要約(日本語): We present a facile method for preparation of nanoporous gold films using a simple wet chemical method. Suspended droplets of the mixture contained tetrachloroauric (III) acid and sodium formate were deposited on the surfaces of cylindrical PDMS disk. The fabricated nanoporous gold films on the PDMS disk exhibited superhydrophobic property with the water contact angle as large as 167°. Systematic characterization revealed that Marangoni flows involves in the formation of the nanoporous superhydrophobic gold films. The fabricated nanoporous gold films were employed as high performance SERs substrates which could provide clear characteristic SERS spectrum of 10-7 M R6G.
