Abstract: In one aspect, the invention provides a method for making a hydrophilic-silk composition. The method includes providing at least one strand of silk fiber, treating the silk fiber with an alkaline solution to provide at least one strand of degummed silk fiber, and treating the degummed silk fiber with a treatment solution to provide a hydrophilic-silk drophilic-silk composition. The degummed silk fiber or the hydrophilic-silk composition is further immobilized with at least one reagent to make a silk-based diagnostic composition. The invention provides a silk-based diagnostic composition made by the method of the invention, and a diagnostic device that comprises the silk-based diagnostic composition. In another aspect, the invention provides a method of making a diagnostic device. The method includes providing at least one strand of a diagnostic-fiber composition, providing at least one strand of a hydrophobic-fiber composition, inter-weaving the at least one strand of the diagnostic-fiber composition and the at least one strand of the hydrophobic-fiber composition. In one embodiment, the diagnostic-fiber composition and the hydrophobic-fiber composition are both based on silk.
