Micro/Nanopore Fabrication

Nanopore-based sensors have established themselves as a prominent tool for various applications such as resistance pulse sensing (RPS) systems for detecting the physical properties of particles, particle gating systems, and developing pressure sensors. One of the goals pursued in developing resistance pulse sensing systems is detecting and sequencing DNA molecules. To achieve this goal, it is desirable to make a nanopore with several tens of nanometer dimensions. In general, the smaller the size of the pore, the better the output quality of the sensor. Nanopore fabrication with low-cost methods is one of the challenges in this field.

In the Micronanosystem laboratory, we are trying to find low-cost methods for nanopore fabrication by focusing on the pore fabrication methods and the development of the electronic system. In addition to nanopore fabrication, numerical simulation, new applications, changing the dimensions of the pore by new mechanisms, and designing systems with commercialization capabilities are ongoing activities in our laboratory. In the numerical simulation field, the effect of nanopore geometry on resistive pulse sensing and the impact of off-axis on pulse amplitude has been studied. Among the systems with commercialization capabilities, we can mention the particle counter, which was designed and developed in this laboratory.
