Pigment identification with optical coherence tomography and multispectral imaging [PDF]

open access: yes, 2008
We describe a new method for non-invasive pigment identification by combining the spectral reflectance in the visible spectrum with near infrared OCT cross-section images of the subsurface layer ...

Distinct genetic origins of eumelanin levels and barring patterns in cichlid fishes.

open access: yesPLoS ONE
Pigment patterns are incredibly diverse across vertebrates and are shaped by multiple selective pressures from predator avoidance to mate choice. A common pattern across fishes, but for which we know little about the underlying mechanisms, is repeated ...

Retinal pigment epithelial disruption after retinal detachment repair using perfluorocarbon liquid and gas tamponade: a case series

open access: yesAmerican Journal of Ophthalmology Case Reports
Purpose: To describe two cases of central visual disturbances following uncomplicated pars plana vitrectomy for macula-on retinal detachment. Observations: Both patients exhibited a distinctive angled pattern of focal disruptions of the retinal pigment ...

All‐Amyloid Functional Coacervates

open access: yesAdvanced Materials, EarlyView.
This study introduces an all‐amyloid interfacial complex coacervate technique that employs charge‐mediated or functionalization‐assisted complexation of oppositely charged food protein‐derived amyloid nanofibrils to engineer functional soft constructs across multiple length scales.

Imaginal disc growth factor maintains cuticle structure and controls melanization in the spot pattern formation of Bombyx mori.

open access: yesPLoS Genetics, 2020
The complex stripes and patterns of insects play key roles in behavior and ecology. However, the fine-scale regulation mechanisms underlying pigment formation and morphological divergence remain largely unelucidated.

Ionic Gating of Liquid‐Crystal‐Like Pteridine Assemblies Enables Tunable Light Scattering

open access: yesAdvanced Materials, EarlyView.
Tunable optical properties emerge through developmentally regulated ionic gating, which transforms disordered, ultraviolet (UV)‐absorbing organelles into concentrically ordered, liquid‐crystal‐like light scatterers. By integrating analyses of pteridine composition, potassium‐dependent assembly, hierarchical ultrastructure, and optical behavior, the ...

Multi‐Biomimetic Structural Colors Inspired by Pearls and Bird Feathers

open access: yesAdvanced Materials, EarlyView.
A dual‐biomimetic strategy mimicking pearls and bird feathers is proposed to construct full‐gamut structural colors. By integrating a non‐strictly periodic inorganic multilayer architecture with tunable light absorbers, this facile approach circumvents the complex fabrication of traditional 1D photonic crystals, offering immense potential for cosmetics,

Inverse Design of Nanoparticulate Materials

open access: yesAdvanced Materials, EarlyView.
Inverse design shifts nanomaterial development from empirical trial‐and‐error to predictive model‐driven strategies. It can rely on knowledge‐based, data‐based, or hybrid process and property functions. This perspective article provides a practical framework for applying inverse design based on instructive examples. It discusses which modeling approach

Dermoscopy of Vitiligo and Other Hypopigmented Skin Lesions in Indian Patients: A Cross-Sectional Study

open access: yesDermatology Practical & Conceptual
Introduction: Non-vitiligo hypopigmented skin lesions may be close clinical mimickers of vitiligo, resulting in a diagnostic dilemma. Dermoscopic features of vitiligo have been studied, but those of other hypopigmentation disorders are not well ...
