Time: 11am-12pm

Abstract

This talk will first present an overview of our work in carbon-based nanosciences. I will first present our group’s earlier work of carbon-based nanomaterials including carbon nanotubes and graphene nanoribbons, including synthesis, investigation of electrical and optical properties and applications in the renewable energy field. I will then present our work on in vivo fluorescence biological imaging in the 1000-3000 nm NIR-II/short-wave infrared (SWIR) window to benefit from suppressed light scattering at long wavelengths. I will show in vivo NIR-II imaging with millimeter tissue depth, single-cell spatial resolution, and real-time temporal resolution using a wide range of nano-scale fluorescent/luminescent nanoprobes emitting > 1000 nm including carbon nanotubes, quantum dots, rare-earth down-conversion nanoparticles, and donor-acceptor organic molecules. Our latest work on non-invasive one-photon in vivo imaging of single immune cells in mouse lymph nodes under 1650 nm excitation in the 1700-2000 nm emission range will be presented.

Bio

Hongjie Dai is the Jackson-Wood Professor of Chemistry at Stanford University. He has made fundamental contributions to nanosciences especially to novel carbon-based nanomaterials including carbon nanotubes and graphene nanoribbons. He pioneered nano-carbon biological and nanomedicine applications including imaging in the NIR-II/SWIR window. In the renewable energy area, he advanced new electrocatalysts for splitting fresh water and sea-water, and developed rechargeable aluminum-ion battery and Na/Cl2 and Li/Cl2 batteries.

Dai is a member of the US National Academy of Sciences, National Academy of Medicine, a fellow of the American Academy of Arts and Sciences and a foreign member of the Chinese Academy of Sciences. Dai received the APS James McGroddy Prize for New Materials, the ACS Pure Chemistry Award, the MRS Mid-Career Researcher Award, the NIH Director’s Pioneer Award, the Humboldt Research Award, and others.
