Thus, developing efficient experimental methods that are able to provide accurate and reproducible measures of the NP properties is a considerable challenge for both research and industrial development. By analyzing different NPs, through size and concentration, it is demonstrated that lock‐in thermography, based on light absorption and heat generation, is able to detect and differentiate the distinct aggregation and re‐ dispersion behavior of plasmonic NPs, e.g., gold and silver. Most importantly, the approach is nonintrusive and potentially highly cost‐effective compared to standard analytical techniques. application/pdf https://sonar.ch/global/documents/308101 https://sonar.ch/documents/308101/files/pet_lit.pdf https://sonar.ch/documents/308101/files/pet_lit_sm.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1002/ppsc.201900224 info:eu-repo/semantics/openAccess License undefined Particle & Particle Systems Characterization. - 2019, p. 1900224 info:eu-repo/classification/udc/54 Lock‐in thermography to analyze plasmonic nanoparticle dispersions http://purl.org/coar/resource_type/c_6501
