ABSTRACT

The combination of genetics, photonics, electronics and micromechanics is producing completely new micro- and nano-technological approaches for compact and effective tools for diagnostics and therapeutics, which can be disposable, wearable, implantable or tattooable. These new approaches are opening the way to closed loop theranostics, i.e. device integrating diagnostic capabilities and therapeutic response. In this context, the center for biomolecular nanotecnologies (CBN) is exploiting nanophotonic, nanoelectronic and micromechanical technological approaches to produce innovative in-vivo implantable/wearable devices and invitro assays. Recent results on implantable probes and optrodes for optogenetics, on piezoelectric microelectromechanical systems (MEMS) for wearable sensing and for energy harvesting from the human body will be presented and discussed.

Assistant Professor, Neuroscience
Baylor College of Medicine

Time: 10:30 am
Place: 414 CEPSR
Host: Michal Lipson

 

ABSTRACT

Technological advances in nanoscale materials and devices is allowing us to manipulate and measure brain activity with unprecedented precision. These new neurotechnologies thus open the door to a deeper understanding of the brain and improved methods to treat brain
disorders. In this talk, I will discuss how nanotechnologies for probing the brain of small
invertebrates (C. elegans and Hydra) may inform the development of high-bandwidth human
brain interfaces. I will then discuss how we might realize these high-bandwidth interfaces with
flat implantable microscopes and magnetically activated materials. Together these advances in
nano-neurotechnologies provide a path to better understand the brain and manipulate its
activity to treat disease.

MRSEC Seminar: Metal-Organic Magnets Incorporating Redox-Active Semiquinoid Ligands: From Molecules to Materials

Prof. David T. Harris
Department of Chemistry
Northwestern University

Date: Tuesday, November 1, 2016
Time: 4:00 pm
Place: 750 CEPSR
Host: Xavier Roy

 

ABSTRACT

Molecule-based metal-organic magnets offer several key advantages over their inorganic counterparts, such as chemical control and tunability of structure and function, solution-based synthesis and processability, and low density. These compounds may find use in applications including spin-based information storage and processing, the development of lightweight permanent magnets, and the magnetic separation of gases. All of these applications would benefit from a higher operational temperature, which is directly correlated to the strength of magnetic interactions within the compound. This presentation will describe our efforts to synthesize metal semiquinoid molecules and extended solids that feature strong magnetic exchange coupling between metal and ligand radicals. More specifically, it will present the synthesis and properties of new radical-bridged compounds comprising dinuclear molecular complexes, one-dimensional chain compounds, and two-dimensional layered materials. In addition to magnetic properties, electronic conductivity and optical properties of these compounds will be presented.

MRSEC Seminar: Excitons, Disorder, and Nonequilibrium Transport in Semiconductor Nanomaterials

Prof. William A. Tisdale
Department of Chemical Engineering
Massachusetts Institute of Technology

Date: Tuesday, October 18, 2016
Time: 4:00 pm
Place: 750 CEPSR
Host: Xiaoyang Zhu
 

ABSTRACT

In nanostructured materials, the short length and time scales over which energy moves can present transport behavior that deviates from classical constitutive laws. Using a combination of ultrafast spectroscopy, time-resolved optical microscopy, and kinetic Monte Carlo simulation, I will show how these effects manifest in assemblies of colloidal quantum dots (QD) and atomically thin 2D semiconductors, which are promising components of next-generation photovoltaic and lighting technologies. In particular, we will explore the effect of structural and energetic disorder, the role of nanocrystal surface chemistry, and the self-organization of these nanomaterials into ordered superstructures.
