Kinetics of phage aggregation—dependence on ionic strength. a Under low ionic strength, the particles of phage rapidly aggregate to form clusters. The initial high rate of aggregation gradually slows down, with plateau in the late phase. Measured values fit to square-root function curve, shown in green. b The curves demonstrate DLS analysis where the particles of phage do not cluster when in high ionic concentration (red curve) while, upon ionic strength switched to the low range, the aggregation followed (green curve). These two contrasting behavior modes correspond to the clustering of nanoparticles, dynamic under liquid suspension conditions, and correlate well with observations of the static methods SEM and AFM
