Designing Gold Nanostar Probes for Optical and Magnetic Resonance Imaging Invited
08:30-09:00
2017-10-02 08:30 2017-10-02 09:00 America/Denver Designing Gold Nanostar Probes for Optical and Magnetic Resonance Imaging This talk will describe how therapeutic gold nanostars can behave as multi-spectral optical probes to interrogate how nanoconstructs interact with cancer cells at the nanoscale and how their shape can significantly boost MRI contrast signals.

Optical trapping assisted enhancement of on-chip single molecule detection rate with a solid-state nanopore
09:00-09:15
2017-10-02 09:00 2017-10-02 09:15 America/Denver Optical trapping assisted enhancement of on-chip single molecule detection rate with a solid-state nanopore A novel optical method for enhancing nanopore-based single molecule detection is demonstrated. Microbeads containing DNA targets are optically trapped under a nanopore to locally increase the concentration. Thermally released DNAs are then detected electrically when moving through the pore at up to 91x higher rates. Hilton Santa Fe Historic Plaza Salon VII

Hyperspectral Expansion Microscopy
09:15-09:30
2017-10-02 09:15 2017-10-02 09:30 America/Denver Hyperspectral Expansion Microscopy We demonstrate high-throughput hyperspectral surface-enhanced Raman scattering based expansion microscopy. NeuN expression in neurons is imaged by antibody conjugated-dye labeled SERS nanoprobes. The technique offers rapid data acquisition, high image contrast, immunity to photobleaching, and abundant information content for potential channel multiplexing.
