TLDR
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.Abstract:
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 fluorescens 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 fluorescens 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.read more

Effect of micro- and nanoscale topography on the adhesion of bacterial cells to solid surfaces.
TL;DR: The attachment of key microorganisms, including Escherichia coli, Listeria innocua, and Pseudomonas fluorescens, to silica and alumina surfaces with micron and nanoscale topography was investigated and suggest that orientation of the attached cells occurs preferentially such as to maximize their contact area with the surface.

Enhanced functions of osteoblasts on nanophase ceramics
TL;DR: The results of the present study provided the first evidence of enhanced long-term (on the order of days to weeks) functions of osteoblasts cultured on nanophase ceramics, and clearly represent a unique and promising class of orthopaedic/dental implant formulations with improved osseointegrative properties.

Specific proteins mediate enhanced osteoblast adhesion on nanophase ceramics
TL;DR: Select enhanced osteoblast adhesion was independent of surface chemistry and material phase but was dependent on the surface topography (specifically on grain and pore size) of nanophase ceramics.

Nantotechniques and approaches in biotechnology
TL;DR: This article concentrates mainly on surface-directed nanobiotechnologies because they are nearer to commercial realisation, such as use in tissue engineering, control of biofouling and cell culture, than those directed at producing nanoparticles.
