Resistive pulse sensing, based on the Coulter Counter principle, is an important assay for sensing and separation processes to detect/discriminate several types of particles in various mediums. In such a set-up, attaining signal from smaller can be hard compared larger particles. this work, we focus critical role pore shape precision. We have simulated hourglass cigar shaped nanopores study sen...

Abstract Synthesis of proton-conducting materials based on track-etched membranes from polyvinylidene fluoride and sulfonated cross-linked polystyrene is described. The synthesis has been carried out by filling the pores original or gamma-irradiated membrane copolymerization styrene/divinylbenzene followed sulfonation with chlorosulfonic acid. resulting have studied scanning electron microscopy...

BACKGROUND Multicomponent heterostructure nanowires and nanogaps are of great interest for applications in sensorics. Pulsed electrodeposition in ion-track etched polymer templates is a suitable method to synthesise segmented nanowires with segments consisting of two different types of materials. For a well-controlled synthesis process, detailed analysis of the deposition parameters and the siz...

Polycarbonate etched ion-track membranes with about 30 µm long and 50 nm wide cylindrical channels were conformally coated with SiO2 by atomic layer deposition (ALD). The process was performed at 50 °C to avoid thermal damage to the polymer membrane. Analysis of the coated membranes by small angle X-ray scattering (SAXS) reveals a homogeneous, conformal layer of SiO2 in the channels at a deposi...

Microand nanorods of potassium acid phthalate (KAP) with diameters ranging from a hundred nanometers to tens of microns were obtained by solution crystallization in the channels of ion-track membranes. The template consists of a polymer foil irradiated with energetic heavy ions and subsequently track-etched to dissolve the tracks and create open cylindrical channels. The pores are then filled w...
