Systems biology has introduced a number of multiscale challenges, which, however, can be tackled by colored Petri nets, but not by traditional approaches like ordinary differential equations or Petri nets. In this paper, after a brief covering of multiscale challenges of systems biology, we report the modeling and analysis capabilities of colored Petri nets, which Snoopy by now offers, and describe how these capabilities are used to address those multiscale challenges. In doing so, we aim to attract more researchers to use the powerful capabilities of colored Petri nets to model and analyze multiscale biological systems.
