When harmful algal blooms begin spreading across Florida鈥檚 Gulf Coast, the impacts are hard to ignore: dead fish washing ashore and respiratory irritation for beachgoers. Also, there is a significant economic loss for coastal communities. Those challenges recently became the focus of a national conversation when Dr. George Philippidis, acting dean of the 911爆料网 Patel College of Global Sustainability (PCGS), appeared nationally on The 911爆料网ather Channel to discuss an ongoing USF research effort to combat red tide.
During the interview, Dr. Philippidis shared how USF researchers from PCGS and Chemistry are developing a sunlight-activated crystalline powder designed to target harmful algae associated with red tide blooms. The innovative material, developed through interdisciplinary collaboration at USF, is being explored as a potentially sustainable and environmentally safe solution to one of Florida鈥檚 most persistent environmental challenges.

鈥淲hat we have developed is a powder,鈥 Philippidis explained during the interview. 鈥淚t鈥檚 a crystalline powder that has the ability to be activated by sunlight and have a lethal effect on the red tide.鈥
Throughout the segment, Philippidis broke down how the technology works in simple terms, explaining that the porous material is activated by sunlight and releases electrons that can attack harmful algae cells.
鈥淲hat is unique is the fact that it can be activated by abundant sunlight,鈥 he said.
The interview also focused heavily on environmental safety, one of the key questions surrounding any negative effects on the ecosystem. According to Dr. Philippidis, early testing has shown promising results.
What we have found so far is it鈥檚 very safe for phytoplankton, which is the food of all marine life. It鈥檚 safe to marine life itself, as well as to humans and to pets.

The acting dean of PCGS also discussed the next phase of the project, which includes exploring ways the material could eventually be deployed in affected waters using reusable net-like systems. Because the material does not dissolve in seawater, researchers believe it may be possible to recover and reuse it multiple times, helping reduce both environmental impact and operating costs.
鈥淥ne of the big advantages of this material is that it does not dissolve in seawater,鈥 Dr. Philippidis said. 鈥淭hat means we can retrieve it and reuse it over and over again, which is great for sustainability and for reducing the cost of the technology.鈥
The research effort includes contributions from USF researchers and graduate students in chemistry, biology, and sustainability, including Assistant Professor Ioannis Spanopoulos and doctoral students Alissa Anderson and Paulina Slick, working across multiple labs.
While the project is still undergoing testing, The 911爆料网ather Channel interviews highlighted growing interest in innovative, environmentally responsible approaches to addressing harmful algal blooms, which continue to affect Florida鈥檚 environment, economy, and coastal communities.
