In this paper, we will demonstrate a selective surface patterning method by a micro-plasma discharge. In this method, argon plasma is ignited through a hole of copper clad polyimide microstructure electrodes. As an illustration, experiments were performed in which an octadecanethiol (CH3(CH2)17SH) self-assembled monolayer (SAM) on a gold film is exposed to a microdischarge and subsequently followed by immersion into the 16-mercaptohexadecanoic acid (COOH(CH2)15SH) solution. The octadecanethiol SAM is desorbed upon Ar plasma exposure, allowing the formation of a second SAM on the damaged region [Chai et al, App. Phys. Lett., 86, 034107 (2005)]. The patterned samples are viewed by using optical microscope and scanning electron microscopy. The advantage of this approach is that it is noncontact and eliminates the need of photolithography. The patterned samples can be employed to microfluidic self-propelled movement.

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.
