As shown in Fig. 5(a), the results obtained from the NANOPOX (NX0064) particle size analyzer, 50% of the
particles were below 22.81 nm, whereas in graph (b) 50% of particles were below 29.09 nm. 90% of particles in graph (a)
were below 24.23 nm, whereas 90% of graph(b) particles were below 34.89. It is understood that the particle sizes of
the resultant silver nanocolloid do not change significantly even after 90 days from the initial synthesis. The narrow
peak in the density distribution curve (Fig. 6(a)) obtained from the NANOPOX (NX0064) has broadened and shifted to
the right side of the graph after 90 days of the initial synthesis (Fig. 6(b)). This indicated that the SNP becomes
agglomerated with time, resulting in larger sizes of nanoparticles with the size distribution of SNP in the nanocolloid
varying with time.
