A groundbreaking study demonstrates light-driven inversion of supramolecular chirality, a property critical to pharmaceuticals and materials science. By exposing chiral molecules to specific light wavelengths, researchers reversed their structural handedness without chemicals. This method offers precise control over molecular configurations, enabling tailored drug design and advanced nanomaterials. Potential applications include optoelectronics and biodegradable polymers. The discovery challenges traditional synthesis approaches, paving the way for sustainable, energy-efficient manufacturing processes.
