“…It is mostly determined using spectroscopic techniques, which may be paired with microscopy to attain singleparticle-level resolution, with the most often used methods being XRD [101,180,183,184], EDS [11,119,183], and EDX [172,[185][186][187]. Because the nanoparticle's external layer interacts with the surrounding environment, determining its composition (surface chemistry) is also important and can be obtained using different techniques like Auger electron spectroscopy [188,189], X-ray photoelectron spectroscopy [190][191][192], or inductively coupled plasma mass spectrometry [193].…”

The rise of antimicrobial resistance caused by inappropriate use of these agents in various settings has become a global health threat. Nanotechnology offers the potential for the synthesis of nanoparticles (NPs) with antimicrobial activity, such as iron oxide nanoparticles (IONPs). The use of IONPs is a promising way to overcome antimicrobial resistance or pathogenicity because of their ability to interact with several biological molecules and to inhibit microbial growth. In this review, we outline the pivotal findings over the past decade concerning methods for the green synthesis of IONPs using bacteria, fungi, plants, and organic waste. Subsequently, we delve into the primary challenges encountered in green synthesis utilizing diverse organisms and organic materials. Furthermore, we compile the most common methods employed for the characterization of these IONPs. To conclude, we highlight the applications of these IONPs as promising antibacterial, antifungal, antiparasitic, and antiviral agents.

The advancement in nanotechnology has completely revolutionized various fields, including pharmaceutical sciences, and streamlined the potential therapeutic of many diseases that endanger human life. The synthesis of green nanoparticles by biological processes is an aspect of the newly emerging scientific field known as "green nanotechnology". Due to their safe, eco-friendly, nontoxic nature, green synthesis tools are better suited to produce nanoparticles between 1 and 100 nm. Nanoformulation of different types of nanoparticles has been made possible by using green production techniques and commercially feasible novel precursors, such as seed extracts, algae, and fungi, that act as potent reducing, capping, and stabilizing agents. In addition to this, the biofunctionalization of nanoparticles has also broadened its horizon in the field of environmental remediation and various novel therapeutic innovations including wound healing, antimicrobial, anticancer, and nano biosensing. However, the major challenge pertaining to green nanotechnology is the agglomeration of nanoparticles that may alter the surface topology, which can affect biological physiology, thereby contributing to system toxicity. Therefore, a thorough grasp of nanoparticle toxicity and biocompatibility is required to harness the applications of nanotechnology in therapeutics.

“…In recent years, various nanozymes have been exploited to replace natural enzymes for catalytic CL system to achieve signal amplification, which further improves the stability, expands the application and reduces the cost of CL. The Fe 3 O 4 nanoparticle (MNPs) was the first reported nanozyme ( Fan et al, 2017 ) and has been widely used in pharmacy ( Wei et al, 2021 ), catalytic therapy( Meng et al, 2021 ), environmental governance ( Mundekkad & Alex, 2022 ) and biosensing ( Huang et al, 2022 ) due to its intrinsic peroxidase-like activity. Furthermore, TCs have a strong tendency to couple with metal ions such as Fe 3+ , Fe 2+ , Fe-TC complex can generate reactive oxygen species (ROS) (primarily ·OH) in the presence of dissolved oxygen (H. Wang, Yao, Sun, Li, & Huang, 2015 ).…”
