Abstract :

Translating genome-based knowledge into clinical health benefits is one of the most critical elements for the future nanomedicine. As biology becomes more quantitative, our understanding of the genetic contribution to disease is becoming more refined. However, subpopulations within mixtures of molecules under both equilibrium and non-equilibrium conditions complicate the dissection of complex dynamics of biological processes. To this end, we developed a single particle quantum dot (QD) based biosensing platform, which integrates nanophotonics with microfluidics, for both diagnostics and therapeutics. Single particle biosensing renders better understanding of biophysical properties and dynamics at the single molecules/complex level, allowing heterogeneity in the populations to be directly observed. In this talk, we will evaluate this platform specifically on three aspects: (1) identification of multiple disease-related genes for medical diagnostics, (2) study of delivery barriers for nucleic acids based therapeutics, and (3) characterization and optimization of gene-carrying nanocomplexes. The single particle QD platform, serving as a generic biosensing scheme to investigate a variety of biological entities and their interactions, is expected to advance modern biology by elucidating various biological interactions and to facilitate genetic medicine by contributing fundamentally to therapeutic design.
