“…High concentrations of antibiotics present in residual sludge not only inhibit the methanogenic process of anaerobic digestion of sludge, but also pose an environmental risk ( Ni et al, 2020 ). Zhou et al (2021a) used ZVI powder to enhance anaerobic digestion of medium-temperature sludge and found that the anaerobic reactor could remove sulfamidine, sulfamethoxazole, tetracycline, and roxithromycin up to 97.39, 74.54, 78.61, and 56.58%, respectively. After the application of 1 g/L of ZVI, the abundance of AAC (6′)-IB-CR and tetB was significantly reduced compared to the control group without ZVI ( Zhou et al, 2021a ).…”

Xiang et al’s (2019) study showed that enhanced anaerobic digestion of municipal sludge using nZVI contributed to the removal of ermA and ermT ( Xiang et al, 2019 ); Zhang et al (2020) used Fe 3 O 4 nanoparticles and nZVI for enhanced anaerobic digestion of municipal sludge and found that the removal of total ARGs by both iron nanoparticles was 70.73 and 62.69%, respectively.…”

The environmental and epidemiological problems caused by antibiotics and antibiotic resistance genes have attracted a lot of attention. The use of electron shuttles based on enhanced extracellular electron transfer for anaerobic biological treatment to remove widespread antibiotics and antibiotic resistance genes efficiently from wastewater or organic solid waste is a promising technology. This paper reviewed the development of electron shuttles, described the mechanism of action of different electron shuttles and the application of enhanced anaerobic biotreatment with electron shuttles for the removal of antibiotics and related genes. Finally, we discussed the current issues and possible future directions of electron shuttle technology.

“…Paromomycin, a noteworthy aminoglycoside antibiotic with anti‐leishmanial activity, yet has become less significant, at present, due to its decreased permeability inside the macrophage. Therefore, the multidrug resistance and antibiotic‐resistant strains of bacteria have been imposed as the foremost health issues in transmitting zoonotic diseases [16] . Chemotherapeutics at hand cannot treat infection due to multiple drug resistance, lack of oral bioavailability, decreased permeability, toxicity, and high cost.…”

[16] Chemotherapeutics at hand cannot treat infection due to multiple drug resistance, lack of oral bioavailability, decreased permeability, toxicity, and high cost. The first-line drug treatment failure resulting from resistance has affirmed the strategy of developing novel nano formulations owing to their targeted action and improved bioavailability.…”

Zoonotic infections belong to multiple infectious diseases transferred from animals to humans. Now, the treatment and diagnosis of zoonotic infections are perplexing due to genetic mutations, target site modifications, and multi‐drug resistance. Despite their benefits, most diagnostic molecular techniques have certain limits in terms of repeatability and sensitivity, mainly due to the heterogeneity among the diverse family of zoonotic pathogens. Therefore, developing more efficient and cost‐effective theranostics tools is the need of the hour to address these concerns. For this purpose, nanotechnology has revolutionized medicine with versatile potential capabilities for diagnosing and treating zoonosis via the targeted and controlled delivery of antimicrobial drugs via binding to the overexpressed infectious macrophages. Massive advancements have been made in fabricating novel nano‐based formulations to control zoonosis based on the use of poly(ethylenimine)‐conjugated nanomicelles, mannosylated thiolated chitosan (MTC)‐coated PM‐loaded PLGA NPs, mannose linked thiolated nanocarriers, adjuvanted pDNA hydrogel, arginine‐based nanocarriers, quantum dots to treat and diagnose a wide range of zoonotic diseases, including zoonotic influenza, salmonellosis, leishmaniasis, rabies, brucellosis, Lyme Disease, tuberculosis, and other infections caused by West Nile Virus, emerging coronaviruses (SARS, MERS, COVID‐19), in a preferentially targeted way. Recently developed anti‐pathogen loaded‐nanoformulations with enhanced cellular uptake, biocompatibility, and hemocompatibility have shown the ability to cross biological barriers when orally administrated. Therefore, this article reviewed the latest milestones and future growth areas in the field of efficient theranostics platforms to manage zoonotic infections.

“…Nanoadsorbents have been reported as a new generation of adsorbents with higher adsorption capacity, making them more e cient for the adsorption of antibiotics and other emerging pollutants [15,16,18,19,31]. Furthermore, there are numerous nanoadsorbents used to remove antibiotics, including graphene-based nanoadsorbents [33], gold nanoparticles [34], zero-valent iron (ZVI) nanoparticles [35] and titanium dioxide nanoparticles [36]. Filtration and centrifugation methods are used to separate the nonmagnetic adsorbents from an aqueous solution [37].…”

This study aimed to synthesize Fe 3 O 4 @Methylcellulose/3-Aminopropyltrimethoxysilane (Fe 3 O 4 @MC/APTMS) as a new magnetic nano-biocomposite by a facile, fast, and new microwave-assisted method and to be utilized as an adsorbent for tetracycline (TC) removal from aqueous solutions. Fe 3 O 4 @MC/APTMS was characterized by Fourier transform-infrared (FTIR), Field emission scanning electron microscopy (FESEM), Energy dispersive spectroscopy (EDS), Mapping, X-ray diffraction (XRD), Thermal gravimetric analysis (TGA), Brunauer-Emmett-Teller (BET) and vibrating sample magnetometer (VSM). The point of zero charge (pH zpc ) value of the nano-biocomposite was estimated to be 6.8 by the solid addition method.Optimum conditions were obtained in TC concentration: 10 mg L −1 , adsorbent dosage: 80 mg L −1 , contact time: 90 min, and solution pH: 6 with the maximum TC removal of 90% and 65.41% in synthetic and actual samples, respectively. The kinetic and isotherm equations pointed to a pseudosecond order kinetic and Langmuir isotherm optimum tting models. Based on the values of entropy changes (ΔS) (50.04 J/mol k), the enthalpy changes (ΔH) (9.26 kJ/mol), and the negative Gibbs free energy changes (ΔG), the adsorption process was endothermic, random, and spontaneous.The synthesized adsorbent exhibited outstanding properties, including proper removal e ciency of TC, excellent reusability, and simple separation from aqueous media by a magnet. Consequently, it is highly desirable that Fe 3 O 4 @MC/APTMS magnetic nano-biocomposite could be used as a promising adsorbent for TC adsorption from aqueous solutions. HighlightsFe 3 O 4 @MC/APTMSas a new magnetic nano-biocomposite has been synthesized by a new microwave-assisted method and characterized with FESEM, EDS, Mapping, FT-IR, XRD, TGA, BET, and VSM techniques.The maximum removal e ciencies under optimal conditions (pH=6, TC concentration 10 mg L -1 , adsorbent dosage: 80 mg L -1 and contact time: 90 min) for synthetic and actual samples were obtained 90% and 65.41%, respectively.Isotherm, kinetic and thermodynamic study of tetracycline adsorption were investigated.Fe 3 O 4 @MC/APTMS exhibited excellentreusability property up to 5 cycles.
