Engineered nanoparticles (ENPs) have been applied in various applications: biomedical, consumer products, electronic devices, and sensors. Field‐flow fractionation (FFF) is an interesting nonchromatographic technique for size characterization of materials with nanometer range. Various subtechniques of FFF including flow, sedimentation, and electrical are described with some selected applications reviewed. Moreover, FFF can be used via off‐line and on‐line with many elemental detection techniques: GFAAS, ICP‐OES, ICP‐MS, and SP‐ICP‐MS to provide more information in term of quantification and element‐specific detection. In this article, applications of FFF with atomic spectrometric detection for environmental and biological samples and consumer products and food‐related samples are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
