Biogenic nanoparticles (BNPs) have emerged as promising tools within biotechnology, providing an eco-friendly and sustainable alternative to chemically synthesized nanomaterials. Their distinctive biological and physicochemical properties offer enhanced biocompatibility, reduced toxicity, and environmentally friendly production methods, making them highly attractive across multiple biotechnological fields. Recent studies have showcased their effectiveness in antimicrobial strategies, drug delivery systems, environmental remediation, biosensing applications, and advancements in agriculture. Despite significant progress in these areas, challenges persist in fully understanding and optimizing BNP synthesis processes, elucidating their interaction mechanisms with biological systems, and systematically establishing their environmental impact and safety profiles.

This Research Topic aims to showcase the latest advances in biogenic nanoparticle technology, with special attention on their synthesis methodologies, detailed physicochemical and biological characterization, and diverse applications across biomedical and environmental biotechnology, as well as agricultural and food-related developments. Essential research questions include improving the efficiency and scalability of BNP synthesis, exploring novel avenues for their application in combating antimicrobial resistance, enhancing therapeutic delivery and regenerative medicine, addressing critical environmental concerns, and fostering sustainable agricultural practices. By doing so, this collection endeavors to promote innovative research perspectives, address existing knowledge gaps, and bridge different scientific disciplines to innovate sustainable biotechnological solutions.

To gather further insights in the synthesis, characterization, and biotechnological applications of BNPs, we welcome articles addressing, but not limited to, the following themes:
