Abstract
Water pollution is a global issue that threatens human health and ecosystems, driving the need for advanced purification technologies. Traditional methods face limitations in cost and efficiency, prompting the emergence of green nanomicrobiology as a sustainable alternative. This interdisciplinary approach integrates nanotechnology and microbiology to develop advanced materials capable of eliminating contaminants. To assess scientific advancements in this field, a bibliometric analysis was conducted based on publications indexed in Scopus, utilizing tools such as VOSviewer 1.6.20 and RStudio 2025.09 to identify trends, institutional collaborations, and development patterns. The findings reveal a significant increase in scientific output between 2010 and 2025, with growing research on nanocomposites, adsorption processes, and hybrid microbiological systems. Notably, metallic nanoparticles and functionalized biopolymers, such as modified bacterial cellulose, demonstrate high efficiency in removing heavy metals and toxic residues. The study also highlights China’s pivotal role in scientific collaboration, with an expanding network of partnerships. Despite these advancements, challenges remain regarding industrial scalability, long-term toxicity, and regulatory frameworks. Integrating artificial intelligence and metagenomics could enhance these systems, strengthening their impact on water sustainability.
