Nano-printing technology has made significant progress with up to 100,000 dots

U.S. Business Machines (IBM) Zurich Research Laboratory and Zurich University of Technology announced on the 11th that their nano-printing technology has made significant progress, enabling the use of nanoparticles to produce larger images, which will enable scientists, medical professors, and technical experts to On demand, accurately place particles smaller than 100 nanometers at the appropriate locations.

This is the first time researchers have used a 60-nanometer particle that is 33 million times smaller than a needle. If measured by the number of dots printed per square inch, this nano-printing technology can produce 100,000 dots, while the corresponding value of traditional offset printing is 1500 dots. Heck Wolff, a researcher at the IBM Zurich Research Laboratory Nanostructure Technology, claimed that "this is by far the most reliable method for placing particles."

The researchers said that although this method has not been commercialized in recent years, it will have a significant impact on biomedicine, electronics, and information technology. For example, in biology, the development of nanoscale biosensors can be promoted; nanowires can be used in semiconductor technology to make more advanced computer chips. Wolff said, "We have been looking for a technology to generate this type of nanowires." In medicine, nano-printing technology can be used to graphically represent the exact location of cancer cells in a patient.

In April of this year, researchers at the Massachusetts Institute of Technology in the US invented a new "nano-printing" technology that enables mass production of nanodevices such as DNA microarrays. With the development of science, from the biomedical to the information technology fields, the size and complexity of the components used have been continuously reduced. These requirements have motivated scientists to work hard towards nanometer printing with high resolution and high throughput. Technical direction for research.
