Man can learn many things from nature. Animals have the most natural way of doing things. Moth has an incredible system of eye movements that can help defend it in dangerous situations. One of the amazing things about a moth’s eye is its absorption of light. This characteristic is something that has caught the attention of the engineers and they want to do the same. They have copies its nanostructure for better designed solar panel coatings so that sunlight can be absorbed at maximum.

Now engineers are focused on getting this light absorption technology to X-ray machines, which would make them more effective and less dangerous to humans. The images taken from these would also be of high quality. The scientists are concentrating on scintillation materials, which make this characteristic possible. The energy from a particle hitting such scintillation materials is totally absorbed and then emitted out in the form of light.

Scintillators are being used in different medical imaging devices that convert X-rays reflected from patients into visible signals, which then gives doctors a final scan. Making medical devices safe and easy to use is of great help. In part in eases out a patient from the scare of undergoing a medical treatment when procedures are explained to him or her by a doctor.

Researchers have now developed a film that is only 500 nanometers thick and has bumps of silicon nitride that actually works as a moth’s eye. Further details of this new research can be found published in the journal Optics Letters.
