Research Topic

DNA dynamics in nanofluidic devices

Recently, many novel nanofluidic devices have been created to manipulate biomolecules for applications such as DNA separation and gene mapping. The origin of the functionality of these devices relies on the confinement-induced change in molecular properties. In this project, we use DNA as model polymer/polyelectrolyte to investigate those confinement effects. The results will provide fundamental understanding of the dynamics of confined molecules as well as the practical guidance for future applications.



 

Single DNA molecule gene mapping

Growing interest in comparative genomics has created a need for technologies that can rapidly characterize a genome. A novel approach is to analyze linearized DNA molecules bound with specially designed, sequence-specific fluorescent tags. The bottleneck of this approach is to effectively stretch(linearize) DNA. We therefore focus on developing a better DNA stretching mechanism that allows more versatile and more stable gene mapping to be performed. The same platform is also expected to be used for investigation of DNA-protein interaction



 

Computer simulations of DNA/polymer behavior in complex flows

We use Brownian dynamics simulations and mesoscale simulations to understand and in some case to predict the DNA/polymer behavior in complex flows and complex geometries. The simulation provides an important means to reveal the underlying physics of observed phenomena as well as a powerful tool to facilitate experimental design.
