Using strands of DNA from the sperm of salmon are extracted, researchers from Tianjin University dissolved the genetic matter in water with ionomers, a type of polymer commonly found in adhesives, to produce a gel that’s pliable enough to be moulded into various forms.
The material is then freeze-dried to set the shape, The Times reported.
The experiment led to the creation of a rumpled-looking mug, as well as puzzle pieces, all made of what they call “DNA-based plastic”.
Both DNA and plastics are made of polymers, which may be naturally occurring or synthetic — the former abundantly available in plants, animals and bacteria, and the latter relying on petroleum oil or fossil fuels.
A new study published in the Journal of the American Chemical Society found that the result looks and feels somewhat like plastic but produces less than 5 per cent of the carbon emissions generated during typical polystyrene plastic manufacturing.
Lead researcher Dayong Yang said to their knowledge, DNA plastics are the most environmentally sustainable materials of any known plastics.
......
Other useful applications for the substance include electronics and other forms of packaging.
Their research comes as scientists scramble to find solutions to reduce plastic waste.
