Nanotechnology's application in biological domains has gotten a lot of interest recently, with applications in fields including cancer therapy, medication delivery, biosensors, antioxidants, antimicrobials, agriculture, and so on. The most typically manufactured nanoparticles are gold, silver, iron, copper, nickel, and selenium, which will be the focus of this review due to their excellent biological activity. Green synthesis of SeNPs is a better alternative for the environment than previous approaches. Selenium nanoparticles of various shapes and sizes can be created using numerous raw materials and processes, each of which imparts unique properties to the nanoparticles generated. Plant materials with proven bio-active qualities, such as Aloe vera leaves, citrus fruits, and cinnamon bark, were shown to be ideal for green synthesis of selenium nanoparticles. The benefits of selenium include its natural availability, minimal toxicity (in nanoparticle form), and antibacterial and antioxidant effects. Even though the specific mechanism of action is unknown, the combined effect of the plant's bioactive characteristics, selenium's antioxidant properties, and heightened reactivity in nano-particle form has done wonders against some of the most deadly human infections. With microbial pathogens becoming increasingly resistant to the present antibiotic arsenal, these cutting-edge methods are critical in our fight against microbial diseases. The green synthesis of Selenium nanoparticles utilising various plant extracts, as well as their characterisation methodologies and antibacterial activity against a variety of bacteria and fungi, are reviewed in this paper.
