[Abstract]
Matured synthesis of inorganic nanocolloids today have allowed production of diverse asymmetric nanoparticles (NP) and even more complex assemblies, introducing a variety of nanomaterials with unique properties. In many cases, the symmetry of the nanomaterials plays a crucial role in determining the electronic structure, optical activity, and physical dynamics of the system. Full control of rendering assembly pathways primarily dependent on nanoparticle symmetry can allow us to design new functional materials and open enormous opportunities in renewable energy, health care, environmental monitoring, and beyond. However, precise symmetry assignment and regulating the symmetry breaking factors to nanoscale materials is a challenging task due to their multicomponent nature and multiscale dynamics. Several important examples and approach to overcome these challenges will be discussed in this talk. The first part will highlight some initiatives and efforts to discover symmetry breaking factors of optical NPs that showed a new pathway to understand previously puzzling phenomena of seemingly symmetric system or to build complex superstructures with lowest symmetry, chirality. The second part will be focused on practical application of chiral nanomaterials in extended fields - photonic and biomedical applications to overcome the current limitation of (bio)analytical chemistry and establish a new paradigm of biomedicine.
