“…The size of synthetized nanoparticles depends on microalgal strain and metal type used, but place of synthesis, initial metal loading, light and temperature are also crucial factors influencing formation of nanoparticles. Additionally, synthesis of Cd nanoparticles in a form of CdS [ 177 ] or Ni nanoparticles as a product of reduction of other nanoparticles (NiO) [ 75 ], was also reported. Besides nanoparticles, biosynthesis of nanoneedles by microalgae also occurs; such nanoneedles, composed of zinc and phosphorous, were detected in Scenedesmus obliquus cells as a result of exposure to high Zn concentration [ 178 ].…”

Microalgae are a source of numerous compounds that can be used in many branches of industry. Synthesis of such compounds in microalgal cells can be amplified under stress conditions. Exposure to various metals can be one of methods applied to induce cell stress and synthesis of target products in microalgae cultures. In this review, the potential of producing diverse biocompounds (pigments, lipids, exopolymers, peptides, phytohormones, arsenoorganics, nanoparticles) from microalgae cultures upon exposure to various metals, is evaluated. Additionally, different methods to alter microalgae response towards metals and metal stress are described. Finally, possibilities to sustain high growth rates and productivity of microalgal cultures in the presence of metals are discussed.

“…Two isotherm models, the Langmuir and Freundlich models, are widely used to fit the adsorption isotherm experimental data [35,36]. In general, the studies of adsorption kinetic and isotherm models show that the adsorption of algae to NPs is best fitted to a pseudo-second order kinetic model and Langmuir isotherm model [35,37,38]. The initial concentration of NPs in water influenced the adsorption of algae to NPs.…”

With the rapid development of nanotechnology and widespread use of nanoproducts, the ecotoxicity of nanoparticles (NPs) and their potential hazards to the environment have aroused great concern. Nanoparticles have increasingly been released into aquatic environments through various means, accumulating in aquatic organisms through food chains and leading to toxic effects on aquatic organisms. Nanoparticles are mainly classified into nano-metal, nano-oxide, carbon nanomaterials and quantum dots according to their components. Different NPs may have different levels of toxicity and effects on various aquatic organisms. In this paper, algae are used as model organisms to review the adsorption and distribution of NPs to algal cells, as well as the ecotoxicity of NPs on algae and fate in a water environment, systematically. Meanwhile, the toxic effects of NPs on algae are discussed with emphasis on three aspect effects on the cell membrane, cell metabolism and the photosynthesis system. Furthermore, suggestions and prospects are provided for future studies in this area.

“…It is well known that the pH controls the adsorption of metal ions by protonation and deprotonation of metal binding sites [ 91 ]. However, the ion adsorption process may vary between algal species due to differences in the cell surface composition.…”

Bionanotechnology, the use of biological resources to produce novel, valuable nanomaterials, has witnessed tremendous developments over the past two decades. This eco-friendly and sustainable approach enables the synthesis of numerous, diverse types of useful nanomaterials for many medical, commercial, and scientific applications. Countless reviews describing the biosynthesis of nanomaterials have been published. However, to the best of our knowledge, no review has been exclusively focused on the in vivo biosynthesis of inorganic nanomaterials. Therefore, the present review is dedicated to filling this gap by describing the many different facets of the in vivo biosynthesis of nanoparticles (NPs) using living eukaryotic cells and organisms—more specifically, live plants and living biomass of several species of microalgae, yeast, fungus, mammalian cells, and animals. It also highlights the strengths and weaknesses of the synthesis methodologies and the NP characteristics, bio-applications, and proposed synthesis mechanisms. This comprehensive review also brings attention to enabling a better understanding between the living organisms themselves and the synthesis conditions that allow their exploitation as nanobiotechnological production platforms as these might serve as a robust resource to boost and expand the bio-production and use of desirable, functional inorganic nanomaterials.
