In green biological synthesis, metal nanoparticles are produced by plants or microorganisms. Since it is ecologically friendly, economically viable and sustainable, this method is preferable to other traditional ones. For their continuous groundbreaking advancements and myriad physiochemical and biological benefits, nanotechnologies have influenced various aspects of scientific fields. Metal nanoparticles (MNPs) are the field anchor for their outstanding optical, electrical and chemical capabilities that outperform their regular-sized counterparts. This review discusses the most current biosynthesized metal nanoparticles synthesized by various organisms and their biological applications along with the key elements involved in MNP green synthesis. The review is displayed in a manner that will impart assertiveness, help the researchers to open questions, and highlight many points for conducting future research.

“…On the other hand, cyanobacteria and microalgae are gaining interest in green synthesis due to their heavy metal hyperaccumulation, considerably higher CO 2 sequestration rate, lack of toxic byproducts, use of biomolecules (pigments and enzymes) as capping and reducing agents, and also for their low energy input. Since algae are excellent phytonutrients, proteins, pigments, and other nutrient sources, the synthesis process has improved over time, which serves as a significant bio-manufacturer for nanoparticle production [43].…”

“…As a natural capping and reducing agent, the algae extract acts as a living cell factory for synthesizing NPs [45,46]. Additionally, due to the secondary metabolites present in algae (plant acids, flavonoids, phenolics, terpenoids, alkaloids, and glycosides) that contain numerous biological effects, the developed materials could be used as nutrition, stimulants, preservatives, antioxidants, insecticides, anticancer, antiviral, and antibacterial agents [43].…”

In recent years, interest in nanotechnology has increased exponentially due to enhanced progress and technological innovation. In tissue engineering, the development of metallic nanoparticles has been amplified, especially due to their antibacterial properties. Another important characteristic of metal NPs is that they enable high control over the features of the developed scaffolds (optimizing their mechanical strength and offering the controlled release of bioactive agents). Currently, the main concern related to the method of synthesis of metal oxide NPs is the environmental impact. The physical and chemical synthesis uses toxic agents that could generate hazards or exert carcinogenicity/environmental toxicity. Therefore, a greener, cleaner, and more reliable approach is needed. Green synthetic has come as a solution to counter the aforementioned limitations. Nowadays, green synthesis is preferred because it leads to the prevention/minimization of waste, the reduction of derivatives/pollution, and the use of non-toxic (safer) solvents. This method not only uses biomass sources as reducing agents for metal salts. The biomolecules also cover the synthesized NPs or act as in situ capping and reducing agents. Further, their involvement in the formation process reduces toxicity, prevents nanoparticle agglomeration, and improves the antimicrobial activity of the nanomaterial, leading to a possible synergistic effect. This study aims to provide a comprehensive review of the green synthesis of metal and metal oxide nanoparticles, from the synthesis routes, selected solvents, and parameters to their latest application in the biomedical field.

Antibiotic resistance against infections caused by microbes has emerged as a global challenge resulting in longer hospitalizations and higher medical cost and mortality. The excessive use of antibiotics has led to the swift progression of antibiotic resistance in bacterial strains. Metallic and metal oxide (M/MO) nanoparticles (NPs) have the potential to provide a pertinent alternative to antibiotics as they interact with the critical cellular organelles and biomolecules such as DNA, enzymes, ribosomes, and lysosomes. This affects the permeability of the cell membrane causing oxidative stress, gene expression, protein activation, and enzyme activation restricting the habitat of microbes. Further, NPs simultaneously target multiple biomolecules at once making them an efficient antibacterial agent against which microbes are unable to develop resistance easily, although the toxicity associated with the M/MO NPs still remains a key challenge for clinical uses. Green synthesis provides an efficient solution to reduce the toxic effects associated with these NPs as it does not use harsh chemicals and environment for the synthesis of NPs. In this work, we have provided a comprehensive review of the green synthesis of M/MO NPs using plants (roots, seeds, barks, flowers) and microbes (bacteria, fungi, algae). The yield of the NPs achieved from the green synthesis is lower than that of conventional methods and significant advancements have been made recently which are delineated in this review for different M/ MO NPs. Further, the mechanism of NP interaction with the microbes and their different antimicrobial applications have been discussed in detailed. The present review aims to provide a critical overview of the current state of the large-scale synthesis of the M/ MO NPs as well as their different antimicrobial activities.
