Gold nanocaps were prepared by vacuum depositing gold films onto self-assembled monolayers of SiO2nanoparticles, and characterized using SEM, AFM and XRD. Its antibacterial activity was investigated. It was found that gold films with cubic structure have completely covered self-assembled monolayers of SiO2nanoparticles. The gold nanocap, comprising of 20 nm gold film and 450 nm SiO2nanoparticles, possesses high antibacterial activity.

Duplex Formation

Self-assembled monolayers of sulfur-terminated oligonucleotide duplexes were formed on flat gold surfaces, either by exposure of a self-assembled monolayer bearing one oligonucleotide strand to the complementary strand or by preformation of a oligonucleotide duplex that was then deposited on a fresh gold surface. Virtually identical spectral behavior was observed whether the duplex was produced before deposition or by in situ complementary association. With a duplex bearing an appropriate pyrene end-label, the resulting thin film was photoresponsive. Surface emission measurements show no evidence for pyrene aggregation on the modified surfaces. The polarity of the photocurrent, reflecting photoinduced electron transfer initiated by photoexcitation of pyrene, is opposite that expected from the oligonucleotide-mediated reduction of the appended pyrene excited state.Key words: oligonucleotide, self-assembled monolayer, duplex formation, photoelectrochemistry, surface emission.
