See in the dark without anyone knowing? Any military’s dream may be closer to materializing – all thanks to nanotechnology.
And if you see in the complete darkness was possible?
New contact lenses created by Chinese and Americans scientists contain artificial nanoparticles that absorb and convert infrared radiation – Specifically, a range of wavelengths of 800 to 1600 nanometers in nearby infrared – in blue, green and red light visible to the human eye.
According to, one thinks of future applications to new contact lenses.
“As contact lenses would provide the military personnel discreet vision skills and without the need to use hands, surpassing the limitations of bulky night vision glasses, ”exemplifies the scientist Peter Rentzepis.
The nanoparticles (sodium gadolinium fluoride, itérbio and erbium) made them into humans and rats, converting a flash normally invisible of infrared light into a “large colorful spot of visible light,” he says Mikhail Katsresearcher at the University of Wisconsin-Madison, who was not involved in the investigation.
There is still room for improvements, and for now the technology is not fully developed – and they can only capture LED light sources of “high intensity and narrow band ”.
As Kats states, the one published in the magazine Cell This month is “bold”, and “using only contact lenses, it would not be possible to read a book in the infrared or sail along a dark road.”
However, the advance is significant. Outdated the safety testing phase and achieved its practical application, these discreet lenses can say a lot to Future of War Technology -And from everyday life.
