Graphene has emerged as the most popular subject area in the active research field since its discovery in 2004. The published documents illustrate the popularity of Graphene research and innovations, spontaneously increased from about 150 in 2004 to 21,500 in 2018. Graphene is relatively young but high-hope for markets. The cover photo of May 2019 issue describes the structure of a cylindrical Graphene to celebrate the 15th anniversary of it's discovery.

In this article, we introduce the innovative nanotechnological approach of remote electric stimulation mediated by ultrasound-sensitive piezoelectric nanoparticles, especially focusing on its exploitation in the nanomedicine field for the “wireless” anticancer electric treatment. The nanoparticle functionalization with specific ligands allows the targeting, imaging, and ultimately the treatment of cancer cells. Piezoelectric stimulation can be performed in remote modality with ultrasound waves by virtue of the direct piezoelectric effect. Chronic piezo-stimulation is able to remarkably decrease cancer cell growth by inducing the cell cycle arrest in G0/G1phase and by affecting the cytoskeleton organization during cell division. The reported results indicate an impressive potential impact of this nanotechnological approach, that will be further tested in future works in synergic combination with chemotherapy treatment.
