“…Blue-green algae (Cyanophyta) contain three orders: Chroococcales, Chamaesiphonales, and Hormogoneales; of which Chroococcales separates into two families-Chroococcaceae and Entophysalidaceae. 258,259 These two families can be distinguished from their ability to form colonies in their natural habitat, and are considered photoautotrophic, unicellular bacteria. 258,259 Blue-green algae have been widely used to generate a wide range of NPs, as shown in Table 5.…”

The necessity to engineer sustainable nanomaterials for the environment and human health has recently increased. Due to their abundance, fast growth, easy cultivation, biocompatibility and richness of secondary metabolites, algae are valuable biological source for the green synthesis of nanoparticles (NPs). The aim of this review is to demonstrate the feasibility of using algal-based NPs for cancer treatment. Blue-green, brown, red and green micro-and macro-algae are the most commonly participating algae in the green synthesis of NPs. In this process, many algal bioactive compounds, such as proteins, carbohydrates, lipids, alkaloids, flavonoids and phenols, can catalyze the reduction of metal ions to NPs. In addition, many driving factors, including pH, temperature, duration, static conditions and substrate concentration, are involved to facilitate the green synthesis of algal-based NPs. Here, the biosynthesis, mechanisms and applications of algal-synthesized NPs in cancer therapy have been critically discussed. We also reviewed the effective role of algal synthesized NPs as anticancer treatment against human breast, colon and lung cancers and carcinoma.

“…Timiriazev Institute for Plant Physiology of the Russian Academy of Sciences was used. The cultivation conditions for S. platensis cells in standard water-salt nutrient medium are described elsewhere [13,14]. After 5-day cultivation, cells of S. platensis were separated from the culture broth by centrifugation (12,000 g) for 20 min, and then the biomass was washed twice with sterile distilled water.…”

“…In our earlier investigations, S. platensis was used as a matrix for the development of new pharmaceutical substances [13][14][15][16]. The elemental content of the initial biomass of Spirulina was studied using the neutron activation analysis; it was shown that the concentrations of some toxic elements in the biomass of S. platensis do not exceed permissible levels [14].…”

Abstract:The synthesis of gold and silver nanoparticles by the blue-green algae Spirulina platensis for medical purposes was studied. A complex of optical and analytical methods was used in order to characterize produced nanoparticles. It was shown that the extracellular formation of metal nanoparticles of spherical shape with sizes in the range between 8 and 40 nm (the average size of 20-30 nm) takes place. The characteristics of gold and silver nanoparticles in the Spirulina biomass were compared. The role of biosorption processes in the synthesis of nanoparticles was estimated by using equilibrium dialysis. A positive influence of sonication on the process of microbial synthesis and yield of nanoparticles were demonstrated. The neutron activation analysis and the atomic absorption spectrometry were applied for characterizing the dynamics of gold and silver nanoparticles formation in the Spirulina platensis biomass. The neutron activation analysis was used for studying the elemental content of the Spirulina platensis biomass.
