figurE 30.2
Schematic representation of an engineered nanomaterial (ENM). The core determines some of the physical properties of the
material; the layer consists of molecules acting as stabilizers or modifying agents; the capping acts as an agent to increase biocompatibility,
change charge, and solubility; the biomarker/fluorophore/recognition agent generates specifity for recognizing a substrate or detecting the
nanomaterial.
