The as-prepared biosensor
showed to be selective and highly sensitive for the quantification
of S. agalactiae. This simple approach led to an efficient signal
amplification, greatly reduced the assay steps and incubation
times, and showed great potential to be implemented by untrained
personnel and with minimal requirements for instruments
and reagents. Further efforts will be devoted not only to get a
better electrochemical performance but also to minimize the observed
matrix effects when testing environmental water samples.
