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.Keywords: bacteria, attachment, nanophase, topography, metabolism Margaret R ParkMichelle K BanksBruce ApplegateThomas J WebsterDove Medical PressarticleMedicine (General)R5-920ENInternational Journal of Nanomedicine, Vol 2008, Iss Issue 4, Pp 497-504 (2008)
