Seminar Abstract:
The success of medical nanotechnology in response to the recent COVID-19 pandemic has boosted development of nanomaterials for broad diagnostic and therapeutic use. Their size-dependent properties allow us to spy on cellular machinery without introducing much interference. To interact with complex biological systems, engineered nanomaterials require information-rich and autonomous attributes which rely on precise molecular design and engineering of both organization in three-dimensional space, and physicochemical properties imparted by assembled structure. This talk presents engineering efforts of nanomaterials comprise sequence-defined biomolecules to generate high-performing structures at multi-scales and how they can be applied to understand biological processing and nanomedicine. First, I will focus on engineering DNA constructs to organize proteins and nanoparticles into precise and programmable architectures. This part revolves around designs at the interface of molecular and nanoscale objects that impact assembly and reconfiguration behaviors. Next, I will discuss the critical role of peptide molecular designs for an understanding of sequence-structure relationships of disease-associated, plaque-forming amyloid proteins. Further, by integrating with in vivo nanosensor designs, I will show that engineered peptides can act as multiplexed synthetic biomarkers to reveal aberrant activities in the disease microenvironments and for non-invasive diagnostics of lung cancer.

Dr. Shih-Ting (Christine) Wang’s Bio:
Dr. Shih-Ting (Christine) Wang is postdoctoral associate in the lab of Dr. Sangeeta Bhatia in the Koch Institute and fellow of the Ludwig Cancer Center at the Massachusetts Institute of Technology. Her current project focuses on the development of in vivo activity-based nanosensors for non-invasive detection of lung cancer and infection. Prior to this, she was a research associate in the lab of Dr. Oleg Gang at Brookhaven National Laboratory, where she worked on DNA nanotechnology for protein lattice engineering and nanomedicine applications. Wang completed her Ph.D. research in the lab of Dr. Molly Stevens on type II diabetes-related biosensing and amyloid fibrillation. From 2016 to 2020, she has been a facility user and collaborated on multiple research projects with the Molecular Foundry at Lawrence Berkeley National Laboratory.
