How Does the Nanofountain Probe Achieve Nanoscale Writing Precision?

The Nanofountain Probe

A Technological Marvel Unveiling the World of Nanoscale Writing

Did you Know?

While the familiar pen remains a ubiquitous tool for recording thoughts and ideas, a revolutionary new design has emerged, operating on a far smaller scale: the Nanofountain Probe. Developed by researchers at Northwestern University, the Nanofountain Probe represents a significant advancement in nanotechnology. This groundbreaking tool can write lines as narrow as 40 nanometers – roughly 1/2000th the width of a human hair – representing a substantial leap in nanotechnology.

Unlike the everyday pen, the Nanofountain Probe isn’t designed for scribbling on paper. It is used in:

  • Electronics: Development of miniaturized circuits, leading to faster, more efficient devices.
  • Medicine: Creating targeted drug delivery systems and nanoscale biosensors for improved diagnosis and treatment.
  • Materials science: Design of materials with unique properties and applications, paving the way for innovative products and technologies.

The Nanofountain Probe operates through a sophisticated microfluidic system. Specialized “inks,” such as molecules and nanoparticles, are delivered to a volcano-like tip, where they are precisely deposited onto surfaces, creating intricate and precise patterns. This remarkable process relies on the same capillary forces that govern ink flow in traditional fountain pens, ensuring continuous and controlled material delivery at an unprecedentedly small scale.
