Graphene mixed with a plant creates a bio-inert superparamagnetic material

Researchers from India developed a new superparamagnetic hybrid material made from graphene and the amaranthus dubius plant. This plant is used for food (it's high on protein and contains several vitamins and minerals). Superparamagnetic materials can be used to make very sensitive and accurate sensors.

This new material is biologically inert (as both graphene and the plant are inert) and so this may be useful for applications in biology (such as bio-sensors).
