24 Apr 2020 --- Finland-based research facility VTT is developing a method that uses nanocellulose structures for the early identification of microplastic particles before they enter waterways. Microplastics are just 100 nanometers in diameter – the width of a human hair. Moreover, the nanocellulose structures may prove instrumental in determining the concentration of microplastics in water as well as in analyzing how many particles are released into drinking water from plastic bottles.
