Product# ND-50

Size: monodispersion

All our nanodiamond samples are fully via Dynamic Light Scattering (DLS, Fig. 2) to determine size, polydispersity index (PDI) and zeta potential (ZP).


Figure 1. Dynamic light scattering (DLS) analysis of Product#ND-80. DLS is used to determine the polydispersivity index (PDI) and Zeta Potential (ZP) of each batch.

Size: 47.0±6.8 nm

Zeta potential (in water): -42.0±12.8 mV

Polydisperdsity index: 0.145

Surface analysis

We carry out Raman and FTIR spectroscopy (Figs. 2, 3).
