Claim Text:
1. An apparatus for isolating biological molecules from a sample, comprising: a substrate having a surface configured to adsorb a plurality of types of biological molecules, wherein the plurality of types of biological molecules comprises at least nucleic acids and proteins; a plurality of reservoirs, wherein each reservoir of the plurality of reservoirs houses a solution adapted to extract a specific type of biological molecule from the sample and to enhance adsorption of the specific type of biological molecule to the surface, and each solution housed in a respective reservoir of the plurality of reservoirs is adapted to extract and enhance adsorption of a different type of biological molecule from the other solutions housed in the other reservoirs; a valve coupled to the plurality of reservoirs via tubing; an injection port coupled to the valve and configured to receive the sample; a reaction mixing tube coupled to the valve and configured to receive the sample and a selected solution from one reservoir of the plurality of reservoirs; and a processor programmed to automatically select which of the solutions from the plurality of reservoirs should contact with the sample based at least in part on the type of biological molecule to be isolated, to control the valve to cause the selected solution and the sample to flow to the reaction mixing tube for mixing, and to control the valve to cause a mixture of the selected solution and the sample to be diverted from the reaction mixing tube to the substrate.
