Microbial Innovations Shaping Green Nanoparticle Synthesis

The field of green nanoparticle synthesis is at the forefront of sustainable science, propelled by growing environmental concerns and the demand for innovative, low-impact production methods. Traditional chemical methods for nanoparticle fabrication often entail significant environmental costs, prompting the scientific community to explore alternatives rooted in the diverse metabolic repertoire of microorganisms. While early efforts largely centered on microbial pigments, cutting-edge research now leverages a broad spectrum of microbial products and pathways ranging from enzymes and exopolysaccharides to biosurfactants and whole-cell systems to generate nanoparticles with desirable characteristics for use in medicine, environmental remediation, catalysis, and green manufacturing. Landmark studies have recently demonstrated that these biological routes can yield highly functional, biocompatible nanomaterials with greater efficiency, offering reduced toxicity and energy consumption compared to their chemically synthesized counterparts. However, challenges such as maintaining uniform product quality and achieving process scalability persist, highlighting unresolved questions regarding optimization and industrial translation.This Research Topic aims to highlight and advance the role of microbes as dynamic agents for green nanoparticle synthesis by showcasing novel approaches that transcend pigment-mediated processes. Our objective is to stimulate discussion on the latest technological innovations and fundamental discoveries, including the genetic engineering of microbial systems, process optimization for large-scale production, and the exploration of unconventional microbial metabolites or consortia. The topic seeks to address open questions about the mechanisms underlying biologically directed nanoparticle formation, strategies for overcoming current bottlenecks (such as heterogeneity), and the development of new applications that take full advantage of the inherent sustainability offered by microbial platforms.For this Research Topic, we are interested in research that explores the full diversity and potential of microbial systems for nanoparticle synthesis, while recognizing the need to critically assess scalability, product standardization, and practical impacts. To gather further insights in the field of green nanoparticle synthesis using microbial innovations, we welcome articles addressing, but not limited to, the following themes:o Mechanistic insights into microbial biosynthesis of nanoparticles beyond pigmentso Engineering of microbial metabolic pathways for custom nanomaterial productiono Scaling up processes and overcoming challenges of industrial implementationo Cell-free and microbial consortium approaches for nanoparticle fabricationo Functional applications of microbially produced nanoparticles in medicine, remediation, catalysis, and green manufacturingo Comparative analyses of biosynthetic and chemical nanoparticle synthesis methodso Environmental and life cycle impacts of microbially mediated nanoparticle productionPlease note that Microbiotechnology does not consider descriptive studies that are solely based on amplicon (e.g., 16S rRNA) profiles or comparisons of nucleic acid extracts (e.g., metagenomics), unless they are accompanied by a clear hypothesis and experimentation and provide insight into the microbiological system or process being studied.
