Characterisation by dynamic light scattering (DLS) of stability of SLN-A (a) particle size; (b) zeta potential at −20 °C, 4 °C or 22 °C for up to 4 weeks. The effect of temperature on particle size and zeta potential was determined not to be statistically significant by two-way ANOVA (F(2,6) = 4.686, p = 0.0595). However, the effect of storage time was determined to be statistically significant for both particle size (F(2.163, 12.98) = 19.02, p = 0.0001) and zeta potential (F(1.679, 10.07) = 4.780, p = 0.0393).
