White gold films (Au 35 Ag 65 in at.%) of 100 nm thick were used in this study. The NPG films with different pore sizes were prepared by five processes, e.g. PED, LT-CD, RT-CD, LC-CD, and SA-CD. The PED was carried out using a square-wave voltage of 0.6 V with a successive cycle of 50 ms on-time and 10 ms off-time.The two-electrode …

The factors investigated were the concentration of the GO dispersion, etching time, and the thickness of the gold film. The GO concentration was varied to investigate its effect on the pore density and on the pore spatial distribution. Four concentrations were used, 2, 4, 6 and 8 mg/mL and the etching time was set to 15 s. ...

To circumvent this, we proposed here the use of a readily shrink-induced, wrinkled Au-coating polyolefin film to immobilize a greater number of DNA probes and thus improve the signaling. Specifically, wrinkled gold film exhibits a 5.5-fold increase of surface area in comparison to the unwrinkled ones.
