Abstract
AbstractThe world is rapidly shifting toward waste minimization and processes that are eco-friendly, sustainable, and protects environment. The green synthesis of nanoparticle using principles of green chemistry fits perfectly in the current scenario. The use of biological components, compounds, cells, extracts, and metabolites as reducing and capping agent for synthesis of nanoparticle constitutes the core of green nanotechnology. Recently, algae, both macro- and microalgae, have been explored for rapid synthesis of nanoparticles with greater control over size and shape. Marine and freshwater algae are rich sources of terpenoids, bioflavonoids, aliphatic amines, sulfated polysaccharides, and secondary metabolites which help in synthesis of nanoparticles with distinct size, shape, and bioactivity. Algae are mostly used for synthesis of metallic particles because the algal constituents can rapidly donate their charge leading to reduction in metals to their elemental form. Therefore, they present an ideal platform for rapid and large-scale production of green nanoparticle. This chapter gives an account of the various algae, mode of synthesis, process parameters, and factors affecting synthesis, mechanism, and applications of metallic nanoparticles. The applications of metallic nanoparticle are discussed in relation with biomedical and biosensing applications.KeywordsAlgaeApplicationsGreen synthesisNanoparticles
