Abstract: Disclosed herein is an article that includes a first plurality of spaced features. The spaced features are arranged in a plurality of groupings; the groupings of features include repeat units; the spaced features within a grouping are spaced apart at an average distance of about 1 nanometer to about 500 micrometers; each feature having a surface that is substantially parallel to a surface on a neighboring feature; each feature being separated from its neighboring feature; the groupings of features being arranged with respect to one another so as to define a tortuous pathway. The plurality of spaced features provide the article with an engineered roughness index of about 5 to about 20.

Abstract: Disclosed herein is a method comprising growing a shim by disposing a mandrel having an optional textured surface in an electrolytic bath, where the shim contains a negative image of the optional textured surface formed by electrolytic deposition of a metal; affixing the shim working-side down on a reference plane using a fixture; optically scanning the shim to reverse engineer a geometry of a non-working surface, where reverse engineering a geometry of the non-working surface includes developing a profile of the non-working surface and the thickness of the shim; and adding a material to the non-working surface of the shim via additive manufacturing to form a tool insert.

Abstract: Disclosed herein is a method of forming a mold comprising disposing a film having a textured surface on a support; where the support has a shape of an article to be manufactured; pressing the film onto the support to cover a surface of the support; disposing a backing on the film; separating the support from the backing; and molding a material in the backing. Disclosed herein too is a method comprising contacting a first mandrel with a first mold; where the first mold has a textured surface; texturing a surface of the first mandrel with the first mold; disposing the first mandrel in a die; disposing a first material in the die to contact the first mandrel; imparting a texture from the surface of the first mandrel onto the material to form a second mold; and disposing a texture from the second mold onto a second material; where the second material is different from the first material.

Abstract: Disclosed herein is a method comprising transporting a conduit and a template through a guide tube; the template being disposed on an outer surface of the conduit between the conduit and the guide tube; and transferring a texture from the template to the conduit as the conduit and the template are transported through the guide tube. Disclosed herein too is an apparatus comprising a guide tube; the guide tube being operative to facilitate a transfer of a pattern from a template to a conduit; a first feed spool and a first take-up spool for feeding the conduit through the guide tube and for taking up the conduit after it has travelled through the guide tube respectively; and a second feed spool and a second take-up spool for feeding the template through the guide tube and for taking up the template after it has travelled through the guide tube respectively.

Abstract: Disclosed herein is a method of forming a bioadhesion resistant article comprising extruding a material through a die bearing a pattern of protrusions such that the extruded material has a surface having a series of parallel splines above a base surface, and applying pressure with a first patterned template to the surface of the extruded material such that the series of parallel raised splines are formed into discrete raised segments of varying length; where the patterned template comprises grooves that are inclined at an angle α to the splines. The method further comprises applying pressure with a second patterned template to the surface of the extruded material, where the second patterned template contains grooves that are inclined at an angle β to the splines.

Abstract: An article includes a path that extends across at least a portion of a surface of the article, the path being defined by at least one channel that traverses at least a portion of the surface or a first plurality of spaced features disposed on or in at least a portion of the surface. The first plurality of spaced features are arranged in a plurality of groupings. The groupings of features comprise repeat units, where the spaced features within a grouping are spaced apart at an average distance of about 1 nanometer to about 500 micrometers to define a path that traverses the plurality of spaced features.

Abstract: Disclosed herein is an article including a substrate having at least one surface that has a texture and a first type of growing cells, wherein an average length of features that form the texture is operative to facilitate cell growth, cell orientation, cell morphology and cell differentiation. Disclosed herein too is a method including forming a first layer of a polymeric material on at least one surface of a substrate; texturing the first layer to form a textured first layer; and forming a first type of growing cells on the textured first layer, wherein an average length of features that form the textured first layer is operative to facilitate cell growth, cell orientation, cell morphology and cell differentiation.

Abstract: Generally, an intraocular implant having on the external surface a plurality of pattern surface elements disposed in spaced apart relation defining a tortuous pathway adapted to control a flow of fluid, or a flow of particles suspended in a fluid, or inhibits the growth or migration of cells. In particular, an intraocular implant which implanted between an intraocular lens and the surface of the posterior capsule of the eye inhibits growth or migration of residual lens epithelial cells after cataract surgery by providing structural barriers to reduce posterior capsule opacification of the eye.
