Characteristics of chol-but SLN

	Diameter±s.e.m. (nm)	Polydispersity index±s.e.m.	Zeta potential (mV)	Nanoparticles in 1 ml dispersion (approx. number)^*
Chol-but SLN	160±11	0.20±0.02	−28	4.6 × 10¹⁴
Chol-but SLN (fluorescent)	130±21	0.28±0.02	−29	8.7 × 10¹⁴

Computed from average nanoparticle diameter (spherical shape and density=1).

SLN aqueous dispersion concentration: 12 mM.

The average diameter and polydispersity index of chol-but SLN dispersions were maintained in BSS solution for 4 h.
