The majority of the debris comprises microplastics that are created by the process
of photodegradation (in the ocean, the sun breaks down the plastics into ever smaller pieces).
Bella et al. show that coating the cells with a water - proof fluorinated polymer that contains pigments to absorb ultraviolet light and re-emit it in the visible range can boost cell efficiency and
limit photodegradation.
The group also found that mNeonGreen works well for GFP's typical applications, from tagging proteins to labelling subcellular compartments, and that the protein is as stable
against photodegradation as GFP.
This happens
through photodegradation and other weathering processes of mismanaged waste such as discarded plastic bags or from unintentional losses such as fishing nets.»
The global scope of the study could help researchers set upper and lower limits for black carbon deposition and better account for the effects
of photodegradation, a process by which sunlight alters the molecular composition over time.
Plastic does not biodegrade and it takes hundreds of years for it to break down through a process of
photodegradation.
