Graphene-coated nanoprobe — New approach to obtain conductive probes with enhanced reliability and lifetime

Nanoprobes are highly required in many fields of science, including physics, mechanics, microelectronics, nanotechnology, medicine and biology, as they allow fabrication and characterization with high spatial resolution. But, unfortunately, most nanoprobes available in the market lose their initial good performance extremely fast after some scans or spectroscopic measurements, especially during electrical or mechanical experiments. This webinar will introduce the use of high-quality solution-processed (and spray-coating) graphene sheets to enhance the performance of ultra-sharp nanoprobes. The results prove that graphene-coated nanoprobes not only ensure obtaining high-resolution images, but also enhance the reliability and lifetime. The simplicity and low cost of this method, which can be used to coat any kind of sharp tip, make it suitable for the industry, allowing production on demand. Moreover, the selection of conductive probes referring to the experimental requirements will also be introduced.
