We investigated the impact of surface treatments on Si-based electrolyte-gated transistors (EGTs) for detecting urea. Three types of EGTs were fabricated with distinct gate electrodes (Ag. Au. Pt) using a top-down method. https://www.diegojavierfares.com/super-super-Scratch-Dent-Sandusky-30-Steel-Storage-Cabinet-With-3-Fixed-Shelves-Putty-hot-choice/
