No one is immune from the effects of ageing.
In order to increase the shelf life of fruit, a research team based in India has developed a reusable wrapper made from graphene oxide.
Molecules on the wrapper are loaded with preservatives, but only released when the fruit is overripe and starts secreting oxalic acid.
This means the fruit avoids contact with the preserving agent until it is necessary, preventing chronic toxicity, which can cause significant health problems.
The carbon used for the graphene in the wrapper is captured during the heating of biomass waste.
As well as keeping fruit edible for longer, the process helps to ensure that food waste is put to good use.
Breaking fresh ground.
