Research in the Knecht Group focuses on the use of biological macromolecules to construct nanomaterials for specifically targeted applications. These applications include catalysis, self-assembly, detection, and materials design. We use a wide variety of biological, chemical, and material synthetic strategies to design and engineer specific functionalities into our materials that can be exploited for desired processes. The ultimate goal of our research is to understand the relationship between the material and its function through structure-function analyses.
