79% of all plastic that has ever been made is still in landfills or the natural environment, breaking down into tiny toxins - nanoplastics. To address nanoplastics, #OpticaFoundation Challenge recipient Justus Ndukaife, vanderbiltu, is using the prize to create a high throughput method to trap and analyze nanoscopic plastic particles. With plasmonic nanotweezers, Ndukaife's method is paving the way for a quicker, more accurate way to study environmental contaminants. #Environment #Photonics
