Embodiment Construction

[0036]Disclosed herein are various scaleable surface topography for modifying biodeposition, i.e. bioadhesion, such as biofouling organisms including but not limited to algae, bacteria, fungi , mold and barnacles. As described in the examples described below, it has been demonstrated through experimental testing that the surface topography according to the present invention provides a passivated and non-toxic surface which, by choosing appropriate feature sizes and spacings, can be significantly and generally larger. Significantly reduced settling and adhesion of most co-fouling microorganisms.

[0037] While not required to practice the invention, applicants provide the following, which applicants do not intend to be bound by an institution believed to be capable of operation to demonstrate the efficacy of the invention. Surface efficacy according to the invention may be due to physical interference with the settling and adhesion of microorganisms such as algae, bacteria and...

Abstract

An article has a surface topography for resisting bioadhesion of organisms and includes a base article having a surface. A composition of the surface includes a polymer. The surface has a topography comprising a pattern defined by a plurality of spaced apart features attached to or projected into the base article. The plurality of features each have at least one microscale dimension and at least one neighboring feature having a substantially different geometry, wherein neighboring patterns share a common feature. The surface has an optical transmission at 400 nm to 700 nm of equal to or greater than 70%. In one embodiment, the surface can comprise a coating layer disposed on the base article.

Description

technical field [0001] The present invention relates to articles and related devices and systems having surface topography and / or surface elastic properties for providing non-toxic bioadhesion control. Background technique [0002] Environmental surfaces are frequently contaminated with microorganisms. These organisms can be deposited on a surface via contact transfer from another contaminated surface or via airborne organisms that settle and attach to the surface. Contamination of environmental surfaces can spread disease, thereby becoming a burden on human health. Toxins including bleach, ammonia, and other common cleaners can be used to disinfect surfaces. However, surfaces are susceptible to re-contamination between cleanings. [0003] The accumulation of bacteria, ie biofilms, on implanted devices such as catheters poses a serious risk of infection leading to serious complications such as death. Bacterial contamination is also a problem for materials utilized in opt...
