Figure 2: Cumulative size distribution and frequency of 0.5% IMC solid nanoparticles. IMC solid nanoparticleswere prepared as outlined in Figure 1. Particle size was determined using a nanoparticle size analyzer SALD-7100 (refractive index 1.60- 0.10i). Particle size: micro IMC, 17.2 ± 12.8 μm; IMCnano,76 ± 59 nm (mean ± S.D.).
