“…It should be noted that the synthesis method of Ni 3 S 2 is the same as the CoNi 2 S 4 with some minor modifications. However, the fingerprints of the Ni 3 S 2 are 2217 cm −1 , 2108 cm −1 , 1870 cm −1 , and 618 cm −1 , which have differences with the present spectrum 42 – 44 . The synthesized nanocomposite has minimal covalent interactions with the H 2 TMP; if the cobalt had any covalent interactions with the porphyrin, some major and sharp peaks at 1099 cm −1 , 920 cm −1 , and also 802 cm −1 should be observed 45 – 47 .…”

Herein, in a one-pot method, the reduced graphene oxide layers with the assistance of multiwalled carbon nanotubes were decorated to provide a suitable space for the in situ growth of CoNi2S4, and the porphyrins were incorporated into the layers as well to increase the sensitivity of the prepared nanostructure. The prepared nanocomposite can establish π–π interactions between the genetic material and on the surface of porphyrin rings. Also, hydrogen bonds between genetic domains and the porphyrin’ nitrogen and the surface hydroxyl groups are probable. Furthermore, the potential donor–acceptor relationship between the d7 transition metal, cobalt, and the genetic material provides a suitable way to increase the interaction and gene loading , and transfections. The reason for this phenomenon was optimized to increase the EGFP by up to 17.9%. Furthermore, the sensing ability of the nanocomposite towards H2O2 was investigated. In this regard, the limit of detection of the H2O2 obtained 10 µM. Also, the in situ biosensing ability in the HEK-293 and PC12 cell lines was evaluated by the addition of PMA. The nanocomposite showed the ability to detect the released H2O2 after adding the minimum amount of 120 ng/mL of the PMA.

“…48-1548), and ZnO (no. 36-1541), respectively. − Besides, all the calcined production displayed prominent peaks and an increased peak width in XRD patterns suggesting that the chromate nanoparticles fabricated by the sol–gel approach possessed rather small crystallite sizes. Furthermore, the crystallite sizes of these nanochromates were calculated from their corresponding XRD peak broadening of the most intense diffraction peak (3 1 1) using the Scherrer formula, D = K λ/βcosθ, and the average crystallite sizes of CoCr 2 O 4 , NiCr 2 O 4 , CuCr 2 O 4 , and ZnCr 2 O 4 nanoparticles were determined as 22.0, 23.4, 23.4, and 22.7 nm, respectively.…”

The chromate nanoparticles such as CoCr2O4, NiCr2O4, CuCr2O4, and ZnCr2O4 were prepared by a modified sol–gel method. The structural and morphological properties of the chromate nanoparticles were characterized by X-ray diffraction (XRD) and a scanning electron microscope (SEM). The catalytic effects of chromates on the thermal decomposition of fine ammonium perchlorate (FAP) and hexanitrohexaazaisowurtzitane (CL-20) were studied by the TG-DTG measurements. Results show that the addition of CoCr2O4, NiCr2O4, CuCr2O4, and ZnCr2O4 nanoparticles makes the activation energies for the thermal decomposition of FAP decrease by 93.9, 94.0, 83.1, and 67.0 kJ·mol–1, and the thermal decomposition temperatures decrease by 45.0, 24.9, 57.7, and 38.8 K respectively. On the other hand, a similar trend exists in the case of the thermal decomposition of CL-20. Therefore, the addition of nanochromates shows high catalytic efficiency on the thermal decomposition of both FAP and CL-20 components, which would be beneficial to promote the burning rate of propellants containing FAP and CL-20 components.

“…Based on Figure a, the fingerprint absorption peaks for CoNi 2 S 4 , which are 3450, 1630, 1370, 901  , and 610 cm –1 , match up with the stretching and bending vibrations of the water compartment (O–H) on the surface of the Co (Co–O–H), C–O–C vibrations, N–CS, and CS vibrations of thiourea, respectively, ,− thus affirming the successful in situ and one-pot synthesis of the nanocomposite along with CoNi 2 S 4 . It should be noted that the synthesis method for Ni 3 S 2 is the same as that of CoNi 2 S 4 with some minor modifications; however, the fingerprints of the Ni 3 S 2 are 2217, 2108, 1870  , and 618 cm –1 , which clearly differ from the present spectrum. − By addition of DOX to the synthesized nanocomposite, three new peaks were represented at 810, 1120  , and 1730 cm –1 , which correspond to the stretching bands of DOX on the surface of the carbon-based nanocomposite . It should be noted that the synthesized nanocomposite has not any covalent interactions with the DOX due to the absence of the peaks at around 1099, 920  , and also 802 cm –1 , which are indicative of the covalent bonding between the cobalt or zinc and the DOX structure.…”

Hybrid bioactive inorganic−organic carbon-based nanocomposites of reduced graphene oxide (rGO) nanosheets enlarged with multi-walled carbon nanotubes (MWCNTs) were decorated to provide a suitable space for in situ growth of CoNi 2 S 4 and green-synthesized ZnO nanoparticles. The ensuing nanocarrier supplied π−π interactions between the DOX drug and a stabilizing agent derived from leaf extracts on the surface of ZnO nanoparticles and hydrogen bonds; gene delivery of (p)CRISPR was also facilitated by chitosan and alginate renewable macromolecules. Also, these polymers can inhibit the potential interactions between the inorganic parts and cellular membranes to reduce the potential cytotoxicity. Nanocomposite/nanocarrier analyses and sustained DOX delivery (cytotoxicity analyses on HEK-293, PC12, HepG2, and HeLa cell lines after 24, 48, and 72 h) were indicative of an acceptable cell viability of up to 91.4 and 78.8% after 48 at low and high concentrations of 0.1 and 10 μg/mL, respectively. The MTT results indicate that by addition of DOX to the nanostructures, the relative cell viability increased after 72 h of treatment; since the inorganic compartments, specifically CoNi 2 S 4 , are toxic, this is a promising route to increase the bioavailability of the nanocarrier before reaching the targeted cells. Nanosystems were tagged with (p)CRISPR for co-transfer of the drug/genes, where confocal laser scanning microscopy (CLSM) pictures of the 4′,6-diamidino-2phenylindole (DAPI) were indicative of appropriate localization of DOX into the nanostructure with effective cell and drug delivery at varied pH. Also, the intrinsic toxicity of CoNi 2 S 4 does not affect the morphology of the cells, which is a breakthrough. Furthermore, the CLSM images of the HEK-293 and HeLa cell displayed effective transport of (p)CRISPR into the cells with an enhanced green fluorescent protein (EGFP) of up to 8.3% for the HEK-293 cell line and 21.4% for the HeLa cell line, a record. Additionally, the specific morphology of the nanosystems before and after the drug/gene transport events, via images by TEM and FESEM, revealed an intact morphology for these biopolymers and their complete degradation after long-time usage.
