“…In addition to nano-therapies, nano-diagnostic agents-metal nanoparticles-have been indicated to be highly applicable in the detection of viruses, including covid-19 (Fouad 2021). Several biotic [e.g., algae (AlNadhari et al 2021) and viral capsid (Jeevanandam et al 2019)] and abiotic [e.g., gold, silver, graphene oxide, and zin oxide (Fouad 2021)] nanomaterials have been reported to be applicable in biomedical processes. The combination of biotic and abiotic sources provides efficient nanomaterials as well.…”

Nanotechnology is one of the most emerging fields of research within recent decades and is based upon the exploitation of nano-sized materials (e.g., nanoparticles, nanotubes, nanomembranes, nanowires, nanofibers and so on) in various operational fields. Nanomaterials have multiple advantages, including high stability, target selectivity, and plasticity. Diverse biotic (e.g., Capsid of viruses and algae) and abiotic (e.g., Carbon, silver, gold and etc.) materials can be utilized in the synthesis process of nanomaterials. "Nanobiotechnology" is the combination of nanotechnology and biotechnology disciplines. Nano-based approaches are developed to improve the traditional biotechnological methods and overcome their limitations, such as the side effects caused by conventional therapies. Several studies have reported that nanobiotechnology has remarkably enhanced the efficiency of various techniques, including drug delivery, water and soil remediation, and enzymatic processes. In this review, techniques that benefit the most from nano-biotechnological approaches, are categorized into four major fields: medical, industrial, agricultural, and environmental.

“…Over the last decades, various NMs have been biosynthesized, typically metallic [43,44], metalloid [45], oxides [46][47][48][49], carbonates [50,51], and chalcogenide [52,53]. On the other hand, countless studies have reported the biosynthesis of NMs using various biological entities [54,55], such as bacteria and actinomycetes [10,56,57], fungi and yeast [10,[58][59][60][61], plant extracts [62,63], algae [64,65], viruses [66], and biomolecules [67][68][69].…”

Bio-nanotechnology has emerged as an efficient and competitive methodology for the production of added-value nanomaterials (NMs). This review article gathers knowledge gleaned from the literature regarding the biosynthesis of sulfur-based chalcogenide nanoparticles (S-NPs), such as CdS, ZnS and PbS NPs, using various biological resources, namely bacteria, fungi including yeast, algae, plant extracts, single biomolecules, and viruses. In addition, this work sheds light onto the hypothetical mechanistic aspects, and discusses the impact of varying the experimental parameters, such as the employed bio-entity, time, pH, and biomass concentration, on the obtained S-NPs and, consequently, on their properties. Furthermore, various bio-applications of these NMs are described. Finally, key elements regarding the whole process are summed up and some hints are provided to overcome encountered bottlenecks towards the improved and scalable production of biogenic S-NPs.

“…Although bacteria have cornered more attention in metal biomineralization, contributions from fungal (Hu et al, 2019) and algal (AlNadhari et al, 2020) species cannot be ignored. Fungi is known to secrete many enzymes and organic acids, particularly oxalic acid, that play a pivotal role in metal biotransformation forming metal complexes such as metaloxalates.…”

The emergence of nanosystems for different biomedical and drug delivery applications has drawn the attention of researchers worldwide. The likeness of microorganisms including bacteria, yeast, algae, fungi, and even viruses toward metals is well-known. Higher tolerance to toxic metals has opened up new avenues of designing microbial fabricated nanomaterials. Their synthesis, characterization and applications in bioremediation, biomineralization, and as a chelating agent has been well-documented and reviewed. Further, these materials, due to their ability to get functionalized, can also be used as theranostics i.e., both therapeutic as well as diagnostic agents in a single unit. Current article attempts to focus particularly on the application of such microbially derived nanoformulations as a drug delivery and targeting agent. Besides metal-based nanoparticles, there is enough evidence wherein nanoparticles have been formulated using only the organic component of microorganisms. Enzymes, peptides, polysaccharides, polyhydroxyalkanoate (PHA), poly-(amino acids) are amongst the most used biomolecules for guiding crystal growth and as a capping/reducing agent in the fabrication of nanoparticles. This has promulgated the idea of complete green chemistry biosynthesis of nano-organics that are most sought after in terms of their biocompatibility and bioavailability.
