Abstract Iron oxide nanoparticles (IONPs) were prepared by biosynthesis method using Aegle marmelos extract followed by calcination at 400 °C. Synthesised IONPs were characterized by UV–Vis spectroscopy, X-Ray diffraction technique, Fourier transform infrared spectroscopy, Scanning electron microscopy and Energy dispersive spectroscopy, Zeta potential and Dynamic light scattering analysis. Furthermore, Antifungal activity of the synthesised IONPs was tested against soil isolated plant pathogenic fungi F.solani (12 ± 0.53 mm) compared with fluconazole (7 ± 0.38) at 30 µg/ml. The antimicrobial activity of the IONPs was tested against E.coli (21 ± 0.43 and 30 ± 0.38 mm) and S.aureus (19 ± 0.54 and 28 ± 0.65 mm) at 15 and 30 µg/ml concentration respectively and compared with Streptomycin (16 ± 0.43 and 22 ± 0.34 at 15 and 30 µg/ml). Photocatalytic activity of the synthesised IONPs was studied using Brilliant green dye under UV light. 95.89% degradation was observed in 90 min. The photocatalytic degradation followed the first order kinetics model and the K value was 0.0458 m in−1.

1 Introduction Nanoparticles with well-defined structures and shapes along with unique physical and chemical properties played vital role in nanotechnology and catalysis [1]. Physical and chemical properties of Iron Oxide Nano Particles (IONPs) has been applied in several fields considerably [2]. IONPs possess significant antimicrobial properties against bacteria and fungi under harsh circumstances [3]. The green synthesised IONPs has been considered as an eco-friendly, cost effective and alternate medicine for the inhibition of human pathogenic microbes [4]. IONPs are found to be more stable and harmless to human beings [5]. IONPs—a significant material involved in various areas like magnetic hyperthermia, drug delivery and biosensor [6]. IONPs have been widely

used in solar energy conversion, photo catalyst, magnetic storage devices, biomaterials and tissue repair agent [7–10]. There are many methods developed for the synthesis of IONPs which includes biosynthesis, physical and chemical methods. There are demerits seen in physical and chemical methods such as short-term stability, toxic and safety issues [11]. Keeping this in mind and considering safety to our environment, there is lot
