abstract = {Molecular recognition is the key feature of bioinspired
sensor applications. A profound understanding of recognitive
binding events is crucial for the design of highly specific
and effective binding molecules. In this paper a series of
simple to complex oligopeptides, derived from the Ca2+
chelator ethylenediaminetetraacetic acid (EDTA) and the Ca2+
binding protein calmodulin, were investigated. It was shown,
that specifically designed oligopeptides can fulfil
protein-like recognition functions but are much easier to
immobilize and enable high functional integration. Impedance
spectroscopy (IS) could be used to detect binding of Ca2+ to
different peptides because the double layer capacitance is
highly sensitive to changes in the morphology and dielectric
properties of adsorbate layers. Finally, the designed
functional oligopeptides were implemented in silicon
nanowire field effect transistors (SiNW FETs) as a proof of
concept for future problem-optimized molecules in sensor
devices.},
