“…It is a comparatively new branch of nanoscience. Algae are used for the synthesis of nanoparticles as they have a high potential to accumulate metal, are easy to handle and cultivate, can grow at low temperatures, and are less toxic to the environment [ 74 ]. Chlorophyceae , Phaeophyceae , Cyanophyceae , and Rhodophyceae are the most common types of algae that are used for the synthesis of silver nanoparticles [ 73 ].…”

Background Nanoparticle synthesis is a very interesting area of research currently due to the wide applications of nanoparticles. The nanoparticles have a diameter ranging between 1 and 100 nm and they are used in different fields like electronics, pharmaceuticals, cosmetics, biotechnology, medicines, etc. Main body of the abstract Nanoparticles have gained the interest of researchers due to their large surface-to-volume ratio and their capability to interact effectively with other particles. Several different methods can be used for the production of silver nanoparticles (AgNPs) including chemical, physical, and biological. Out of all the methods, the biological method is considered the cleanest and safest as no toxic chemicals are used in the process. The biological method includes the use of bacteria, fungi, algae, and plant extract for the synthesis. Algal synthesis of AgNPs is especially interesting because of the high capacity of the algae to take in metals and reduce metal ions. Algae is a widely distributed organism and its availability is abundant; an added advantage is their growth under laboratory conditions. These organisms can help in large-scale production at a low cost. Short conclusion This review article explains the different factors that should be considered for the effective synthesis of AgNPs using algae. Capping agents also affect the stability of nanoparticles. It also sheds light on the importance of capping agents in the synthesis of AgNPs. Alga-mediated synthesis of AgNPs along with the use of different capping agents can help in modulating the stability and size of the nanoparticles, thereby improving its cost-effectiveness and environment-friendly production.

“…Recently, a drastic shift has been noticed in this field, and now algae are looked at as one of the green resources for the synthesis of various nanoparticles. Algae are a rich source of proteins, peptides, secondary metabolites, and pigments, which make them an attractive nanofactory (Negi and Singh, 2018). Working with algae is advantageous as they are fast-growing, can grow in a simple, inexpensive medium, offer ease of scale-up, and are easy to culture and harvest (Fabris et al, 2020).…”

The biomedical properties of nanoparticles have been the area of focus for contemporary science; however, there are issues concerning their long-term toxicities. Recent trends in nanoparticle fabrication and surface manipulation, the use of distinctive biogenic capping agents, have allowed the preparation of nontoxic, surface-functionalized, and monodispersed nanoparticles for medical applications. These capping agents act as stabilizers or binding molecules that prevent agglomeration and steric hindrance, alter the biological activity and surface chemistry, and stabilize the interaction of nanoparticles within the preparation medium. Explicit features of nanoparticles are majorly ascribed to the capping present on their surface. The present review article is an attempt to compile distinctive biological capping agents deployed in the synthesis of metal nanoparticles along with the medical applications of these capped nanoparticles. First, this innovative review highlights the various biogenic capping agents, including biomolecules and biological extracts of plants and microorganisms. Next, the therapeutic applications of capped nanoparticles and the effect of biomolecules on the efficiency of the nanoparticles have been expounded. Finally, challenges and future directions on the use of biological capping agents have been concluded. The goal of the present review article is to provide a comprehensive report to researchers who are looking for alternative biological capping agents for the green synthesis of important metallic nanoparticles.

“…The different types of freshwater and marine algae are being used for the synthesis of nanoparticles, Caulerpa racemosa , Hypnea musciformis , Padina pavonica (Linn. ), Sargassum muticum , Spirulina platensis , and Turbinaria conoides (Negi & Singh, 2018). Marine algae have more importance in the synthesis because of their high absorbing capacity of metals from the ocean or sea (Hussain, Shah, Shuaib, Bahadur, & Muhammad, 2019).…”

The widespread use of silver nanoparticles (AgNPs) results in the unintentional release into the water body. Therefore, understanding of the potentially harmful impacts of AgNPs and Ag‐salt on aquatic animals is a need of time. This study was design to analyze the oxidative stress and histopathological damages in Cyprinus carpio. The synthesis of AgNPs from Halymenia porphyraeformis and by reduction of chemical was done. Nanoparticles were characterized with UV–Visible spectroscopy, SEM, XRD, and FTIR analysis. The comparative toxicological effect of chemically synthesized silver nanoparticles (Ch‐AgNPs), green silver nanoparticles (Gr‐AgNPs), and Ag‐salt on C. carpio was analyzed. For oxidative stress analysis, different tests Lipid peroxidation (LPO), catalase, glutathione reduction (GST), and glutathione S‐transferase (GST) were performed. The highest LPO 245.168 ± 0.034 was recorded in Ch‐AgNPs‐treated gills and the lowest 56.4532 ± 0.02 was found in Gr‐AgNPs‐treated liver. Maximum GSH 56.4065 ± 0.13 was observed in Gr‐AgNPs liver and minimum 40.781 ± 0.54 was recorded in Ag‐salt gills. The maximum quantity of catalase 68.0162 ± 0.09 was noted in the Ag‐salt‐treated liver and the minimum was calculated 17.3665 ± 0.01 in the liver of Ch‐AgNPs and highest values of GST 765.829 ± 0.11 were recorded in gills of Gr‐AgNPs and lowest 633.08 ± 0.26 in the liver of Ch‐AgNPs‐treated fish. In conclusion, maximum destruction was found in the gills and liver of the fish treated with chemical and green AgNPs followed by Ag‐salt as compared to control. The adverse effects of AgNPs and Ag‐salt were probably related to the oxidative stress in the fish that lead to histopathological damage of its vital organs.
