From Nanoelectronics to Nanophotonics: Toward Integrated Bio-Nanosystems

Wei Zhou, PhD
Assistant Professor Bradley Dept. of Electrical & Computer Engineering Virginia Tech



Abstract:In this talk, Dr. Zhou will discuss innovative concepts and approaches to design, fabricate, and exploit novel nanophotonic and nanoelectronic devices/systems for biomedical applications. Nanowire nanoelectronic field-effect-transistors in 3D arrays can be integrated into 3D macroporous polymeric scaffolds to create synthetic cyborg tissues, in which 3D real-time electric mapping of heart activities with drug responses was demonstrated. Moreover, a bio-inert coating technique was developed to achieve long-term stability of semiconductor nanoelectronic bio-sensors for chronic real-time physiological studies. On the other hand, multiresonant plasmonic nanoresonators and nanoantennas can control light flows and enhance light-mater interactions at multiple different wavelengths, and thus can potentially be used as multifunctional or wavelength-multiplexed optical nanosensors and nanotransducers in biological systems. We investigated a new type of multilayered metal-insulator optical nanocavities that can support multiple localized plasmon resonances with ultra-small mode volumes. The total number of resonance peaks and their resonance wavelengths can be freely and accurately controlled by simple geometric design rules. The innovations discussed in this talk could be inspiring for the development toward integrated nanosystems for applications including implantable flexible bio-integrated Nanosystems, lab-on-a-chip biomedical architectures, and handheld point-of-care diagnostics platforms.
