Self-assembled monolayer (SAM) films of p-aminophenyl trimethoxysilane (APhTS) and 3-mercaptopropyl trimethoxysilane (MPTS) were used to immobilize gold nanoparticles (AuNPs) on silicon substrates and silicon-based microdevices, which created robust

Evidence suggests that in order for a surface to support an extensive water structure, it must possess sufficient Lewis cites so that water-surface interactions are favored over water-water interactions. In this paper we use ATR-FTIR to comparatively

Digital Phase Shifting Interferometry (PSI) is widely used in optical testing to determine the surface topography of a continuous surface. The height pro??le obtained using PSI is derived from intensity measurements made at different phases, which ar

Digital phase-shifting interferometry (PSI), a technique widely used in optical testing, requires interferograms collected at optical phase differences separated by a definite phase step. The five-frame interferogram-collecting sequence suggested by

In order to alleviate or eliminate the occurrence of stiction during the actuation of microstructures, the real contact area available for contact must be reduced. Au nanoparticles were intentionally deposited using gas-expanded liquids onto polysili
