THE FRONT COVER shows a polystyrene nanoplastics and how they are detected with photo-induced force microscopy infrared spectroscopy. This method overcomes the diffraction limit of infrared light by employing a nano-sized tip as detector. Oxidative degradation and chain scission occurred on the surface of the polystyrene nanoplastics in salt water, as depicted by the carbonyl and aliphatic functionalities. Detecting nano-sized plastic particles is essential for understanding how plastic waste breaks down into smaller particles in the environment.
