Guinness World Record smashed by QR code pixel just 50nm - 2500 sq nanometer size is smaller than COVID-19 virus, needs electron microscope to read it

Covid-19 silver Cerabyte Monash University
Monash University School of Physics and Astronomy researchers stood next to the photo of their record breaking QR code.
  • Microscopic QR code measures just 50 by 50 nm² and is constructed using singular atoms of silver
  • Researchers used quantum tunnelling techniques and automation to apply individual atoms to a mounting surface, with human intervention for fine adjustment
  • The QR code is still scannable using a mobile phone despite being 800 times smaller than the current record holder

Researchers at the Monash University School of Physics and Astronomy and the Czech Academy of Sciences may have just shattered the Guinness World Record for smallest QR code, with their entry measuring almost 800 times smaller than the previous record.
