A medical device (10) includes a structure (12) adapted for introduction into a patient, the structure (12) being formed of a preferably non-porous base material (14) having a roughened or textured surface (16). The structure (12) is conveniently configured as a vascular stent with a base material (14) of stainless steel, nitinol or another suitable material. The medical device (10) also includes a layer (18) of a bioactive material posited directly upon the roughened or textured surface (16) of the base material (14) of the structure (12). The surface (16) of the base material (14) is roughened or textured by etching or by abrasion with sodium bicarbonate or another suitable grit. A preferred roughened or textured surface (16) is thought to have a mean surface roughness of about 10 μin. (about 250 nm) and a surface roughness range between about 1 μin. and about 100 μin. (about 25 nm and about 2.5 μm). The particularly preferred use of sodium bicarbonate as the abrasive to provide roughness or texture to the surface (16) of the base material (14) of the structure (12) is additionally advantageous in the low toxicity of the sodium bicarbonate to production workers, the ease of product and waste cleanup, and the biocompatibility of any residual sodium bicarbonate.

Methods for preparing a biochip are provided herein wherein the biomolecular probe to be used with the biochip is alternatively bound to a hydrogel prepolymer prior to or simultaneously with polymerization of the prepolymer. In particularly preferred embodiments, a polyurethane-based hydrogel prepolymer is derivatized with an organic solvent soluble biomolecule, such as a peptide nucleic acid probe in aprotic, organic solvent. Following derivatization of the prepolymer, an aqueous solution, for example sodium bicarbonate, preferably buffered to a pH of about 7.2 to about 9.5, is added to the derivatized prepolymer solution to initiate polymerization of the hydrogel. Alternatively, a water soluble biomolecule, such as DNA or other oligonucleotide, is prepared in an aqueous solution and added to the polyurethane-based hydrogel prepolymer such that derivatization and polymerization occur, essentially, simultaneously. While the hydrogel is polymerizing, it is microspotted onto a solid substrate, preferably a silanated glass substrate, to which the hydrogel microdroplet becomes covalently bound. Most preferably the hydrogel microdroplets are at least about 30 mum thick, for example about 50 mum to about 100 mum thick. The resulting biochips are particularly useful for gene discovery, gene characterization, functional gene analysis and related studies.
