Soft and Bio Nanomaterials
Soft and Bio Nanomaterials Group at Brookhaven's Center for Functional Nanomaterials
December 5, 2016
Group leader Oleg Gang talks about the methods his group develops to direct the self-assembly of nanoscale systems from organic and inorganic components into functional materials with desired properties.
Novel methods for system fabrication are required in order to build materials and devices that can take advantage of rich variety nanoparticles that are now became available. Approaches based on self-assembly of systems from nano-components might offer tremendous cost advantages and almost a magical ease of manufacturing compared to lithographic methods. Besides, a self-assembly can address tasks that are intrinsically challenging for conventional lithography processes, like, a fabrication of thee dimensional architectures or structures containing pre-fabricated nano-components.
The main goal of the CFN’s Soft and Bio-Nanomaterials Theme is development methods for assembly of hybrid nanoscale systems from organic and inorganic nanoscale components, understanding phenomena driving structure formation and energy-conversion properties of these materials. Our approach for system assembly is based the unique properties of macromolecules, such as the recognition, re-configurability, and reversibility of interactions, which are used to direct and regulated self-assembly of nano-objects into functional materials with optical, electrical, magnetic and bio-sensing functions.
