Nature carries out biochemical reactions with exquisite selectivity and efficiency often employing metal ions, metal cofactors and metal clusters organized in predefined architectures. Learning from nature the Chakraborty group aims to combine inorganic/materials (metals, organometallic cofactors, and metal clusters) and bionano components (proteins, peptides, and DNA) to design artificial entities with novel functionalities and architectures unprecedented in nature. Such hybrid systems will have promising solutions to many global challenges such as energy and healthcare. Within this broad scope we are trying to gain fundamental understanding and explore their applications in the following research areas: 1) bioinorganic chemistry-designing novel metalloenzymes, 2) designing novel metallopeptides for Alzheimer’s disease and 3) exploring the role of gold nanoclusters in energy and catalysis.
