Abstract:

Biomotors are involved in countless vital active processes including muscle motion, heart beating, lung breathing, DNA replication, cell division and viral DNA packaging. When I was a graduate student, I discovered an RNA molecule that drives the viral DNA packaging motor. Subsequently, I constructed the active viral DNA packaging motor in vitro from purified components. During my faculty career, I focused on the study of this RNA-geared biomotor. Our research has led to three major advances: 1) Discovery of a third type of biomotor by revolving mechanism without rotation; 2) Insertion of the motor channel into membrane to serve as a robust nanopore for single molecular sensing; and 3) promotion of the emergence of a new field of RNA nanotechnology.  I will present the translation of these three findings into industrial and biomedical application including single molecule detection and sensing single pore for high throughput DNA sequencing, potent drug development, organ imaging by fluorescence and radioactive isotopes, therapy and diagnosis of cancer and other diseases, as well as other applications in material science, biocomputer modules, and nanomedicine.
