Abstract

Scanning electrochemical microscopy (SECM) is a versatile technique, as it allows information to be obtained quickly and with high spatial resolution. One of the most significant benefits of SECM is the exploration of microscopic domains with reduced sample volumes and in cellular environments. However, due to the micrometric dimensions of these environments, the manufacture and handling of these electrodes constitute a challenge for the technique to be fully explored. In this context, the project aims to develop protocols for manufacturing and characterizing electrodes with submicrometric dimensions. These devices will be used as effective electrochemical sensors to detect species of biological interest.
