“…In many bioinspired NMs, advanced nanofabrication techniques are used to modulate their structures and obtain specific functions. For example, the rapid color change observed in chameleons when fighting or during courtship is mainly explained by the lattice adjustment of guanine nanocrystals in iridophore cells [48]. The photonic structure of chameleon iridophores can be mimicked by incorporating silica nanocrystals into mechanochromic elastomer sensors as non-dense packed crystals.…”

Nanomaterials are materials with one or more nanoscale dimensions (internal or external) (i.e., 1 to 100 nm). The nanomaterial shape, size, porosity, surface chemistry, and composition are controlled at the nanoscale, and this offers interesting properties compared with bulk materials. This review describes how nanomaterials are classified, their fabrication, functionalization techniques, and growth-controlled mechanisms. First, the history of nanomaterials is summarized and then the different classification methods, based on their dimensionality (0–3D), composition (carbon, inorganic, organic, and hybrids), origin (natural, incidental, engineered, bioinspired), crystal phase (single phase, multiphase), and dispersion state (dispersed or aggregated), are presented. Then, the synthesis methods are discussed and classified in function of the starting material (bottom-up and top-down), reaction phase (gas, plasma, liquid, and solid), and nature of the dispersing forces (mechanical, physical, chemical, physicochemical, and biological). Finally, the challenges in synthesizing nanomaterials for research and commercial use are highlighted.

Biosynthesis of antioxidant nanoparticles using plant extracts is a simple, rapid, environmentally friendly, and cost-effective approach. In this study, in vitro antioxidant copper mixed oxide nanoparticles (CuO/Cu2O) were prepared from the alcoholic extract of Phoenix Dactylifera L. and different aqueous concentrations of CuSO4·5H2O. The composition, crystallinity, morphology, and particle size of CuO/Cu2O NPs were tuned by increasing the CuSO4·5H2O concentration from 4 to 10 mM. Ultraviolet–visible (UV–Vis) and Fourier-transform infrared (FTIR) spectroscopy confirmed the reduction of CuSO4·5H2O and the formation of the CuO/Cu2O NPs. X-ray diffraction (XRD) confirmed the crystalline nature of the CuO/Cu2O NPs with a crystallite size varying from 18 to 35 nm. Scanning electron micrographs (SEM) showed that the CuO/Cu2O NPs have a spherical morphology with particle sizes ranging from 25 to 100 nm. The best antioxidant CuO/Cu2O NPs have a phase ratio of about 1:1 CuO/Cu2O with a half-maximal inhibitory concentration (IC50) of 0.39 mg/ml, an iron-containing reducing antioxidant power (FRAP) of 432 mg EFeSO4/100 mg NPs, and a total antioxidant capacity (TAC) of 65 mg EAA/gNPs. The results suggest that the synthesized CuO/Cu2O NPs are excellent antioxidants for therapeutic applications. Graphical abstract
