In many biological systems such as insects, fish, birds and flowers, the common way to produce the most brightly coloured appearances is by strong reflection from ordered arrangements of nanostructures. These are referred to as photonic crystals.
Study of these systems is informing a broad range of sciences, providing not only functional, behavioural and materials understanding, but also suggesting protocols with which light, colour and appearance manipulation in technology may be more effectively embraced.
This presentation will offer an overview of the field of biological photonics, and will present in detail several recent discoveries that reflect nature’s optical design ingenuity, combined with some technological applications for which they are currently being developed.
