Abstract

The interplay between structural chirality and electronic spin, CISS effect, has emerged as a transformative paradigm. This presentation highlights a series of pioneering studies that leverage chiral nanostructures to overcome fundamental limits in energy conversion, storage, and biomedical engineering. We demonstrate how chiral electrocatalysts can manipulate electron spin to suppress the formation of deleterious intermediates, thereby enhancing the efficiency of acidic water electrolysis. Next, the application of chirality extends to Li-O₂ batteries, where it effectively suppresses singlet oxygen generation, leading to dramatically extended cycle lives. The fundamental assembly of hierarchical chiral supramolecules is explored, revealing invertible chiroptical properties with record-breaking dissymmetry factors. We introduce enzyme-like chiral plasmonic nanoparticles for optically tunable cancer therapy, enabling high-precision tumor targeting and minimized side effects.
