In this work, we have focused on the analysis of EBC. A challenging aspect of the EBC analysis is the rather low concentrations of the analytes, which are considerably lower than in plasma or urine samples. We first describe an in-house built device that allows collection of sufficient amount of EBC (several mililiters, at -20 °C). A selective preconcentration by using gold nanoparticles and utilization of gold-thiol interaction, is then employed as a first step. The gold nanoparticles could be used as they are, or, they can be grafted onto a magnetic nanoparticle core, which enables magnetic separation.
