MAT Collaboration Meeting 2026

Over the past three decades, interest in nanoporous structures—including
single nanopores and nanoporous membranes—has grown enormously. Nanopores have
become powerful platforms for fabricating biomimetic channels, developing
model systems for exploring new nanoscale phenomena, and creating single-
molecule biosensors. Nanopores enabled DNA sequencing and progress has been...

Nanofluidic memristors have emerged as promising substrates in neuromorphic computing applications due to their programable conductance memory states that are reminiscent of the brain synapses. We explore different options for the modulation of the conductance of track-etched conical nanopores by programming series of rectangular voltage pulses of different characteristics: amplitude,...

Over the past years, our group has explored the use of bioinspired solid-state nanochannels and nanofluidic architectures as versatile platforms for controlling ionic transport at the nanoscale. Inspired by the remarkable transport and gating mechanisms found in biological ion channels, our research has focused on understanding how confinement, surface chemistry, molecular recognition, and...

Nanofluidic membranes can be used to harvest energy from salinity gradients, and bullet-shaped nanochannels offer promising characteristics, as their asymmetric geometry enhances power output relative to other nanochannel shapes [1]. For practical applications, however, energy conversion must be scaled from individual nanochannels to membranes containing large number of pores. In this...

Swift heavy ions deposit enormous electronic energy densities in solids, leading to the formation of latent ion tracks that provide a unique platform for investigating radiation–matter interactions under extreme conditions. Beyond their fundamental scientific significance, ion tracks have emerged as an enabling tool for the fabrication of nanoporous membranes, nanostructures, and advanced...

Ion-track etched membranes provide a versatile platform for the fabrication of highly ordered one- and three-dimensional (3D) nanostructures with precisely controlled architectures. Such control over nanoscale geometry, connectivity, and interfaces is essential for understanding how structure governs material properties and for developing functional nanostructured materials. At GSI, polymer...
