Hyalin-derivatized microbeads could be used in the purification.
Each signature sequence is cloned onto one of a million microbeads.
Microbeads accounted for 90 percent of these plastics.
Microbeads are designed to be small enough to wash down the drain, but they are not caught by sewage treatment, instead flowing into waterways.
The microbeads are then arrayed in a flow cell for sequencing and quantification.
Plastic microbeads used in cosmetic exfoliating products are also found in water.
Fluorescent microbeads lodged throughout the tissue, providing discrete coordinates that aided in computerized calculations of strain and deformation.
The coating of the microbeads contains also ligands to be able to attach the molecules of interest.
