From Nanohole to Ultralong Straight Nano-Channel Fabrication in Graphene Oxide with Swift Heavy Ions / A.Olejniczak, R.A.Rymzhanov // Nature Communications [Electronic resource]. – 2023. – Vol.14. – P.889. – URL: https://doi.org/10.1038/s41467-023-36357-8. – Bibliogr.:62.
Porous architectures based on graphene oxide with precisely tailored nm-sized pores are attractive for biofluidic applications such as molecular sieving, DNA sequencing, and recognition-based sensing. However, the existing pore fabrication methods are complex, suffer from insufficient control over the pore density and uniformity, or are not scalable to large areas. Notably, creating vertical pores in multilayer films appears to be particularly difficult. Here, we show that uniform 6–7 nm-sized holes and straight, vertical nanochannels can be formed by simply irradiating graphene oxide (GO) films with high-energy heavy ions. Long penetration depths of energetic ions in combination with localized energy deposition and effective self-etching processes enable the creation of through pores even in 10 µm-thick GO films. This fully scalable fabrication provides a promising possibility for obtaining innovative GO track membranes.
