Affordable method for making Silicon Nitride Nanopore with Simple Chemical Etching (ACS Nano, 2022)

We demonstrated DNA translocations through silicon nitride pores formed by simple chemical etching on glass substrates using microscopic amounts of hydrofluoric acid. DNA translocations and transmission electron microscopy (TEM) prove the fabrication of nanopores and allow their characterization. This simple and affordable chemical method for making solid-state nanopores accelerates their adoption for molecule sensing and characterization applications.
