Nanotechnology is the manipulation of matter with at least one dimension sized from 1 to 100 nanometers (nm). In recent times, it has constantly revolutionized different sectors, moving from materials science to medicine, as a promising tool with unparalleled features different from bulk materials. Manipulating materials at these dimensions is challenging and astonishing due to the possibility of exploring new properties and to creating materials with innovative features for a variety of uses. Due to these features, they are widely used in biomedical applications such as drug delivery, biosensors, nanomedicines, bioimaging and gene therapy, but also in the industrial sector especially in the wastewater treatment, packaging materials, automotive, just to name a few.
