Research Interests

Research in the��Biomolecular Materials and Nanoscale Assembly Lab��is focused on the design and use of chemistry, biology and chemical engineering to synthesize and create well-defined organic-inorganic systems from nanoscale building blocks. Because biological molecules, such as peptides, DNA, and proteins, provide significant capabilities for the assembly of nanoscale materials, a significant portion of the research centers at developing bio-nano interfaces and using biomolecular interactions for the assembly. Specific applications include engineering novel protein nanosensors for��in vitro��and��in vivo��detection, using DNA for nanoparticle thin film device fabrication and developing novel bio-inorganic interfaces for catalysis.
