- •
A microcantilever sensor in stress mode was developed to detect aflatoxin B1 (AFB1).
- •
The detection limit of nanomechanical sensor for AFB1 is as low as 0.03 ng/mL.
- •
The sensor could quantify the AFB1 in label-free manner.
- •
The sensitivity was increased greatly compared with microcantilever in dynamic mode.
