SMALL-ANGLE NEUTRON SCATTERING FROM BIO- AND NANO-MATERIALS

Bio- and nano-materials possess a specific shape and charge, which regulate and control their functionality and stability. The particles in aqueous solution are known to interact through different interaction forces. Different phases in any of these systems are preceded and followed by structural changes among them, which can be induced simply by varying temperature or neutralizing the charge on the particle by salt or breaking the water structure by urea. We have used small-angle neutron scattering (SANS) technique for studying the evolution of structure and interaction in different phases of biological and nanomaterial systems. Dr. V.K.
