It was demonstrated that PickMol™ technology enables effective detection of micro- and nano-plastics in water from a variety of sources, including:
- pure laboratory water
- water from grots
- water from natural environments
The micro- and nano-plastics detection methodology is:
-
Simple – no sample pre-treatment required, or only minimal filtration
-
Rapid – analysis completed within minutes
-
On-site – measurements can be performed directly at the sampling location

Most importantly, our calibration curve shows that the signal intensity increases as the plastic particle size decreases. This means that PickMol™ technology performs even better when detecting nano-plastics.
