Abstract

In the context of the extensive use of engineered nanomaterials (ENMs) in consumer products, industrial applications and nanomedicine, there is an important need of new methods for an exhaustive characterization of their physicochemical properties. Among them, surface hydrophobicity is considered as a key factor to be controlled, in particular for nanomedicine applications^1,2. The proposed study demonstrates the proof-of-concept of an inexpensive characterization process, enabling the sorting of ENMs according to their hydrophobicity and surface charge, together with the classical characterization of size and shape. The detection platform is based on the use of a surface modified through plasma polymer and layer-by-layer polyelectrolyte deposition in order to generate areas of tuned surface properties to bind ENMs selectively by hydrophobic forces and electrostatic interactions. The key advantages of such a device is the decrease of time and assay costs thanks to the all-in-one characterization process and the multiplexing that could replace the use of different methods and expensive equipment to give equivalent results. In this way, the full characterization of NP could be expanded in all the areas covering NP-related applications.
