In this work, we demonstrate the implementation of a recently developed electrochemical real-time polymerase chain reaction technique on a silicon microchip for simultaneous DNA amplification and detection. The real-time DNA amplification relies on an electroactive DNA intercalator, methylene blue (MB), for electrochemical signal measurements. Compared to other existing electrochemical methods for...
In this research, we combined the electrochemical etching (ECE) and the metal-assisted chemical etching (MACE) to develop a composite vertical etching process for silicon material and then discuss the etching results influenced by experimental parameters. The experimental results show that the developed composite etching process has faster etching rate than both electrochemical etching and metal-assisted...
In this study we presents an effective and simple process for forming multi-level vertical structures on a (100) silicon wafer. The dual materials including gold and platinum was employed as catalytic material in the etching process. We employed an etchant solution consisting of 4.6 M hydrofluoric acid, 0.44 M hydrogen peroxide, and isopropyl alcohol to produce microstructures at an etching rate of...
