723 | dex-MoSe2 NS | AFM measurement was carried out to confirm the ultrathin structure of dex-MoSe2 (Fig. S1, ESI†). The height of (1–3) nm indicates that the thickness of MoSe2 is nearly one to two single layers (Fig. S1B, ESI†). The TEM images and SAED pattern of dex-MoSe2 in Fig. S2 (ESI†) reveal that the dex-MoSe2 NSs retain a lattice spacing of (0.280 ± 0.005, n = 3) nm, which matches the d-spacing of the (100) plane of 2H-MoSe2, indicating that the inherent 2H phase is still retained after exfoliation and functionalization in the dextran solution.20 The dex-MoSe2 was measured by dynamic light scattering (DLS, Fig. 1B and Fig. S3, ESI†) which shows that the average hydrodynamic size was about (62.8 ± 1.4, n = 3) nm and the zeta potential was −23.70 mV in water. |
