“…A cheaper alternative to both Ag NPs and Au NPs are Cu NPs. It was found that the fungus Aspergillus terreus isolated from the plants Aegle marmelosa and Origanum majorana is capable of producing spheroidal CuO NPs from CuSO 4 (Mani et al, 2021;Mousa et al, 2021). In this case, the use of biomass and cell extract of the fungus led to the formation of CuO NPs with different sizes.…”

Nanoparticles (NPs) have gained great attention in recent years due to their extensive and innovative applications in the field of medicine. However, conventional physicochemical approaches for the synthesis of NPs may be limited and costly, and the reaction by-products are potentially toxic for human health and the environment. Bio-mediated synthesis of NPs exploiting microorganisms as nanofactories has emerged as an alternative to traditional methods, as it provides economic and environmental benefits. Tropical ecosystems harbor a high diversity of endophytes, which have a diverse array of metabolic pathways that confer habitat adaptation and survival and that can be used to produce novel bioactive compounds with a variety of biological properties. Endophytic bacteria and fungi cultivated under optimum conditions have potential for use in biogenic synthesis of NPs with different characteristics and desired activities for medical applications, such as antimicrobial, antitumoral, antioxidant and anti-inflammatory properties. The bio-mediated synthesis of metal-based NPs can be favored because endophytic microorganisms may tolerate and/or adsorb metals and produce enzymes used as reducing agents. To our knowledge, this is the first review that brings together exclusively current research highlighting on the potential of endophytic bacteria and fungi isolated from native plants or adapted to tropical ecosystems and tropical macroalgae as nanofactories for the synthesis of NPs of silver, gold, copper, iron, zinc and other most studied metals, in addition to showing their potential use in human health.

“…The antifungal activity was observed in the ZnO NPs, which were synthesized by Aspergillus terreus [90]. Recently, Mausa et al, [119] reported the mycosynthesis of various NMs viz. Co 3 O 4 , CuO, Fe 3 O 4 , NiO, and ZnO NPs by endophytic fungus Aspergillus terreus, and studied its antimicrobial and antioxidant activities, which leads to their application in different fields.…”

“…In medicine and pharmacy, NMs have been successfully applied due to their high surface area that is able to adsorbed or conjugate with an extensive variety of therapeutic and diagnostic agents such as drugs, vaccines, genes, antibodies, and biosensors. In recent years, antibiotic resistance is an emerging major global health problem and novel antimicrobial formulations are essentially needed to fight against these drug-resistant microbes, therefore nano-based medicine as antimicrobial agents have gained considerable attention in the field of microbial drug resistance [119,120]. Hence, the NPs synthesized by Mousa et al, [119] using the endophytic fungus Aspergillus terreus were studied to discover their efficacy against different multi-drug-resistant bacterial strains as well as some human and plant pathogenic fungi.…”

There is a great demand for green methods of synthesis of nanoparticles. Fungi play an important role in the synthesis of nanoparticles, of which Aspergillus spp. are known to secrete different enzymes responsible for the synthesis of nanoparticles. The process of biosynthesis of nanoparticles is simple, rapid, cost-effective, eco-friendly, and easy to synthesize at ambient temperature and pressure. Mostly, the metal nanoparticles such as silver, gold, lead and the oxides of titanium, zinc, and copper are synthesized from Aspergillus spp. These include mainly Aspergillus fumigatus, A. flavus, A. niger, A. terreus, and A. clavatus. The fabrication of different nanoparticles is extracellular. In the present chapter, we have discussed the role of different species of Aspergillus, mechanism of biogenic synthesis particularly enzymes involved in the reduction of metal ions into nanoparticles. The biogenically synthesized nanoparticles have demonstrated several biomedicals, agricultural, and engineering applications. The biogenic nanoparticles are mostly used as antimicrobial and cytotoxic agents. Their use as fungicidal agents is important for sustainable agriculture.

“…In recent years, nanoscaled antibacterial materials are expected to become signi cant antimicrobial elements due to their novel physical and chemical potential, more importantly, its broad-spectrum antimicrobial activity. Currently, nanoscaled antibacterial materials include TiO 2 , ZnO, CuO, Ca(HO) 2 , MgO, chitosan, silver, and others [2][3][4][5][6][7][8] . Among them, nanocrystalline silver and its compounds can e ciently inhibit or even kill pathogenic bacteria, viruses and other microorganisms, which has the advantage of lower toxicity and side effects and plays an important role in local bacteriostatic therapy.…”

In this study, we prepared a new type of recyclable Co@Ag core–shell nanomaterials with a very simple method named displacement reaction. Co@Ag core–shell nanomaterials were prepared in AgNO3 solution with cobalt nanomaterials as the core, while the surface was coated with silver nanomaterials. Co@Ag core–shell nanomaterials were characterized by transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD) and oscillating sample magnetometer (VSM).We found that the diameter of the Co@Ag core–shell nanomaterials was about 100nm, which was exhibited in form of elemental elements andobvious magnetic properties.In order to evaluate the bacteriostatic effect of Co@Ag core–shell nanomaterials, we used qualitative and quantitative methods to assess the bacteriostatic effect of these materials on standard strains of Pseudomonas aeruginosa (ATCC27853, Gram - negative bacterium), Staphylococcus aureus (ATCC 25923, Gram-positive bacterium), Escherichia coli (ATCC 25922, Gram-negative bacterium) and Candida albicans (ATTC 90029, yeast) in Yellow River water in vitro. The results show that Co@Ag core–shell nanomaterials have a significant antibacterial effect. In addition, Co@Ag core–shell nanomaterials can be recycled through an external magnetic field to reduce environmental pollution. Interestingly, the reclaimed Co@Ag core–shell nanomaterials can still have antibacterial activity and can be reused. These results indicate that Co@Ag core–shell nanomaterials may have potential application as disinfectants for water.
