Digital Microneedles for Multiplexed Transdermal Sensing via Fluorescent QR Codes
Advanced Materials, EarlyView.Digital fluorescent microneedles encode biochemical information in skin into scannable QR codes through threshold‐activated probes that generate binary on/off signals. By transforming analog fluorescence into discrete digital patterns, this platform enables calibration‐free, multiplexed transdermal sensing of physiologically relevant biomarkers ...

Cone visual pigments.Cone visual pigments are visual opsins that are present in vertebrate cone photoreceptor cells and act as photoreceptor molecules responsible for photopic vision. Like the rod visual pigment rhodopsin, which is responsible for scotopic vision, cone visual pigments contain the chromophore 11-cis-retinal, which undergoes cis-trans isomerization resulting

Advanced Materials, EarlyView.We report a multifunctional tapered optical fiber integrating a conformal micro‐resistance temperature detector (µRTD) for local, real‐time thermometry during optical stimulation. The platform combines light‐delivery and temperature sensing within a minimally invasive footprint, enabling detection of sub‐degree cortical heating under representative ...

American Journal of Ophthalmology Case ReportsPurpose: Rhegmatogenous retinal detachment (RRD) can cause permanent photoreceptor damage with subsequent vision loss, even after prompt repair. Here we compared photoreceptor structure in retinal areas with varying levels of residual visual function ...

Visual adaptation and the cone flicker electroretinogram.
Investigative ophthalmology & visual science, 1991 This study examined the hypothesis that changes in the response properties of the human cone ERG during light adaptation represent the recovery of cone system responsiveness toward a dark-adapted value after an initial decrease in responsiveness at adapting field onset.
