Abstract
Disclosed is a medical device having a substrate having an exposed surface and a texture over at least part of the exposed surface. The texture includes a plurality of nanofeatures that inhibit bacterial adhesion on the surface and that also inhibit bacterial growth on the surface and have a size range between about 0.01 nanometers and about 1,000 nanometers. The texture can include a plurality of nanofeatures applied thereto such that the texture has a first particle size at a first location, a second particle size at a second location, and a gradient of particle size from the first particle size to the second particle size between the first location and the second location.
Claims22
A medical device comprising:
- a substrate having an exposed surface;
- and
- a texture over at least part of the exposed surface, the texture comprising a plurality of nanofeatures, the nanofeatures inhibiting bacterial adhesion on the surface,
- wherein the nanofeatures are formed on the substrate, and
- wherein the nanofeatures comprise a first size range on the substrate and a second size range, smaller than the first size range, on top of the first size.
A medical device comprising:
- a substrate having an exposed surface;
- and
- a texture over at least part of the exposed surface, the texture comprising a plurality of nanofeatures, the nanofeatures inhibiting bacterial adhesion on the surface,
- wherein the plurality of nanofeatures comprise a first plurality of nanoparticles having a first size range attached to the surface and a second plurality of nanoparticles having a second size range, different from the first size range, on top of the first plurality of nanoparticles.
