• of the dynamics of several proteins has been studied by Förster resonance energy transfer (FRET) [15][16][17]. This study was intended to demonstrate the potential of using dynamic light scattering (DLS) and the measurement of zeta potentials when studying the supramolecular aggregation of proteins

• , measured by dynamic light scattering (DLS): blue: MspA (1.688 × 10−5 mg·mL−1) in (5 × 10−5)× PBS; red: MspA (1.688 × 10−5 mg·mL−1) in 1× PBS. The relative experimental error in diameter has been determined to be ±8 nm. Typical polydispersities of the formed supramolecular aggregates are provided in

• remained virtually unchanged even after the MNP-SN38 was exposed to air for two weeks at room temperature. The SN38-loaded Fe/Fe3O4 magnetic nanoparticles can be easily dispersed in pH 7.4 PBS buffer (up to 30 mg/mL). The dynamic light scattering (DLS) shows that the hydrodynamic diameter of the
