It is hence possible that the described sudden drop marks such a morphological change, and that the lower apparent size is only representative of the cross-section of an elongated particle. While DLS is not able to provide further information in this instance (a problem generally faced in particle synthesis, only much more elaborated techniques such as small angle X-ray or neutron scattering can give insights into particle morphologies in solution directly), the automated measurement is nonetheless perfect to identify such sudden drops, and hence allows to find points of interest for further offline analysis rather than relying on serendipity to find morphology transitions.
