Silver nanoparticles were successfully produced through a biological method using an aqueous leaf extract of the plant Ambrosia maritima to reduce silver nitrate. The resulting metallic particles were analysed using electron microscopy, spectroscopy, and electrochemical techniques to determine their physical and chemical attributes. The particles were primarily spherical with an average diameter of 30 nanometres, demonstrating stability reflected by a negative zeta potential of minus 26.29 millivolts. Optical testing identified a surface plasmon resonance peak at 437 nanometres alongside a fluorescence emission peak at 467 nanometres, while electrochemical evaluations recorded an anodic peak at 0.4 millivolts. These distinct properties demonstrate the feasibility of using this plant-based method to synthesise stable nanoparticles, providing a baseline for further in vitro and in vivo testing across various industrial and medical settings.
Using plant extracts provides an alternative route for generating nanomaterials with distinct optical and electrochemical properties. Demonstrating that Ambrosia maritima leaves can yield stable, spherical silver nanoparticles offers scientists a biological synthesis option. Understanding these physical and chemical benchmarks is an essential early step for researchers exploring green nanotechnology for laboratory, medical, and industrial use.
The abstract suggests general relevance to industrial and medical applications, but the technology is at an early research stage. Potential end users include biomedical product developers and materials researchers seeking biosynthesised nanoparticles. Significant distance from commercial use remains, as the abstract indicates the material has only undergone physical and optical characterisation and currently requires extensive in vitro and in vivo validation.

Silver nanoparticles (AgNPs) were biosynthesised by reducing silver nitrate (AgNO 3 ) using Ambrosia maritima aqueous leaves extract. The biosynthesised AgNPs were characterised by transmission electron microscope, Fourier transform infrared spectroscopy and zeta potential analyser. The nanoparticles were generally found to be spherical in shape with average size of 30 nm and were stable at zeta potential of −26.29 mV. The data collected by cyclic voltammetry, ultraviolet–visible (UV–Vis) spectrophotometer and spectrofluorophotometer proved the characteristic electrochemical and optical properties of the biosynthesised AgNPs. The metallic nanoparticles showed an anodic peak at 0.4 mV, a surface plasmon resonance peak at 437 nm and a fluorescence emission peak at the wavelength of 467 nm. In conclusion, AgNPs biosynthesised using A . maritima proved to be compatible and feasible to be studied further in in vitro and in vivo systems. Overall, the biosynthesised AgNPs can be used as a tool applied in a broad range of industrial and medical applications.
