Abstract : Growing environmental concerns have driven the development of sustainable nanoparticle synthesis methods, with microwave-assisted green synthesis emerging as an efficient and eco-friendly approach. This technique combine rapid, uniform microwave heating with green chemistry principles, decreases need of excess energy, waste production, and the use of high-risk chemicals. In this study, Tinospora cordifolia stem extract used as a reducing and stabilizing agent, while ferric (III) chloride (FeCl₃) used as the precursor reagent for the synthesis of iron oxide nanoparticles. Bioactive phytochemicals such as phenolics and flavonoids facilitated the reduction of Fe³⁺ ions and prevented particle agglomeration. UV–Visible spectroscopy (200–800 nm) confirmed nanoparticle formation, showing a characteristic absorption peak at 341.6 nm. SEM (Scanning electron microscopy) explained the particles within the broad size range of 30–65 nm and variable surface morphology. Overall, microwave irradiation enhanced reaction kinetics and enabled rapid, controlled, and sustainable production of iron oxide nanoparticles.
