Colloquium Series: Nick Stephanopoulos (Arizona State University)
October 22, 2019 @ 4:00 pm - 5:30 pm
Join us for another event in the 2019-2020 Colloquium Series as APS welcomes Nick Stephanopoulos, PhD. to present on his recent research. Dr. Stephanopoulos is currently an Assistant Professor at the Biodesign Center for Molecular Design and Biomimetics at Arizona State University. Stephanopoulos develops self-assembling protein-DNA hybrid molecules as building blocks for complex materials and nano-devices with applications in medicine, biology, and energy. His work seeks to mimic the complexity of biology and is highly interdisciplinary in nature, combining organic chemistry on protein surfaces, self-assembling peptides, DNA nanotechnology and biomaterials engineering.
Presentation Title: “Hybrid self-assembled nanomaterials from proteins, peptides, and DNA”
Abstract: The ability to design materials that mimic the complexity and functionality of biological systems is a long standing goal of nanotechnology, with applications in medicine, energy, and fundamental science. Biological molecules such as proteins, peptides, and DNA possess a rich palette of self-assembly motifs and chemical functional diversity, and are attractive building blocks for the synthesis of such nanomaterials. In this talk, we will describe research in creating hybrid materials that incorporate proteins and peptides with DNA nanotechnology to create cages, nanofibers, and 3D crystals with a high degree of programmability and nanoscale resolution. Key to these endeavors will be (bio)molecular design, organic chemistry for linking components in a site-specific fashion, and the tuning of multiple self-assembly “modes” to create hybrid structures. Although the talk will focus on the fundamental chemistry and self-assembly of these systems, we will also discuss potential applications in areas such as targeted cargo delivery, biomaterials for regenerative medicine, and synthesis of virus- and antibody-mimetic nanostructures.
