“…Catalytic systems with negligible effects on the surrounding environments are desirable, but attention is usually paid to the substrate-product binomial, leaving catalysts out of the ecological concerns. Despite the increasing applications of NDs in bio-and nanomedicine [11,36], studies regarding their ecotoxic and genotoxic effects are still limited [37][38][39][40][41]. Herein, we also present a study on the cytotoxic and genotoxic evaluation of amine-functionalized nanodiamonds (ND@NH 2 ) and 2-nitro-5,10,15,20tetra(4-trifluoromethylphenyl)porphyrin covalently linked to nanodiamonds (ND@βNH-TPPpCF 3 ) using Allium cepa as a plant model, as we aimed to obtain non-fitotoxic "green" catalysts-that is, materials that will not harm the environment (even if, accidentally, not properly discarded).…”

The quest for active, yet “green” non-toxic catalysts is a continuous challenge. In this work, covalently linked hybrid porphyrin–nanodiamonds were prepared via ipso nitro substitution reaction and characterized by X-ray photoelectron spectroscopy (XPS), fluorescence spectroscopy, infrared spectroscopy (IR) and thermogravimetry-differential scanning calorimetry (TG-DSC). The amine-functionalized nanodiamonds (ND@NH2) and 2-nitro-5,10,15,20-tetra(4-trifluoromethylphenyl)porphyrin covalently linked to nanodiamonds (ND@βNH-TPPpCF3) were tested using Allium cepa as a plant model, and showed neither phytotoxicity nor cytotoxicity. The hybrid nanodiamond–copper(II)–porphyrin material ND@βNH-TPPpCF3-Cu(II) was also evaluated as a reusable catalyst in cyclohexene allylic oxidation, and displayed a remarkable turnover number (TON) value of ≈265,000, using O2 as green oxidant, in the total absence of sacrificial additives, which is the highest activity ever reported for said allylic oxidation. Additionally, ND@βNH-TPPpCF3-Cu(II) could be easily separated from the reaction mixture by centrifugation, and reused in three consecutive catalytic cycles without major loss of activity.

“…Hitherto, a study on cells, tissues, and organisms has not been reported yet, and a proof for in vivo applicability of intrinsically radiolabeled nanodiamond is still pending. In the revision of this paper, a first study of uptake of NDs thermally labeled with tritium into plants has been reported …”

Nanoparticles, especially from carbon, have great potential in biomedicine. However, prior to clinical use, biocompatibility and biodistribution of these nanoobjects have to be assessed. Currently, particle detection is mostly based on surface-bound labels, inevitably altering materials' properties by surface modification. Further obstacles include bleaching, dissociation of labels from the surface, weak emission of fluorophores due to insufficient tissue opacity or hampered light penetration or the need for specific excitation wavelengths. These characteristics greatly constrain employment of such nanoparticles to address complex analytical questions. To overcome these drawbacks, the use of intrinsic structural features of nanoobjects is highly desirable: the particle surface remains unchanged and the nanoobject exhibits its innate behavior. Thus, for sensitive detection and quantification, labels should be incorporated in the nanoparticle core, thereby avoiding cleavage and warranting unchanged surface characteristics. The incorporation of clinically approved radionuclide 32 P into the lattice of nanodiamond particles using highly defined ion implantation is described here. The properties, uptake, and biodistribution are studied in vivo, in the developing hen's egg model (hen's egg test on chorioallantoic membrane assay). It is found that 32 P labeling of diamond nanoparticles allows their reliable localization and sensitive quantification in a cost efficient, highly reliable, and safe way using available autoradiographic devices and analytical methods.

“…Composites were purified from non-bound HS and final composites were characterized by dynamic light scattering to determine particles size and zeta potential in the aqueous suspensions and liquid scintillation spectrometry to direct determination of HS surface concentration. To analyze the composites uptake and biodistribution in plants adsorption complexes of non-radioactive HS and tritium labeled nanodiamonds were obtained [1,3].…”
