Title: Sergio Marras: Innovator in Colloidal Nanocrystals
Introduction
Sergio Marras is a notable inventor based in Campomorone, Italy. He has made significant contributions to the field of nanotechnology, particularly in the area of colloidal nanocrystals. With a total of 2 patents, his work has garnered attention for its innovative approaches and applications.
Latest Patents
Marras's latest patents include a method for patterning colloidal nanocrystal films through a technique known as masked cation exchange lithography. This method combines high energy beam treatment with a cation exchange step, allowing for the selective protection of certain regions of the nanocrystal film. The high energy irradiation cross-links the ligand molecules at the nanocrystal surface, creating a mask for the cation exchange reaction. As a result, the unexposed regions undergo chemical transformation, while the exposed areas remain unchanged. This technique enables the design of patterns formed by chemically distinct nanocrystals within a homogeneous film.
Another significant patent involves the controlled realization of ordered superstructures of octapod-shaped colloidal nanocrystals. These structures can be fabricated either in the liquid phase or on solid substrates, making them applicable in various technological fields.
