus epidermidis. The influence of cross-flow velocity and permeate flux was also tested, as well as the angle to which bacteria adhered compared to the flow direction. Bacterial adhesion onto the membranes and in their surface topographical heterogeneities was assessed using Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM), fluorescence microscopy and image analysis. Results showed that up to 30% of total adhered cells were found in membrane defect areas when defect areas only covered up to 13% of the membrane surface area. This suggests that topographical heterogeneities may play a significant role in establishing environmental niches during the early stages of biofilm development. Furthermore, no noticeable difference between the angle of cell attachment in defect areas compared to the rest of the membrane surface was found.
