Abstract: The present invention provides a system and methods for the detection of peptides from and antibodies against coronaviruses, filoviruses, flaviviruses, or combination thereof, in a sample. A method for detecting the presence of a coronavirus in a sample may comprise: collecting a small sample of a biological fluid from the test subject, adding sample to a viral test cassette, initiating sample processing by the assay cassette to incubate the diluted sample and developing reagents with an antibody microarray contained within the cassette, and results of the test are read by visual examination and process the results to determine if the subject is infected by a coronavirus.

Abstract: Surfaces and methods for producing surfaces for immobilizing biomolecules on a first side and modifying a second side to block non-specific interactions are provided.
