UM Chemistry/INDIUM

INDIUM was established in 2004 to promote development and innovation in the research of nanomaterials. Our mission is to facilitate interdisciplinary research and education in nanoscale science and engineering at the University of Memphis and collaborating institutions and serve as nanotechnology research and education hub for Southwest Tennessee and surrounding areas. INDIUM currently includes faculty members in chemistry, physics, biology, and biomedical engineering.

Focus: Design nanomaterials and nanodevices for biomedical applications. Current research includes the development of fabrication methods based on guided assembly with applications in drug delivery, nanobioreactors, and biosensors. These materials have tremendous potential in novel implantable biodevices. Analytical and fabrication facilities include Integrated Microscopy Center, X-ray diffractometer, nanoindenter, wet laboratories, and access to synchrotron x-ray facilities at national laboratories.
