Summary

Automatically generated

Il protocollo qui descritto mira a misurare il diametro idrodinamico delle nanoparticelle sferiche, più specificamente nanoparticelle d'oro, in mezzi acquosi attraverso l'analisi di tracciamento delle nanoparticelle (NTA). Quest'ultimo comporta il tracciamento del movimento delle particelle dovuto al moto browniano e l'implementazione dell'equazione di Stokes-Einstein per ottenere il diametro idrodinamico.
