Detection of microplastics in a digested complex organic medium by Raman Tweezers
AI summary Read the abstract
Researchers used Raman tweezers to optically trap and identify individual polystyrene microbeads within a complex biological medium produced by digesting mussels. This technique shows that optical trapping can detect microplastics in challenging biological matrices relevant to food safety monitoring.
Raman Tweezers (RT) were exploited to trap and characterize polystyrene microbeads floating within a complex medium obtained by the digestion of a mussel which is considered a bioindicator for microplastics pollution.
