Particle size and polydistribution index (PDI) of SAP conjugate aggregates in water versus its concentration. The particle size of the SAP conjugate is around 180Â nm when the concentration of SAP is less than 2Â mM and the corresponding PDI is 0.3; represents a narrow distribution (or monodisperse). With increase in the concentration of SAP beyond 2Â mM, the particle size of SAP conjugate quickly increased, suggesting a broad PDI (or polydisperse)
