Federal University of São Paulo, Brazil, DOI: https://doi.org/10.1016/j.cca.2022.04.235

The electrode material was particularly important in this study. Carbon electrodes allow a very wide potential window to be used while avoiding oxidation of the electrode itself.

Martin Perez Estebanez,

Universitiy of Burgos, Spain, DOI: https://doi.org/10.1016/j.bioelechem.2024.108814

Using a single-use screen printed carbon electrode modified with poly(amidoamine) PAMAM dendrimer, an impedimetric biosensor was created for the sensitive and specific detection of miRNA-34a. A biomarker for important illnesses including Alzheimer's and several malignancies.

K. Arzum Erdem Gürsan,

Ege University, Turkey, DOI: https://doi.org/10.1016/j.microc.2019.05.040

The screen-printed carbon electrode was key to transitioning environmental electro-remediation to a decentralized setting.
