Engineered nanomaterials (ENMs) are of high innovative potential with a large number of possible applications in a variety of fields (e.g., electronics, energy generation and storage, photonics, diagnostics or as drug delivery agents). The large-scale use of ENMs raises concerns about their safety for humans and the environment.
A large variety of methods are available for analyzing the properties of ENMs and observing their fate in biological and ecological systems. Common attributes of these methods are: i) high price for analysis and instrumentation, ii) complex data analysis, iii) complex sample preparation.

A new approach for the analysis of ENMs will be presented, based on the analysis of heat produced by light-stimulation. The method is easy-to-use, does not require complex sample preparation of data analysis and can be used for a fast screening of ENM presence, dispersion states and other properties.
