Iron Single‐Atom Catalysts on MXenes for Ultrasensitive Monitoring of Adrenal Tumor Markers and Cellular Dopamine (Adv. Mater. Technol. 6/2023)

Single Atom Catalysts In article number 2202069, Saptami S. Shetty and co-workers present the synthesis of an electrocatalyst, iron single-atom catalysts (Fe-SACs) on Mxene sheets, and developed an ultrasensitive electrochemical sensor for adrenal tumor markers. The sensor was validated in human samples including urine, serum, and PC12 cells. This study shows that Fe-SACs/MXene-based materials hold the potential for diagnosing adrenal medulla malignancies.
