a) Schematic of spin-valve device architectures composed of self-assembled monolayers (SAMs) of 11-amino-1-undecanethiol (AUT) and electrostatically adsorbed films of bovine serum albumin (BSA) or thermally denatured bovine serum albumin (dBSA) sandwiched between non-ferromagnetic Au and ferromagnetic Ni electrodes. An external magnetic field is used to magnetize the Ni electrodes parallel or antiparallel to the normal axis of the devices. b) Average current-voltage measurements for Au/BSA/Ni (solid circles), Au/dBSA/Ni (solid triangles), and Au/BSA/Au (open circles) junctions from three substrates (photograph in inset). Shaded areas represent standard error of the mean from N=3 substrates for each condition (n=60 panels tested per magnetic field orientation per substrate).
