“…Conventional physical and chemical methods tend to be energy-intensive [15] , with chemical processes particularly requiring solvent use, which contributes to the environmental impact as well as overall cost [16] , [17] . In contrast, biological or green syntheses are designed to be inexpensive and eco-friendly, using agents obtained from natural sources (plants [18] , bacteria [19] , algae [20] , or fungi [21] ) for the production of AuNPs. Phytosynthesis, which utilizes plant biomasses or extracts that serve to act as reducing agents for AuNPs, is of particular interest [22] , [23] .…”

“…Plasmonic NPs, such as Au and Ag, have been also produced using microorganisms both intracellularly and extracellularly [ 125 , 126 , 127 ]. Several bacteria, such as Caldicellulosiruptor changbaiensis , Shewanella loihica , Micrococcus yunnanensis , Stenotrophomonas maltophilia , Actinobacterspp Rhodopseudomonas , P. aeruginosa , Bacillus , Escherichia coli and Klebsiella pneumoniae [ 104 , 105 , 106 , 107 , 108 , 109 , 110 , 111 , 112 , 113 ], fungi, among them Alternaria alternate , Fusarium oxysporum , T. koningii , Hormoconis resinae , Aureobasidium pullulans , Fusarium , Phanerochaete Chrysosporium and Botrytis cinerea [ 114 , 115 , 116 , 117 , 118 , 119 , 128 ], and algae [ 120 , 121 ] have been investigated as a Au-nanoparticle-reducing agent. To give some examples, recently Jafari and co-authors [ 106 ] used the Micrococcus yunnanensis J2 strain to biosynthesize Au NPs, which possessed anticancer activity towards six cancer cell lines and an antibacterial effect against both Gram-positive and negative strains.…”

In recent years, nanotechnologies have attracted considerable interest, especially in the biomedical field. Among the most investigated particles, magnetic based on iron oxides and Au nanoparticles gained huge interest for their magnetic and plasmonic properties, respectively. These nanoparticles are usually produced starting from processes and reagents that can be the cause of potential human health and environmental concerns. For this reason, there is a need to develop simple, green, low-cost, and non-toxic synthesis methods and reagents. This review aims at providing an overview of the most recently developed processes to produce iron oxide magnetic nanoparticles, Au nanoparticles, and their magneto-plasmonic heterostructures using eco-friendly approaches, focusing the attention on the microorganisms and plant-assisted syntheses and showing the first results of the development of magneto-plasmonic heterostructures.

Nanotechnology is a rapidly evolving discipline as it has a wide variety of applications in several fields. They have been synthesized in a variety of ways. Traditional processes such as chemical and physical synthesis have limits, whether in the form of chemical contamination during synthesis operations or in subsequent applications and usage of more energy. Over the last decade, research has focused on establishing easy, nontoxic, clean, cost-effective, and environmentally friendly techniques for nanoparticle production. To achieve this goal, biological synthesis was created to close this gap. Biosynthesis of nanoparticles is a one-step process, and it is ecofriendly in nature. The metabolic activities of biological agents convert dissolved metal ions into nanometals. For biosynthesis of metal nanoparticles, various biological agents like plants, fungus, and bacteria are utilized. In this review paper, the aim is to provide a summary of contemporary research on the biosynthesis of gold nanoparticles and their applications in various domains have been discussed.
