“…CdS QDs with an average size of 8.8 nm formed by Rhizopus stolonifer mycelial bio-mass [130]. Luminescent CdS QDs synthesized with P. ostreatus mycelium were spherical, were predominantly 4 to 5 nm in size [129], and had anticancer properties [155].…”

Oxide and chalcogenide nanoparticles have great potential for use in biomedicine, engineering, agriculture, environmental protection, and other research fields. The myco-synthesis of nanoparticles with fungal cultures, their metabolites, culture liquids, and mycelial and fruit body extracts is simple, cheap and environmentally friendly. The characteristics of nanoparticles, including their size, shape, homogeneity, stability, physical properties and biological activity, can be tuned by changing the myco-synthesis conditions. This review summarizes the data on the diversity of oxide and chalcogenide nanoparticles produced by various fungal species under different experimental conditions.

“…The synthesis of iron oxide NPs has also been performed using beet ( Beta vulgaris ) and pumpkin ( Cucurbita moschata ) extracts [ 131 ], while spice plants such as rosemary ( Rosmarinus officinalis ) and ginger ( Zingiber officinale ), respectively, have been used to produce iron- and copper-containing bimetallic NPs [ 132 , 133 ]. Not least, several angiosperms with no specific importance to humans have proved to be effective as mediators of nanoscale particle synthesis (e.g., Eichhornia crassipes , Linaria maroccana ) [ 134 , 135 ].…”

Nanotechnology is constantly expanding, with nanomaterials being more and more used in common commercial products that define our modern life. Among all types of nanomaterials, nanoparticles (NPs) occupy an important place, considering the great amount that is produced nowadays and the diversity of their applications. Conventional techniques applied to synthesize NPs have some issues that impede them from being appreciated as safe for the environment and health. The alternative to these might be the use of living organisms or biological extracts that can be involved in the green approach synthesis of NPs, a process that is free of harmful chemicals, cost-effective and a low energy consumer. Several factors, including biological reducing agent concentration, initial precursor salt concentration, agitation, reaction time, pH, temperature and light, can influence the characteristics of biologically synthesized NPs. The interdependence between these reaction parameters was not explored, being the main impediment in the implementation of the biological method on an industrial scale. Our aim is to present a brief review that focuses on the current knowledge regarding how the aforementioned factors can control the size and shape of green-synthesized NPs. We also provide an overview of the biomolecules that were found to be suitable for NP synthesis. This work is meant to be a support for researchers who intend to develop new green approaches for the synthesis of NPs.

“…The Cd-based QDs toxicity mechanism triggers the typical response of cells subjected to oxidative stress from both ROS and cadmium ions [185]. Garmanchuk et al developed alternative approach for extracellular synthesis of CdS QDs using Escherichia coli bacteria and they measured the viability of HeLa cells after exposed to CdS QDs [165]. Trough the MTT and flow cytometry assay, they found that CdS QDs can inhibit cell growth and cause cell apoptosis and the decrease of cell adhesion.…”

Recent advances in inorganic nanomaterial-based theranostics enabled imaging-guided molecular targeting and drug delivery, and various combinations of theranostic systems. The term “theranostics” is defined as diagnosis processed with therapy simultaneously with a specific connection between therapy and diagnosis. The inorganic nanomaterials, representatively carbon, metal, ceramic, and semiconductor-based nanomaterials, exhibit their unique characteristics to be used in theranostic applications. However, the unveiled human biosafety of nanomaterials for clinical use has become a major concern. Therefore, in this review, we compiled recent research on in vitro and in vivo biosafety of inorganic nanomaterials in various theranostic applications, along with a discussion of how the particle formulation, size, surface functionalization, test species, and test condition affect biocompatibility. Furthermore, the progress and challenges of the development of biocompatible inorganic nanomaterials for theranostic applications were discussed. In conclusion, with appropriate precautions on the biosafe condition to be administered, inorganic nanomaterials can be proposed to have excellent potential in the future theranostic application.
