  • Surface Patterning

    gyroid e field

Fabrication of nanostructures and their surface patterning with chemicals and bio-chemicals in the nanometer length has a fundamental importance in nanotech and nanobiotechnology.

The fabrication of nanoporous / nanoparticulate composites and their applications via surface patterning with chemicals and bio-chemicals has a direct impact for the applications in chemistry and biosciences. Surface patterning on particles in suspension can be a complex process due to the aggregation of the particles and their Brownian motion in the suspension. This group is interested on the formation of patterned surfaces and their modification with chemical / biochemical functionalities for highly specific and targeted applications such as bio-sensor, food technology, nanomedicine, magnetic bio-separation, green/ environmental chemistry and industrial catalysis.
