(a) The current–voltage curves for a gold nanoparticle wire before (solid line) and after (dotted line) exposure to 1-mM Octadecyl Thiol (ODT)/ethanol solution. (b) The conductance changes of a gold nanoparticle wire prepared by a 5-min deposition through continuous addition of 1-μM ODT/ethanol solution. (c) The conductance changes of a gold nanoparticle wire prepared using a 10-min deposition after sequentially adding different concentrations of biotin-bovine serum albumin (b-BSA) protein.^{[ 47 ]}
