SEEDING to Enable Sensitive Electrochemical Detection of Biomarkers in Undiluted Biological Samples (Adv. Mater. 24/2022)

Electrochemical Pollination In article number 2200981, Yoon‐Kyoung Cho and co‐workers discuss electrochemical roughening, a method based on the etching and redeposition of material from a flat surface, to create homogeneous, nanostructured, and nanoporous gold electrodes. The process is not efficient, as most of the etched material typically diffuses away. However, the addition of surfactant generates micelles that can electrostatically capture the freshly etched material and, in a process that evokes pollination from bumblebees, increase redeposition efficiency.
