Gentle Label‐Free Nonlinear Optical Imaging Relaxes Linear‐Absorption‐Mediated Triplet

Advanced Science, EarlyView.
The phototoxicity in nonlinear optical microscopy arises mainly from linear absorption of intrinsic biomolecules rather than nonlinear absorption. This mechanism is supported by a reproducible phototoxicity assay based on widely available chicken breast.

Determination of melanin types and relative concentrations: an observational study using a non-invasive inverse skin reflectance analysis [PDF]

, 2014
Objective: Melanin is a major skin colour pigment that made up of eumelanin (the dark brown–black colour) and pheomelanin (the light red–yellow colour) pigments.

Regenerative Hair Pigmentation via Skin Organoids: Adaptive Patterning Mediated by Collagen VI and Semaphorin 3C

Advanced Science, EarlyView.
The release of COL6A3 by fibroblasts is sensed by the CD44 receptor on melanocytes, activating glutathione (GSH) metabolism and increasing melanocyte survival during skin organoid culture. SEMA3C released by bulge cells binds to the NRP1 receptor on melanocytes, regulating microtubule stability and promoting melanocyte recruitment and function during ...

Skin Protection by Carotenoid Pigments

International Journal of Molecular Sciences
Sunlight, despite its benefits, can pose a threat to the skin, which is a natural protective barrier. Phototoxicity caused by overexposure, especially to ultraviolet radiation (UVR), results in burns, accelerates photoaging, and causes skin cancer formation. Natural substances of plant origin, i.e., polyphenols, flavonoids, and photosynthetic pigments,

Bio‐Inspired Strategy for Radiation‐Based Thermal Management and Utilization

Advanced Science, EarlyView.
Biological organisms have evolved remarkable strategies to manage and exploit thermal radiation. This review explores bio‐inspired systems that mimic these adaptations—such as radiative cooling, thermal regulation, thermal insulation, water harvesting, infrared camouflage, and infrared detection—and highlights their application in thermal management ...

A comparative study of an advanced skin imaging system in diagnosing facial pigmentary and inflammatory conditions

Scientific Reports
Visual assessment, while the primary method for pigmentation and erythema evaluation in clinical practice, is subjective, time-consuming, and may lead to variability in observations among clinicians. Objective and quantitative techniques are required for
