Projanus is a new process which can modify any conductive micro or nano-object, to an asymmetric and bifunctional micro or nano-object. The induced anisotropy in color, charge density or reflective index could open the way to cheap pixels with high refreshing rate.
Janus particles are used in numerous industries:
The technique, based on bipolar electrochemistry, presents a big use flexibility. It allows a wide range of Janus particles formation, in terms of materials, sizes, forms and nature of the modification.
The process allows formation of Janus particles from 200 microns to 50 nanometers, isotropic or anisotropic, with a controlled form and .
This new production technique for asymmetrical particles allows :
