A novel method to detect nano-and microplastics in vivo

While plastic debris of any size is harmful to the marine flora and fauna, recent research suggests that the smallest of these plastics, nanoplastics, affect the composition and diversity of our intestinal microbiome and that this can cause damage to our health. A novel optical spectroscopy-based methodology in the VIS-NIR range, capable for differentiating between chemically different micro- and nanoplastics confined within invertebrate intestines. The technology is based on dark-field microscopy, which is capable of visualizing particles smaller than the bright-field optical microscopy resolution limit.
