“…Since, nanotechnology is gaining impetus at a faster pace, it may become a crucial and most useful component of agriculture industry, the phototoxicity of synthesized AgNPs could be repressed by coating the powdered AgNPs with biocompatible materials such as polyvinyl pyrrole [ 196 ]. The toxicity and use cases of Ag-based nanomaterials and AgNPs have been well-established by the Environmental Protection Agency (EPA) [ 6 , 197 ]. In a report, it was claimed that the formulations of >100 pesticides contain AgNPs, which are incorporated as antimicrobial agents.…”

“…This necessitates the development of alternative strategies to control plant diseases. In this regard, nanotechnology seems to be an alternative; it has also progressed significantly in the field of medicine, e.g., as alternative antimicrobials [ 4 , 5 , 6 ] and pharmacology, e.g., for drug delivery. However, it has attracted relatively less support in precision agriculture [ 7 ].…”

Exploration of nanoparticles (NPs) for various biological and environmental applications has become one of the most important attributes of nanotechnology. Due to remarkable physicochemical properties, silver nanoparticles (AgNPs) are the most explored and used NPs in wide-ranging applications. Also, they have proven to be of high commercial use since they possess great chemical stability, conductivity, catalytic activity, and antimicrobial potential. Though several methods including chemical and physical methods have been devised, biological approaches using organisms such as bacteria, fungi, and plants have emerged as economical, safe, and effective alternatives for the biosynthesis of AgNPs. Recent studies highlight the potential of AgNPs in modern agricultural practices to control the growth and spread of infectious pathogenic microorganisms since the introduction of AgNPs effectively reduces plant diseases caused by a spectrum of bacteria and fungi. In this review, we highlight the biosynthesis of AgNPs and discuss their applications in plant disease management with recent examples. It is proposed that AgNPs are prospective NPs for the successful inhibition of pathogen growth and plant disease management. This review gives a better understanding of new biological approaches for AgNP synthesis and modes of their optimized applications that could contribute to sustainable agriculture.

“…In Figure 4, FeVO 4 shows a typical absorption of semiconductor solid, and its bandgap energy was calculated to be 2.17 eV according to the Tauc plot [10d] . For FeVO 4 @Al 2 O 3 ‐x, no significant change in optical properties was disclosed, since the Al 2 O 3 layer with a bandgap energy of 3.94 eV is colorless and transparent [17] . The wrapping of FeVO 4 nanorods with a ultrathin Al 2 O 3 layer did not block the incident light, which was very important for photocatalysis.…”

Improved Durability and Activity of FeVO₄ toward Photocatalytic Benzene Hydroxylation by Atomic Layer Deposited Al₂O₃

et al. 2022

Selective hydroxylation of benzene to phenol over a visible light driven photocatalyst is a sustainable approach for the green synthesis of phenol. Iron vanadate (FeVO4) nanorods with an intrinsic photo‐Fenton catalytic behavior toward H2O2 activation is a promising candidate photocatalyst for the benzene hydroxylation reaction; however, its photocatalytic performance was greatly limited by the serious leaching of metals during the hydroxylation process. Herein, it has been demonstrated that this issue can be well addressed by the conformably coating of FeVO4 nanorods with an atomically‐precise thickness controlled dense Al2O3 layer (FeVO4@Al2O3) through the atomic layer deposition (ALD) technology. The Al2O3 nanolayer can well protect the FeVO4 nanorods from directly contacting with the reaction solution, thus effectively suppressing the leaching of metals during the photocatalytic hydroxylation process. In addition, the Al2O3 coating on FeVO4 also facilitates the kinetic control of heterogeneous benzene hydroxylation reaction over the catalyst surface, such as the benzene adsorption behavior and the photo‐Fenton activation of H2O2. As a result, FeVO4@Al2O3 exhibited an enhanced photocatalytic performance with a good durability in the long‐term production of phenol.

Antibacterial Nanomaterials: Mechanisms, Impacts on Antimicrobial Resistance and Design Principles

et al. 2023

Antimicrobial resistance (AMR) is one of the biggest threats to the environment and health. AMR rapidly invalidates conventional antibiotics, and antimicrobial nanomaterials have been increasingly explored as alternatives. Interestingly, several antimicrobial nanomaterials show AMR‐independent antimicrobial effects without detectable new resistance and have therefore been suggested to prevent AMR evolution. In contrast, some are found to trigger the evolution of AMR. Given these seemingly conflicting findings, a timely discussion of the two faces of antimicrobial nanomaterials is urgently needed. This review systematically compares the killing mechanisms and structure‐activity relationships of antibiotics and antimicrobial nanomaterials. We then focus on nano‐microbe interactions to elucidate the impacts of molecular initiating events on AMR evolution. Finally, we provide an outlook on future antimicrobial nanomaterials and propose design principles for the prevention of AMR evolution.
