Applications of Nanotechnology: Imaging, Detection and Nanoelectronics

Mihri OzkanAssociate Professor at the Department of Electrical Engineering
Center for Nanoscale Science and Engineering
University of California Riverside Importance of engineering at the nanoscale is more appreciated recently to cure diseases such as cancer or to fabricate devices at the scales off bacteria or virus with improved performance. In my talk, I will be giving number of examples from our recent studies specifically about imaging of nanotherapeutics, DNA sensors and bio-templated electronic devices such as resonant tunneling diode and memory. Firstly, label-free detection of nanoparticle therapeutics for in-vitro applications on human breast cancer cells will be demonstrated using a custom built hybrid AFM/NSOM platform. Different types of operational modes revealed the special placement of iron oxide nanoparticles on breast cancer cells after incubation at varying conditions. This study demonstrated label-free imaging of iron oxide particles and their uptake percentage based on their size and time of incubation. Secondly, multi-segmented nanowires in electrical sensor platform will be introduced with successful demonstrations of presence/absence of complementary DNA sequences inside the test buffer. Lastly, nanodevices synthesized using different bio-templates including DNA, PNA and viruses will be introduced. Electrical characterization of hybrid memory and negative differential resistance will be discussed on quantum dot/virus and SWNT/DNA or PNA hybrids, respectively.
