NOVELTY - A coating method involves placing a substrate and a biomolecule in a chamber and applying a vapor deposition process within the chamber so as to form a solid deposition of the biomolecule on at least a portion of a surface of the substrate.    USE - For vapor depositing biomolecules e.g. proteins, peptide, a nucleic acid, a nucleotide or an amino acid onto to substrates to form composition used in articles particularly a medical device adapted for implantation in a subject, a sensor device, an electrical energy storage device, a self-cleaning surface or microfluidic device (claimed), in capillary electrophoresis, isoelectric focusing, immunoassays, flow cytometry, sample injection of proteins for analysis via mass spectrometry, sample injection of air or water samples for analysis via flamespectrometry, polymerase chain reaction (PCR) amplification, DNA analysis, cell manipulation, cell separation, cell patterning and chemical gradient formation. The biomolecules also includes carbohydrates, saccharides and polysaccharides of various lengths, lipids, hormones, vitamins, antibiotics and other bioactive agents. The self-cleaning surface includes transparent objects such as window glass, solar cell panels, glassware, lenses.    ADVANTAGE - Vapor deposition has not been employed to coat substrates with biomolecules, particularly since many biomolecules, such as peptides and proteins, are sensitive to the physical conditions employed during the process. The present method for the first time enables transforming sample of biomolecules into a vaporized or gaseous state while maintaining the biological properties of the biomolecules in the sample. This ability to transform the biomolecules to a vaporized or gaseous state facilitates their deposition on the surface of a solid substrate, in the form of a solid deposition of nanostructures on the surface. The solid deposition of such nanostructures results in nanostructures of biomolecules possessing superior physical, chemical and thermal stability as well as remarkable mechanical rigidity. Additionally, the nanostructures also have favorable physical properties such as electronic properties, dielectric properties, electrochemical properties, hydrophobic or hydrophilic properties, etc. The solid deposition surface also possesses high activity and density rate, high heat dissipation rate and/or high dispersion rate. Additionally, the nanostructures in the solid deposition facilitate quantum sizing effect, micro sizing effect, surface effect and/or macroscopic quantum tunneling. Such properties make the solid deposition surface useful in production of cells having high charging current that allows fast charging of the energy storage devices.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following    (1) a composition comprising a solid substrate and at least one type of a biomolecule deposited on its surface by vapor deposition at a predetermined pattern which comprises several distinct addressable locations; and    (2) an article comprising a solid deposition of a biomolecule, formed by vapor deposition and devoid of any solid substrate attached to it.
