Description

Nanotechnology is creating new discoveries in areas such as medicine, automotive, energy, agriculture, remediation, consumer products and the entertainment industry. Central to the core of sustainable nanotechnology is the need to develop characterization parameters, metrological tools and protocols that can provide information on the interactions of engineered nanomaterials with complex matrices. In this presentation, I will discuss conventional and emerging techniques that are available for characterizing engineered nanoparticles in complex matrices. I will also review the need to develop new instruments and/or further refinement of existing tools. Examples include microscopy (TEM, SEM, HRTEM, DLS, SNOM), chromatography (HDC, FFF), mass spectroscopy (ICP-MS, SEC-ICP/MS, MALDI, FFF-ICP-MS), sp-ICP-MS and electrochemical techniques. Case studies will be presented from the authors’ laboratories for the design of a portable nanoparticle analyzer based on tangential flow filtration and electrochemical detection (EC-TFF). The development of personal monitors for nanoparticles that are equipped with poly (amic) acid membrane filter electrodes (PMFE) arrays to track, capture, isolate, and detect engineered nanoparticles will be discussed. Finally, I will present current research in our laboratory focusing on novel sensors for nanostructured silver, Fe2O3, fullerenes, TiO2 and ceria.
