Chirality has emerged as a unifying concept across materials science, enabling breakthroughs in both energy-efficient electronic systems and precision biomedical platforms. In this seminar, we highlight recent advances in chiral optoelectronic materials and their dual roles in reducing energy consumption and enhancing biofunctionality. Chiral selenium nanorod lattices demonstrate broadband circularly polarized light detection with remarkable stability, providing a foundation for low-power optical sensing. Meanwhile, chiroferromagnetic quantum dots offer enhanced g-factors and optical synaptic behaviors, making them ideal candidates for neuromorphic AI processors that operate on polarization-encoded signals. On the biomedical front, a universal chiral nanopaint strategy has been developed to impart chiroptical functionality to a range of metal oxide nanoparticles, enabling enantioselective interactions critical for targeted drug delivery. Together, these advances suggest a paradigm in which chirality is not merely a structural attribute, but a powerful design tool for integrated systems that span energy and bio. The seminar will discuss how such chiral architectures can be engineered, implemented, and scaled to develop multifunctional devices that bridge the demands of next-generation AI and medicine.
