![Coupled bilayer nanopore concept for physical guiding, tracking and sizing of single molecules a, Fabrication schematic including EBL, etching, 2D materials transfer and AC-STEM sculpting. SiN nanopores constitute a GURU platform. Pore thicknesses are tSiN and t2D, diameters are dSiN and d2D and the total thickness is tGURU. Device configurations are denoted as [N, M] for N SiN pores and M 2D pores. σSiN and σ2D denote surface charge densities of SiN and 2D pores, respectively. The interlayer separation, L, can be experimentally controlled by the duration of RIE. -- Nature](https://i0.wp.com/astrobiology.com/wp-content/uploads/2024/09/Tricorder-Tech-Novel-Coupled-Nanopore.png?resize=1200%2C719&ssl=1)
Editor’s note: As we begin to expand our search for life to other worlds we are going to need to be economical interms of the equipment we send and how […]
Tardigrades, often called “water bears”, are fascinating microscopic organisms known for their incredible resilience—they can survive anything from deadly radiation to arctic temperatures to the vacuum of space. And though […]
In a study published today (22 August) in Cell Reports Physical Science, a team led by Dr Yoshikatsu Hayashi demonstrated that a simple hydrogel – a type of soft, flexible […]
“DNA, RNA and proteins are the key players to regulate all processes in the cells of our body,” Leiden Professor John van Noort explains. “To understand the (mis-)functioning of these […]
Who are we? Why are we here? As the Crosby, Stills, Nash & Young song suggests, we are stardust, the result of chemistry occurring throughout vast clouds of interstellar gas […]
Since the industrial revolution, microbes have successfully colonized one novel type of habitat after another: for example marine oil spills, plastic floating in the oceans, industrial brownfields, and even the […]
Space agencies and private companies strive for a permanent human presence on the Moon and ultimately on Mars. Bioprocesses have been advocated as key enablers due to their ability to […]
Our understanding of the cellular adaptations to extreme conditions (such as acid, temperature, pressure and more), of the mechanisms underpinning the stability of macromolecules, and of the subtleties, complexities and […]
This paper presents initial results from the ESA-funded “SUPPPPRESS” project, which aims to develop high-performance liquid-crystal coronagraphs for direct imaging of Earth-like exoplanets in reflected light.
Nanopore sensing is a powerful tool for the detection of biomolecules. Solid-state nanopores act as single-molecule sensors that can function in harsh conditions. Their resilient nature makes them attractive candidates […]
