• -supported gold nanoparticles (Au/C) have been extensively studied for their remarkable selective catalytic performance in low-temperature oxidation reactions, including CO oxidation, alcohol oxidation, hydrocarbon oxidation, amino and thiol oxidation, and glucose oxidation [20]. However, despite their

• formation of the gold nanoparticle-conjugated structures is facilitated by (i) the collectively higher dielectrophoretic response of the origami-supported gold nanoparticles, and (ii) the generation of local fields of higher intensity and steeper gradient around them. The first effect is related to the
