It is possible to obtain an optical response from metasurfaces that exhibit second- order circular dichroism thanks to the recent successes in nanotechnology, opening the way to new functionalities on a spatial scale of few hundred on nms. The second order nonlinear response of this kind of nanostructured materials is an interesting and fascinating issue. The second-order nonlinear response of this kind of nanostructured materials is an interesting, as becomes clear from an overview of second harmonic generation and in particular the nonlinear circular dichroism raised by metasurfaces of different morphologies and material components, realized by means of self-assembling methods. In this review we show as the Second Harmonic Generation Circular Dichroism is very sensitive and useful in the field of nanotechnology characterization.
