  • Hongjie Dai

    Hongjie Dai

    The J.G. Jackson and C.J. Wood Professor in Chemistry

    BioProfessor Dai’s research spans chemistry, physics, and materials and biomedical sciences, leading to materials with properties useful in electronics, energy storage and biomedicine. Recent developments include near-infrared-II fluorescence imaging, ultra-sensitive diagnostic assays, a fast-charging aluminum battery and inexpensive electrocatalysts that split water into oxygen and hydrogen fuels.

    Born in 1966 in Shaoyang, China, Hongjie Dai began his formal studies in physics at Tsinghua U. in Beijing (B.S. 1989) and applied sciences at Columbia U. (M.S. 1991). His doctoral work under Dr. Charles Lieber at Harvard U. (Ph.D. 1994) focused on charge-density waves and superconductivity. During postdoctoral research at Rice U. with Dr. Richard Smalley, he developed carbon nanotube probes for atomic force microscopy. He joined the Stanford faculty in 1997, and in 2007 was named Jackson–Wood Professor of Chemistry. Among many awards, he has been recognized with the ACS Pure Chemistry Award, APS McGroddy Prize for New Materials, Julius Springer Prize for Applied Physics and Materials Research Society Mid-Career Award. He has been elected to the American Academy of Arts and Sciences, AAAS and National Academy of Sciences.

    The Dai Laboratory has advanced the synthesis and basic understanding of carbon nanomaterials and applications in nanoelectronics, nanomedicine, energy storage and electrocatalysis.

    Nanomaterials
    The Dai Lab pioneered some of the now-widespread uses of chemical vapor deposition for carbon nanotube (CNT) growth, including vertically aligned nanotubes and patterned growth of single-walled CNTs on wafer substrates, facilitating fundamental studies of their intrinsic properties. The group developed the synthesis of graphene nanoribbons, and of nanocrystals and nanoparticles on CNTs and graphene with controlled degrees of oxidation, producing a class of strongly coupled hybrid materials with advanced properties for electrochemistry, electrocatalysis and photocatalysis. The lab’s synthesis of a novel plasmonic gold film has enhanced near-infrared fluorescence up to 100-fold, enabling ultra-sensitive assays of disease biomarkers.

    Nanoscale Physics and Electronics
    High quality nanotubes from his group’s synthesis are widely used to investigate the electrical, mechanical, optical, electro-mechanical and thermal properties of quasi-one-dimensional systems. Lab members have studied ballistic electron transport in nanotubes and demonstrated nanotube-based nanosensors, Pd ohmic contacts and ballistic field effect transistors with integrated high-kappa dielectrics.

    Nanomedicine and NIR-II Imaging
    Advancing biological research with CNTs and nano-graphene, group members have developed π–π stacking non-covalent functionalization chemistry, molecular cellular delivery (drugs, proteins and siRNA), in vivo anti-cancer drug delivery and in vivo photothermal ablation of cancer. Using nanotubes as novel contrast agents, lab collaborations have developed in vitro and in vivo Raman, photoacoustic and fluorescence imaging. Lab members have exploited the physics of reduced light scattering in the near-infrared-II (1000-1700nm) window and pioneered NIR-II fluorescence imaging to increase tissue penetration depth in vivo. Video-rate NIR-II imaging can measure blood flow in single vessels in real time. The lab has developed novel NIR-II fluorescence agents, including CNTs, quantum dots, conjugated polymers and small organic dyes with promise for clinical translation.

    Electrocatalysis and Batteries
    The Dai group’s nanocarbon–inorganic particle hybrid materials have opened new directions in energy research. Advances include electrocatalysts for oxygen reduction and water splitting catalysts including NiFe layered-double-hydroxide for oxygen evolution. Recently, the group also demonstrated an aluminum ion battery with graphite cathodes and ionic liquid electrolytes, a substantial breakthrough in battery science.

    Professor of Radiology (General Radiology) and, by courtesy, of Pediatrics (Hematology/Oncology)

    Current Research and Scholarly InterestsAs a physician-scientist involved in the care of pediatric patients and developing novel pediatric molecular imaging technologies, my goal is to link the fields of nanotechnology and medical imaging towards more efficient diagnoses and image-guided therapies. Our research team develops novel imaging techniques for improved cancer diagnosis, for image-guided-drug delivery and for in vivo monitoring of cell therapies in children and young adults.

    Current Research and Scholarly InterestsMy research examines genetic influences on smoking with an emphasis on pharmacogenetics and pharmacogenomics. Current work is translating pharmacogenetic results from clinical trials for bupropion and nicotine replacement therapy into a new clinical trial of genetically-tailored smoking cessation therapy in primary care and medical education. Genome-wide association data and functional neuroimaging complement this work by identifying new molecular targets to advance the state of the scienc

    Current Research and Scholarly InterestsChildhood cancers can be considered aberrations of normal tissue development. We are interested in understanding childhood cancers through the lens of normal development. Further, individual tumors are composed of heterogeneous cell populations, not all cells being equal in their ability to respond to treatment or to repopulate a tumor. Thus, we take single cell approach to determine populations of clinical relevance.

    Professor of Biochemistry and of Genetics

    Current Research and Scholarly InterestsWe are using Saccharomyces cerevisiae and Human to conduct whole genome analysis projects. The yeast genome sequence has approximately 6,000 genes. We have made a set of haploid and diploid strains (21,000) containing a complete deletion of each gene. In order to facilitate whole genome analysis each deletion is molecularly tagged with a unique 20-mer DNA sequence. This sequence acts as a molecular bar code and makes it easy to identify the presence of each deletion.
