As the author shows, Classical views of Homer differ significantly from those prevailing today, and this allows the conception of the Aeneid to be seen in a new light. In the first part of the study, the author analyses the way in which Virgil indirectly characterises the protagonists of his epic (incl. Aeneas, Turnus, Dido) through allusions to the contemporary philosophical and ethical understanding of Homer`s models. In the second part, the author examines how the "poeta doctusR

In recent years, SICM has been applied in an ever-increasing number of areas in the bioanalytical sciences. SICM is based on an electrolyte-filled nanopipette with a nanometer-scale opening, over which an electric potential is applied. The induced ion current is measured, which allows to directly or indirectly quantify various physical quantities such as pipette-sample distance, ion concentration, sample elastic modulus among many others. This makes SICM well suited for applic
