“…The synthesis of CuO-NPs by A. tucumanensis AB0 introduces the genus into the field of nano-biotechnology. CuO-NPs may be used as anticancer molecules, to improve antiviral functions and bioremediation processes [49][50][51]. Further studies will be focused on the characterization and potential application of these nanoparticles.…”

Through the years, the genus Amycolatopsis has demonstrated its biotechnological potential. The need to clean up the environment and produce new antimicrobial molecules led to exploit promising bacterial genera such as Amycolatopsis. In this present work, we analyze the genome of the strain Amycolatopsis tucumanensis AB0 previously isolated from copper-polluted sediments. Phylogenomic and comparative analysis with the closest phylogenetic neighbor was performed. Our analysis showed the genetic potential of

“…Cuprous and copper oxide NPs are other nanomaterials with potential applications in the biomedical field [101]. In particular, plant-synthesized NPs showed pharmacological effects in tumor therapy, such as inducing apoptosis, increasing ROS generation, inhibiting metastasis, and stimulating autophagic cell death [1,6] in colon cancer [102,103], esophageal cancer [104], lung cancer [105], breast cancer [106], cervical cancer [107], renal cell carcinoma [108], and melanoma [109].…”

Cancer continues to represent a global health concern, imposing an ongoing need to research for better treatment alternatives. In this context, nanomedicine seems to be the solution to existing problems, bringing unprecedented results in various biomedical applications, including cancer therapy, diagnosing, and imaging. As numerous studies have uncovered the advantageous properties of various nanoscale metals, this review aims to present metal-based nanoparticles that are most frequently employed for cancer applications. This paper follows the description of relevant nanoparticles made of metals, metal derivatives, hybrids, and alloys, further discussing in more detail their potential applications in cancer management, ranging from the delivery of chemotherapeutics, vaccines, and genes to ablative hyperthermia therapies and theranostic platforms.

“…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.…”

“…CuO NPs synthesized by the endophytic fungus Aspergillus terreus FCBY1 isolated from a tropical plant Aegle marmelos were tested by Mani et al (2021) against Staphylococcus epidermidis, Candida albicans, Proteus mirabilis, Vibrio cholerae, Salmonella typhi, S. aureus, P. aeruginosa, K. pnuemoniae, E. coli and A. niger. It was shown that all microorganisms had their growth inhibited by CuO NPsalthough the inhibition of fungi was lower than that of bacteria.…”

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.
