Scientists in India have developed a platform to identify the food toxin aflatoxin B1, a fungus found in rice, dried fruits and cocoa beans. The toxin can be carcinogenic. The team’s system involved depositing reduced graphene oxide (RGO) onto indium tin oxide and covalently attaching antibodies for the toxin to the RGO layer. The label-free system displays high sensitivity with a detection limit of 0.12 ngmL-1.
