Abstract

Solid-state nanofluidic pores have been attracting considerable attention of scientific community because of their structural and chemical resemblance with biological ion channels for mimicking biological processes in living systems. Compared to ion channels, synthetic nanopores exhibit high stability, control over pore dimensions (size and geometry) and their surface chemical properties can be tuned on demand. Therefore, they are considered perfect candidates to design and develop nanofluidic sensory devices by introducing a variety of functional moieties on the inner pore surface. Here, we present a nanofluidic pore for the recognition of potassium cations using acyclic polyether derivative in confined environment. To this end, amine terminated acyclic polyether derivative (bis-podand-NH
