In the recent times, nanomaterials have emerged in the field of biology, medicine, electronics, and agriculture due to their immense applications. Owing to their nanoscale sizes, they present large surface/volume ratio, characteristic structures, and similar dimensions to biomolecules resulting in unique properties for biomedical applications. The chemical and physical methods to synthesize nanoparticles have their own limitations which can be overcome using biological methods for the synthesis. Moreover, through the biogenic synthesis route, the usage of microorganisms has offered a reliable, sustainable, safe, and environmental friendly technique for nanosynthesis. Bacterial, algal, fungal, and yeast cells are known to transport metals from their environment and convert them to elemental nanoparticle forms which are either accumulated or secreted. Additionally, robust nanocarriers have also been developed using viruses. In order to prevent aggregation and promote stabilization of the nanoparticles, capping agents are often secreted during biosynthesis. Microbial nanoparticles find biomedical applications in rapid diagnostics, imaging, biopharmaceuticals, drug delivery systems, antimicrobials, biomaterials for tissue regeneration as well as biosensors. The major challenges in therapeutic applications of microbial nanoparticles include biocompatibility, bioavailability, stability, degradation in the gastro-intestinal tract, and immune response. Thus, the current review article is focused on the microbe-mediated synthesis of various nanoparticles, the different microbial strains explored for such synthesis along with their current and future biomedical applications.

“…In a study, Abdulla et al,2021fabricated a silver-based hybrid nanocomposite having antibacterial properties for the elimination of MB dye. [21] However, the incorporation of silver in the carbon framework enhances the cost and makes the composite bit more expensive. Therefore, an economical and environmentally benign material with high performance can be a promising alternative for dye removal.…”

The preparation of Cobalt ferrite-Ocimum sanctum nanocomposite, referred to as CoFe 2 O 4 /OS, has been reported along with its application for the treatment of water containing hazardous organic contaminants. A simple co-precipitation approach was applied for synthesis of magnetic nanocomposite, and a thorough analysis for its characterization was conducted using several spectroscopic and microscopic techniques. The characterization results showed that the magnetic nanocomposite exhibited substantial functional groups of Ocimum sanctum powder and magnetic ferrite part. The adsorption investigation of nanocomposite for removal of two cationic dyes was carried out with varying parameters, such as pH, contact time, temperature, concentration, and composite dosage. The sorption process was proved feasible and exothermic at the tested temperatures (303-323 K). The sorption data followed Freundlich and Temkin isotherms which recommended the physisorption progression. The kinetic study revealed a pseudo-second order rate of sorption process for both dye molecules. The facile preparation, economical cost, significant magnetic character, and high sorption capacity will surely construct the water treatment system more competent with the use of CoFe 2 O 4 /OS.

“…The physical and chemical properties of NPs can be differing by their elemental composition, larger specific surface area, and composition of the coating agents ( Ahmad et al, 2013a ; Sadaf et al, 2020 ). NPs possess unique features such as mechanical properties ( Mishra et al, 2015 ; Gao et al, 2020 ), antimicrobial capabilities ( Ahmad et al, 2014a , 2015 ; Abdulla et al, 2021 ), drug delivery capacities ( Ahmad et al, 2021 ), optical properties ( Albrecht et al, 2018 ), and catalytic capabilities ( Mishra et al, 2016 ; Liu and Liu, 2017 ; Perwez et al, 2017 ; Ghosh et al, 2018a , b ) and act as artificial chaperones ( Ahmad et al, 2014b ; Ghosh et al, 2019 ).…”

In recent times, nanoparticles (NPs) have found increasing interest owing to their size, large surface areas, distinctive structures, and unique properties, making them suitable for various industrial and biomedical applications. Biogenic synthesis of NPs using microbes is a recent trend and a greener approach than physical and chemical methods of synthesis, which demand higher costs, greater energy consumption, and complex reaction conditions and ensue hazardous environmental impact. Several microorganisms are known to trap metals in situ and convert them into elemental NPs forms. They are found to accumulate inside and outside of the cell as well as in the periplasmic space. Despite the toxicity of NPs, the driving factor for the production of NPs inside microorganisms remains unelucidated. Several reports suggest that nanotization is a way of stress response and biodefense mechanism for the microbe, which involves metal excretion/accumulation across membranes, enzymatic action, efflux pump systems, binding at peptides, and precipitation. Moreover, genes also play an important role for microbial nanoparticle biosynthesis. The resistance of microbial cells to metal ions during inward and outward transportation leads to precipitation. Accordingly, it becomes pertinent to understand the interaction of the metal ions with proteins, DNA, organelles, membranes, and their subsequent cellular uptake. The elucidation of the mechanism also allows us to control the shape, size, and monodispersity of the NPs to develop large-scale production according to the required application. This article reviews different means in microbial synthesis of NPs focusing on understanding the cellular, biochemical, and molecular mechanisms of nanotization of metals.
