Abstract

See full text

An atomic level deposition for mass functionalization of a cavity filled with a pathogen sensitive antibody reagent to functionalize each biosensor using atomic level vapor phase deposition enables high volume production of this sensor technology. A biosensor has a first substrate and a second substrate with a cavity formed in the first substrate to form a membrane. Holes are formed through the second substrate. An aluminum oxide layer is formed over the cavity and into the holes to form cores. The cavity is filled with a pathogen sensitive antibody reagent. A biofluid sample with the pathogen is deposited over the membrane. The biofluid is drawn through the cores to mix with the antibody reagent. The antibodies combine with the pathogen to change the impedance along the current path. The presence of the pathogen changes the ionic current flow through the biosensor for a positive detection of the pathogen.
