Electrophoretic mobility, ζ-potential, and charge density of PAMAM nanoparticles and NT4 molecules

PBS concentration (M)	PAMAM (G6)			NT4
μe (μm•cm [Vs]−1)	ζl (mV)	Qc* (e)	μe (μm•cm [Vs]−1)	ζp (mV)	Qc* (e)	Qc** (e)
0.15, pH 7.4	1.16	22.2	5.8	−0.47	−8.2	−1.0	−1.7

Notes: *Calculated from Lorenz model; **calculated from $2\pi d_H\frac{1+\kappa d_H}{f\left(\kappa d_H\right)}{\mu }_e$ (Henry model).

Abbreviation: PAMAM, polyamidoamine.
