Charge screening and hydrophobicity drive progressive assembly and liquid–liquid phase separation of reflectin protein Open
The intrinsically disordered reflectin proteins drive tunable reflectivity for dynamic camouflage and communication in the recently evolved Loliginidae family of squid. Previous work revealed that reflectin A1 forms discrete assemblies who…

Protein Charge Neutralization Is the Proximate Driver Dynamically Tuning Reflectin Assembly Open
Reflectin is a cationic, block copolymeric protein that mediates the dynamic fine-tuning of color and brightness of light reflected from nanostructured Bragg reflectors in iridocyte skin cells of squids. In vivo, the neuronally activated p…

A colloidal model for the equilibrium assembly and liquid-liquid phase separation of the reflectin A1 protein Open
Reflectin is an intrinsically disordered protein known for its ability to modulate the biophotonic camouflage of cephalopods based on its assembly-induced osmotic properties. Its reversible self-assembly into discrete, size-controlled clus…

Synthesis of thin films and materials utilizing a gaseous catalyst Open
A method for the fabrication of nanostructured semiconducting, photoconductive, photovoltaic, optoelectronic and electrical battery thin films and materials at low temperature, with no molecular template and no organic contaminants. High-q…

Electrochemistry as a surrogate for protein phosphorylation: voltage-controlled assembly of reflectin A1 Open
Phosphorylation is among the most widely distributed mechanisms regulating the tunable structure and function of proteins in response to neuronal, hormonal and environmental signals. We demonstrate here that the low-voltage electrochemical…

Molecular mechanism of reflectin’s tunable biophotonic control: Opportunities and limitations for new optoelectronics Open
Discovery that reflectin proteins fill the dynamically tunable Bragg lamellae in the reflective skin cells of certain squids has prompted efforts to design new reflectin-inspired systems for dynamic photonics. But new insights into the act…

Wavelength-specific forward scattering of light by Bragg-reflective iridocytes in giant clams Open
A surprising recent discovery revealed that the brightly reflective cells (‘iridocytes’) in the epithelia of giant clams actually send the majority of incident photons ‘forward’ into the tissue. While the intracellular Bragg reflectors in …

Biological analogs of RGB pixelation yield white coloration in giant clams Open
Giant clams utilize two mechanisms to produce white coloration analogous to that from RGB pixelated electro-optical displays. In the first, the mixed reflection from tight clusters of differently colored iridescent cells yields white. In t…

Cyclable Condensation and Hierarchical Assembly of Metastable Reflectin Proteins, the Drivers of Tunable Biophotonics Open
Reversible changes in the phosphorylation of reflectin proteins have been shown to drive the tunability of color and brightness of light reflected from specialized cells in the skin of squids and related cephalopods. We show here, using dy…
