Our previous study, on a functionalized glass surface to covalently immobilize antibodies, was conducted to produce a more efficient means of water contamination analysis. The current methods used to detect organisms in water require up to 4 days to produce results that are indicative of only a small number of potential contaminates. Enzyme linked immunosorbent assays (ELISA) can use immunological methods to detect a wide range of biomolecules in less time than the current methods. However, traditional ELISAs produce a significant amount of solid waste and require many high-purity antibodies. The costs incurred and biologically- contaminated waste produced by ELISAs have led to the production of a smaller alternative called a microarray. Microarrays use immobilized biomolecules (proteins, lipids, antibodies, and carbohydrates) to detect conjugate biomolecules in solution. Multiple types of biomolecules can be printed onto a single solid glass or polymer substrate to detect multiple conjugate molecules in a single test. Our previous work focused on modification of a glass substrate to increase the surface area available for immobilization and the means by which antibodies were bound to the surface. Covalent immobilization of the antibodies instead of hydrophobic binding is one method that can optimize the binding concentration of antibodies onto the substrate. Our results indicated that surface modifications we made to glass substrates successfully immobilized antibodies. However, the immobilized antibodies denatured, and did not retain their functionality after the immobilization process. Stabilization of the antibodies structure is a potential solution to prevent the denaturing caused during immobilization.
