Discussion

New electrochemical approach quantifies B. anthracis spores with a detection limit of 103 CFU/mL, suggesting a promising field application.

The method achieves a detection limit of 103 CFU/mL for B. anthracis spores, indicating high sensitivity for early detection.
Using thiol-modified electrodes, the electrochemical system allows for effective quantification of the pathogen, emphasizing its accuracy.
This portable method can be easily implemented in field analyzers, broadening application possibilities in public health settings.
Considering its low cost and minimal equipment requirements, this technique presents an alternative to conventional detection methods.

Morawska et al. (2025) studied this question.
