Summary
Researchers investigated which light wavelengths are best for detecting microplastics using photoluminescence, a technique where particles glow under specific light. Finding the optimal excitation wavelength could make this a practical, low-cost complement to existing microplastic detection tools.
The identification of microplastic particles by photoluminescence could be a low-cost addition to established spectroscopic methods. Here, we investigate which excitation wavelength is optimal for such investigations.
