Figure 2. Physicochemical characterization of anionic HB-surface assembled CSNC prototypes.

Figure 2

Particle size, polydispersion (PdI) and ξ potential evolution of CSNC:HB when CSNC suspension was sequentially diluted. The ratio CSNC:HB which exhibited the most adequate physicochemical properties (black column) was: particle size 310 nm ±34; polydispersity index 0.33±0.04; ξ potential −23 mV ±3. Mean ± SD.
