Application of nanotechnology to control bacterial adhesion and patterning on material surfaces
نویسندگان
چکیده
Bacterial adhesion and biofilm formation on surfaces raises health hazard issues in the medical environment. Previous studies of bacteria adhesion have focused on observations in their natural/native environments. Recently, surface science has contributed in advancing the understanding of bacterial adhesion by providing ideal platforms that attempt to mimic the bacteria's natural environments, whilst also enabling concurrent control, selectivity and spatial control of bacterial adhesion. In this review, we will look at techniques of how nanotechnology is used to control cell adhesion on a planar scale, in addition to describing the use of nanotools for cell micropatterning. Additionally, it will provide a general background of common methods for nanoscale modification enabling biologist unfamiliar with nanotechnology to enter the field.

متن کاملControl of bacterial biofilm growth on surfaces by nanostructural mechanics and geometry.
Surface-associated communities of bacteria, called biofilms, pervade natural and anthropogenic environments. Mature biofilms are resistant to a wide range of antimicrobial treatments and therefore pose persistent pathogenic threats. The use of surface chemistry to inhibit biofilm growth has been found to only transiently affect initial attachment. In this work, we investigate the tunable effect...

متن کاملModeling of Air Relative Humidity Effect on Adhesion Force in Manipulation of Nano-Particles and its Application in AFM
In this paper, the effect of air relative humidity and capillary force on contact geometry of surfaces based on JKR model by Atomic force microscopy was investigated in order to manipulate nano-particles. With transition from macro to nano-scale, the effect of surface forces becomes more significant in comparison with inertial force. Because contact mechanics models are based on surface energy ...
