Atomic force microscopy was used as a platform for biosensing of L. plantarum, a probiotic microorganism.
A mechanical microbiosensor was developed for detecting active growth of probiotic microorganisms.
Scanning electron microscopy was useful for checking the growth of L. plantarum on the surface of cantilevers.
The analysis of the resonant frequency of microcantilevers functionalized was related to the growth of L. plantarum 299v.
Microbiosensor sensitivity was of the order of 383 pg / Hz.
