Research Focus
 Our research is quite interdisciplinary in nature ranging from noncovalent polymer, responsive soft materials, smart nanomaterials, dynamic combinatorial library. Supramolecular polymer is a current topic of great interest because of its extraordinary properties including high degree of internal order, reversibility, stimuli-responsiveness and promising applications. In order to be able to compete with conventional covalent polymers and/or mimic the function of biopolymers, control over structure/conformation, properties and function of the supramolecular polymer is required. We plan to develop strategy for dynamic control over structure of supramolecular polymer with interesting properties and functions where we will look into various aspects including supramolecular polymerization, pathway complexity, self-repairing capacity, dynamic behavior, far-from-equilibrated assembly, mimicking functionality of biopolymer in man-made supramolecular polymer. In this regard, various stimuli including light, redox, ultrasound, pH will be applied making responsive dynamic materials and supramolecular transformations. Biomolecule based responsive materials will be tested for bio-application through proper biocompatible nano-structurization. We are also interested in dynamic peptide libraries for discovery of nanomaterial binding ligands to expand the opportunities for nanomaterials in areas where they are to be interfaced with biological systems. Here we would like to develop conceptually a new methodology for bio-functionalization of nanomaterials where binding ligands are self-constructive. Students will be exposed to learn techniques ranging from organic synthesis, supramolecular synthesis, physical characterization of various materials through spectroscopic (UV/Vis, Fluorescence, etc.) as well as morphological (AFM, TEM, SEM) studies and functionality studies.
