Electrochemical Atomic-Force Microscopy Using a Tip-Attached Redox Mediator. Proof-of-Concept and Perspectives for Functional Probing of Nanosystems

Autor: Agnès Anne, Cédric Goyer, Christophe Demaille

Publikováno v: ACS Nano. 3:819-827

This paper presents the first steps toward the development of a new type of high-resolution AFM-SECM microscopy which relies on the use of tip-attached redox-labeled polymer chains as mediators to probe the local electrochemical reactivity of a plana
