Believe it or not, what you see here is the smallest inkjet color photo ever printed. She is so small that she is invisible naked eye. You will need a microscope to see it.
Η inkjet printed photo shows clown fish circling a sea anemone that is also their home. Photo produced by researchers on ETH of Zurich.
Using a groundbreaking technology called 3D NanoDrip invented at the university, the team was able to print the photo of 80 × 115 micrometers (micrometers = millimeters of millimeters) or about 0,0092 square millimeters.
The above number is equivalent to the cross-section of a human hair, or if you want a pixel in a super-high analysiss Retina display.
This scale was achieved thanks to something called quantum dots (QDs), or nanoparticles that can emit light συγκεκριμένου χρώματος. Η εξαιρετικά μικρή φωτογραφία που προέκυψε έχει χαρακτηριστεί επίσημα στον κόσμο ως η “μικρότερη inkjet εκτυπωμένη έγχρωμη εικόνα” σύμφωνα με Guinness World Records.
