“…From Figure a, F101 can be seen to exhibit a smooth rhombohedral octahedron shape (ca. 0.5 μm in diameter), in accordance with results reported in the literature . Such a shape was largely retained in the F101@MoS 2 composite except that the surface became markedly roughened and decorated with a number of petals that are most likely MoS 2 nanosheets (Figure b).…”

“…Further structural insights are obtained from Raman spectroscopic measurements (Figure b). F101 (black curve) can be seen to exhibit two broad bands at 1396 and 1584 cm –1 , arising from sp 2 carbon virbations . The MoS 2 shows three characteristic peaks at 280.8, 376.5, and 404.7 cm –1 due to the E 1g , E 2g1 , and A 1g longitudinal phonon modes of 2H-MoS 2 (red curve), along with three additional peaks at 195.4, 235.6, and 335.7 cm –1 characteristic of the phonon modes of 1T-MoS 2 . , These vibrational features were all well-defined in F101@MoS 2 and F101@MoS 2 /ZnO.…”

“…In addition, to detect OTA, an iron-based metal-organic structure (NH 2 -MIL-101) was mixed with various doses of cobalt phthalocyanine nanoparticles (CoPc) to prepare a range of NH 2 -MIL-101@CoPc nanocomposites ( Figure 6 A). The aptasensor based on (NH 2 /MIL-101(Fe)@CoPc 6:1) showed a performance for sensing OTA in watermelon and wine with a low detection limit (LOD) of 0.063 × 10 –9 mg/L and 1.0 × 10 −10 to 1.0 × 10 −4 mg/L linearity range [ 68 ]. The construction of a sensing assay based on NH 2 -MIL-101@CoPc to detect OTA is schematically shown in Figure 6 B.…”
