The aim of the "MCED-Implant" project is to develop a module for structured electrochemical metal deposition from an electrolyte drop with a volume of just a few nanoliters (Meniscus Confined Electrochemical Deposition, MCED). To this end, based on a device platform (nanoplotter) developed by project partner GeSiM, an electrolyte drop is moved over a conductive surface (e.g., wafer) and a continuous electrolyte flow is achieved. At the same time, an electric field is applied between the surface (cathode) and the module (anode) using a potentiostat in order to deposit metallic structures from the electrolyte drop. 

After experimental selection and optimization of the electrolyte composition for the deposition of copper and gold structures, which also includes electroanalytical methods such as cyclovoltammetry (CV) and rotating disk electrode (RDE), the execution and control of the module are developed and optimized in close cooperation with the project partner through MCED experiments. The quality of the deposited microstructures is characterized by various measurement methods (4-point method, optical microscope, profilometer, SEM, etc.). 

The MCED process is combined with the additive manufacturing technology for bioimplants and biosensors developed by GeSiM over many years.
