Abstract Recently, research interest in brain‐inspired neuromorphic computing based on robust and intelligent artificial neural networks has surged owing to the ability of such technology facilitate massive parallel, low‐power, highly adaptive, event‐driven computing. Here, a photosynaptic device with novel weight updating mechanism for high‐speed low‐power optoelectronic spike processing is proposed, wherein synaptic controlled by mixed consisting voltage light spikes; spike, particular,...
Assess the ability of a panel gingival crevicular fluid (GCF) biomarkers as predictors periodontal disease progression (PDP).In this study, 100 individuals participated in 12-month longitudinal investigation and were categorized into four groups according to their status. GCF, clinical parameters saliva collected bi-monthly. Subgingival plaque serum bi-annually. For 6 months, no treatment was provided. At patients received therapy continued participation from 12 months. GCF samples analysed...
Because of the salient impact on performance oxygen evolution reaction (OER), surface dynamics precatalysts accompanying oxidation and dissolution catalytic components demands immense research attention. Accordingly, change in structural integrity under high current density generally results inconsistent OER performances. To address this challenge, here, we present intricate design precatalysts, strategically followed by reconstruction treatment presence Fe water condition, which...

Severe tooth decay has been associated with iron deficiency anemia that disproportionally burdens susceptible populations. Current modalities are insufficient in severe cases where pathogenic dental biofilms rapidly accumulate, requiring new antibiofilm approaches. Here, we show ferumoxytol, a Food and Drug Administration-approved nanoparticle formulation for treating deficiency, exerts an alternative therapeutic activity via the catalytic activation of hydrogen peroxide, which targets...

Dental caries is the most common human disease caused by oral biofilms despite widespread use of fluoride as primary anticaries agent. Recently, an FDA-approved iron oxide nanoparticle (ferumoxytol, Fer) has shown to kill and degrade caries-causing through catalytic activation hydrogen peroxide. However, Fer cannot interfere with enamel acid demineralization. Here, we show notable synergy when combined stannous (SnF
Polymeric three-dimensional inverse-opal (IO) structures provide unique structural properties useful for various applications ranging from optics to separation technologies. Despite vast needs IO functionalization impart additional chemical properties, this task has been seriously challenged by the intrinsic limitation of polymeric porous materials that do not allow easy penetration waterborne moieties or precursors. To overcome restriction, we present a robust and straightforward method...
The eradication of biofilms remains an unresolved challenge across disciplines. Furthermore, in biomedicine, the sampling spatially heterogeneous is crucial for accurate pathogen detection and precise treatment infection.
