Stability of alginic acid (AA)-dispersed multiwall carbon nanotubes (CNT) CNT-1, CNT-2, and CNT-3, graphene nanoplatelets (GNP) GNP-1 and GNP-2, boron nitride nanotubes (BNNT), and hexagonal boron nitride flakes (hBN) in (a,b) Dryl’s medium and (c,d) half-strength 21C medium over one day, as evidenced by the time course of (a,c) the relative optical density at 600 nm (OD₆₀₀, as a proxy for dispersed particle concentration) as compared to the OD₆₀₀ at time 0 of the experiment, and (b,d) hydrodynamic diameter as measured by dynamic light scattering (DLS). The dispersion and dilution protocol followed that of Scheme 1. Data bars are mean ± SE (n = 3). Note that some error bars (a,c) do not appear on the graph due to their small values.
