Abstract Objective The purpose of this study was to develop ecofriendly and sustainable copper nanoparticles (CuNPs) using Padina pavonica extract. CuNPs were characterized scanning electron microscopy (SEM) for morphological analysis, energy dispersive X-ray (EDS) spectroscopy elemental composition, Fourier transform infrared (FTIR) functional group identification, UV-visible optical properties. We evaluated the toxicity survival rates Guppy Poecilia reticulata larvae that subjected varied CuNP concentrations determine best concentration range future aquaculture uses. Methods different characterization stability synthesized investigated SEM, EDS, FTIR, spectroscopy. To evaluate safe exposure levels, exposed monitored over a 72-hour period. Results biosynthesized exhibited characteristic surface plasmon resonance peaks at 260 nm, confirming their formation, with FTIR revealing involvement groups like O-H O-SO3H in nanoparticle capping. SEM analysis showed irregular, aggregated CuNPs, sizes ranging from 50 200 nm. Energy confirmed including copper, oxygen, chlorine, carbon. Conclusions This article describes environmentally acceptable method manufacturing extract as natural reducing agent. established an appropriate by comparing concentrations. findings provide important insights into use aquaculture, which benefits both aquatic organism health environmental sustainability.

Green synthesized nanoparticles (NPs) are arousing constantly increasing attention due to inherent advantages such as biocompatibility, nontoxicity, and cost-effectiveness. As the state of art this rapidly evolving topic demands a punctual update, present study was focused on reviewing novelty, feasibility, effectiveness related specific category red seaweed-derived NPs. Among algae, seaweeds have already gained consideration in global market their high content primary secondary metabolites, supporting multifunctional applications across various industries. This scoping review reveals how interest has also driven investigation natural source for sustainable NP fabrication. The fragmentary body studies synthesized, identifying seaweed NPs flourishing nanotechnological subgroup meriting own space scientific literature. Noteworthy, great majority reviewed papers feature efficient controlled release, enhanced bioavailability, reduced toxicity, making elective candidates medical sector anticancer, antimicrobial, antioxidant agents. Moreover, parent counterparts seem endow with unexpected specificity toward biological targets prokaryotic tumor cells. Nanotechnological solutions based pave way new avenue opportunities challenges.
