Designing Functionalized Magnetic Nanostructures for Applications in Microscopy and Imaging Devices Sunkara V Manorama and Lanka Satyanarayana Nanomaterials Laboratory, Inorganic and Physical Chemistry Division CSIR-Indian Institute of Chemical Technology, Hyderabad-500 007. Telangana. India. Email: [email protected] and [email protected], web site: http://www.iictindia.org Materials Science is a fascinating field of science encompassing the design of materials for a wide range of applications. The impact of nanotechnology in materials research demonstrating versatility or multifunction has brought together different disciplines of science and engineering promoting inter/multidisciplinary research. It would showcase our efforts in synthesizing nanosized magnetic metal oxides (ferrites), engineering them by suitably functionalizing them and demonstrating their applications in protein separation, targeted delivery, MRI and also functionalization of the AFM tip with magnetic nanoparticles. Synthesis of well dispersed iron oxide MNPs suitably capped and subsequently biofunctionalised have been successfully demonstrated for application in protein separation and on appropriate engineering and designing, suitable drug molecules could be attached and delivered to the required site. Similarly convenient strategies were developed to make MNPs compatible and suitable as MRI contrast agents. On another front well dispersed ferrite nanoparticles with spinel structure of suitable size, composition and functionality are being tried for attachment to the AFM tip is underway. These are primarily oxides. The composition would be tuned to obtain the desired magnetization, permeability, electrical resistance and suitability for application in magnetic read heads. The present talk would focus on the efforts of our group in the Nanomaterials Laboratory at CSIR-IICT in designing functional nanomaterials focussing on magnetic nanostructures for applications in microscopy and imaging. Findings from the ongoing research activities would be presented.
