Fig. Average diameters of nine AuNP batches measured with DLS, SPA, SEM and AFM.
The four different techniques yielded AuNP diameters with systematic differences. SEM showed the largest and SPA the smallest diameter for the same batch of AuNPs. The discrepancy in NP diameter could be because the mentioned techniques measure different aspects of the NPs. The main conclusion was that using several techniques to estimate NP size might provide a better understanding about their size and shape.
