Abstract

Metallic multilayered nanowires based on gold and platinum were synthesized by pulsed electrodeposition. The free nanowires were impurity-free, with some fine branch-like shapes and non-uniform final lengths. The in-membrane sizes of the nanowires were up to 25 μm in length, and about 200 nm in diameter. The nanowires were the subject of a pathological DNA immobilization, via specific PCR (Polimerase Chain Reaction) amplification, in order to allow the fluorescence-based detection of the specific DNA sequence.
