Core Viewpoint - The research team from Central South University, in collaboration with other universities, has developed an innovative microbubble flotation technology for marine plastic pollution management, providing a new approach to tackle the growing issue of microplastic contamination in oceans [1][2]. Group 1: Research Findings - The study reveals a bidirectional regulatory mechanism of algal extracellular polymers in the microplastic flotation process, enhancing the stability of microbubbles and precisely regulating the surface characteristics of microplastics [1]. - Compared to conventional flotation methods, microbubble flotation shows potential due to its small size and high stability, although complex interfacial interactions in marine environments pose significant challenges [1][2]. - Algal extracellular polymers induce hydrophilization of microplastic surfaces, weakening the hydrophobic interactions between microplastics and microbubbles, which significantly reduces the efficiency of conventional flotation methods in removing microplastics from seawater [2]. Group 2: Implications for Technology - The findings provide new insights into interfacial interactions in marine microplastic flotation and establish a theoretical foundation for the application of microbubble flotation technology in addressing marine microplastic pollution [2].
