I was particularly interested in this project as it parallels our HAB mapping design at CSU. The combination of qPCR testing and aerial optical sensing were options we explored in our design but ended up going in a different direction. Nevertheless, this is a well-thought-out detection process for cyanotoxins. Furthermore, you have proposed a novel mitigation tactic for HABs, which is amazing! However, this is the process that I need a little clarification on. To my understanding, the intent is to use the magnetic photocatalyst nanoparticles to deactivate toxigenic cyanobacteria (ideally cyanobacteria capable of producing toxins but not doing so, yet) and adsorb phosphorus (a contributing nutrient to ABs). I understand that the nanomaterial is magnetic so it can be removed from the water to be reused, but so far this has only been demonstrated with water samples. While your mitigation strategy will be further developed in phase 2, I am curious if you have started brainstorming the water treatment process. In other words, how do you anticipate introducing the nanoparticles to and removing them from a water body (in-situ)?
