selectivity curve under dynamic condition. The presence of
oxLDL (15.1%) gave rise to the highest conductivity compared with nLDL (4.4%).
HPLC chromatograms of LDL were used to validate the results. Three peaks are
seen, starting with the most abundant native LDL (nLDL), followed by the
oxidized LDL. The top left insert shows the electrodes of source and drain in
relation to the nanowires.
