This paper describes synthesis of ultrathin pinhole-free insulating aluminum oxide layers for electronic device protection in corrosive liquid environments, such as phosphate buffered saline (PBS) or clinical fluids, to enable emerging biomedical applications such as biomolecular sensors. A pinhole-free 25-nm thick amorphous aluminum oxide layer has been achieved using ultra-high vacuum DC magn...

Surface chemistry studies of the chemical mechanical planarization ~CMP! of copper are presented in this paper. Blanket copper samples were polished with an acidic alumina-based slurry which contains an organic acid salt ~phthalic acid salt! and an oxidizer (H2O2!. Surface studies using X-ray photoelectron spectroscopy ~XPS! were performed on copper samples after chemical etching or CMP in orde...

Surface plasmon resonance sensors (SPR) using copper for sensitive parts are a competitive alternative to gold and silver. Copper oxide is semiconductor has non-toxic nature. The unavoidable presence of may be interest as it non-toxic, but modifies the condition performance sensor. Therefore, characterization optical properties thin films interest. We propose method recover both thicknesses fro...

Copper has two key properties that are being exploited in consumer and medical device products in the last decade. On the one hand, copper has potent biocidal properties. On the other hand, copper is involved in numerous physiological and metabolic processes critical for the appropriate functioning of almost all tissues in the human body. In the skin, copper is involved in the synthesis and sta...

Well-crystallized flower-shaped copper oxide nanostructures composed of thin leaves have been synthesized by simple low-temperature chemical bath method and used to fabricate pH sensors. We examined the effect of the pH on the growth of the CuO nanostructures. By changing the pH of the precursor solution different morphologies of the CuO nanostructures were obtained. CuO nanoflowers have recent...
