Study Notes

How Butterfly Wings Inspire Science

Butterfly wings change colour depending on viewing angle.
This is because the wings are made up of very thin layers that reflect light differently.
Scientists are trying to replicate this to develop solar panels.

Butterfly Wings Emit Light

Some butterfly wings emit light similar to LED's
This discovery could be used to improve LEDs.

Butterfly Wings Improve Sensors

The nanostructures on Morpho butterfly wings detect chemicals and heat.
The researchers are using this discovery to develop new sensors that can detect a wide range of chemicals.

Colourful and Water-Repellent Wings

Butterfly wings are both colourful and hydrophobic (meaning they repel water).
This is due to the nanoscale structures on the wings.

Transparent Surfaces

Transparent oil-repellent surfaces have potentially wide applications in biology and underwater optics.
Scientists are investigating the possibility of creating these through laser ablation.

Nano in Peacock Feathers

Peacock feathers exhibit iridescence.
The pigmentation in peacock feathers serves to absorb scattered light, making the interference colour more vivid.

Nanofotonic Crystals

The nanostructure of butterfly wings is an example of nanofotonic crystals.
The thickness of layers within these crystals determine the colour we see.

Biomimicry

Biomimicry is the study of how nature solves problems and how we can apply these solutions to human challenges.
Many organisms have evolved efficient ways to use their environment, and we can learn from these models how to solve problems more sustainably.

Gecko Feet

Gecko feet are covered in nano-sized hairs which stick to surfaces due to intermolecular forces (Van der Waals forces).
Scientists have developed an adhesive inspired by Gecko feet. This adhesive has the potential to seal wounds, patch holes in organs, and be used in various surgical applications.

Gecko Tape

Gecko tape is inspired by the adhesive capabilities of gecko feet.
Its potential applications include sealing wounds, repairing tissues, and creating new types of adhesives.

Gecko Shoes

Scientists have created shoes with gecko-inspired grip that improves stability and prevents slipping on rocky terrain.
Gecko shoes are especially useful for mountaineering and climbing activities.
