Creation of nanoparticles with high monodispersity is very difficult in case of material science. Metal nanoparticle was utilised in catalysis, sensing, electronics because they are based on properties like magnetic, catalytic, medicinal and electrical properties. The metal nanoparticles were raise from silver, gold, platinum, palladium, titanium, copper, zinc etc. The metal nanoparticles act as biomedical agents and therapeutic agents for the various disorders. In the case of large‐scale usage of nanoparticles in the field like biosensors, catalysis, drug delivery and biotechnology, the most inventive method is required. The nanomaterials are usually in the range of 1–100 nm. Nanotechnology research was increasing all over the world in the twenty‐first century. The advancement in the field of life sciences and healthcare can be developed by nanotechnology, which makes the researchers work on the cellular and molecular levels. The present progression in nanomaterials welcomes new items for wide applications in different fields of studies and in particular, nanomaterials for science, hardware, transport, data innovation, physics, chemistry, medicine and instrument engineering. The findings from this review can recommend a conceivable use of biosurfactant as a source for metal nanoparticle synthesis.

This review also addressed the feasibility of biosurfactant and their benefits in the synthesis of metallic nanoparticles. In this manner, the research towards the biosurfactant has raised. Several research studies represented that the biosurfactant influences the production of nanoparticles about 2–50 nm.

This method is different from the conventional practice like physical and chemical methods. In comparison with the other technologies, biosurfactants are less toxic and exhibit higher properties. One approach investigated in this review is the use of biosurfactants to enhance the synthesis biologically. Consequently, there is need to create an eco‐friendly strategy for metal nanoparticle synthesis. The search for an optimal source with durability, stability, capacity to withstand higher environmental conditions with excellent characteristics is yet to meet. Establishing biological synthesis of nanoparticles is increasing nowadays in the field of nanotechnology.
