Abstract
Nanoparticles are gaining importance as versatile materials showing novel or advanced characteristics as compared to larger particles. Synthesis of nanoparticles is being done via chemical and physical methods, and it restricts the potential applications in fields like biomedical and agriculture. Among the biological resources, algae have a tremendous role in bioconversion to different particles. Several applications of metal nanoparticles and nanomaterials have emerged in recent past. Among these, gold nanoparticles have their significant role owing to their potential use in nanoelectronics, deoxyribonucleic acid labeling and biosensor development. This review paper focuses on the use of algae for gold nanoparticle synthesis and on its potential and future prospects as well. It can be concluded that various factors like different algae, pH, protocol, time and pigments affect the shape, structure, size and yield of gold nanoparticles synthesized by the algae. Further, potential applications of nanoparticles synthesized by different algae have been reported.
