Extremely small

Nanotechnology is the study of extremely small objects, their interaction with each other and the manipulation of matter on a molecular scale to create functional materials and devices.

Really, really small pixels of colour

Materials at the nano-scale are measured in nanometres (nm). 1 nm equals one billionth of a metre.

Nanotechnology in nature

The translucent wings of a Blue Morpho butterfly consist of billions of tiny structures, resembling nano-sized fir trees. These tiny structures interact with light at a molecular scale to produce the bright blue colour of the Morpho. The effect is created naturally through the reflection, refraction and absorption of light off of a grid of nano-structures that make up the surface of the wings. Butterflies have developed these nano-structures through a biological process that evolved over millions of years. These butterfly structures were an inspiration for the KolourOptik nano-structures we use today.

40,000 nano-holes on the tip of a pencil

KolourOptik technology uses nano-sized indentations to create vibrant colour images which, when light reflects off of them, appear similar to an LED display. It’s like we’re putting all the pixels from a big screen TV on an object only a few millimeters in size.

The nano-structures that make up Nanotech’s KolourOptik features are 50 nm to 250 nm. A standard tip of a pencil would contain 40,000 indentations if a 50nm indentation was used.

3 Element Security Pyramid

KolourOptik® technology is the first technology to encompass the “3 Element Conventional Security Pyramid” all in one technical application.
