Photonic Crystals and Applications

Nudibranch color diversity shares a common origin in guanine photonic structures

This paper identifies guanine-based multilayer structures as a common mechanism for structural coloration in nudibranchs across multiple species.

Controlled pH Alteration Enables Guanine Accumulation and Drives Crystallization within Iridosomes

The paper investigates the role of pH changes in guanine accumulation and crystallization within zebrafish iridosomes, showing that acidic conditions and V-ATPase activity drive crystal formation.

Decoding ladybird's colours: structural mechanisms of colour production and pigment modulation.

This study examines color production in ladybirds, showing that color results from both pigments and optical properties of the elytra, with physical mechanisms operating alongside pigments.

Design and fabrication of recombinant reflectin-based Bragg reflectors: bio-design engineering and photoisomerism induced wavelength modulation

The paper designs and fabricates a bio-inspired reflectin-based Bragg reflector that modulates optical properties via visible light-induced photoisomerism.

Design of DNA Origami Diamond Photonic Crystals

This paper designs DNA origami-based photonic crystals with a complete photonic bandgap in the visible range, using numerical analysis to optimize structural and mechanical properties.

Neutralization of a Distributed Coulombic Switch Precisely Tunes Reflectin Assembly

The paper investigates how neutralization of cationic linkers in reflectin proteins tunes their assembly into multimeric spheres, revealing a predictive relationship between charge neutralization and assembly size.
