Synergistic Interactions of Metals and Quantum Dots: Expanding Frontiers in Fluorescent Sensing.

Fluorescent sensing technologies have emerged as powerful tools in analytical science, offering exceptional sensitivity and selectivity for detecting a wide range of analytes. Among the advanced materials driving these technologies, quantum dots (QDs) and metal nanoparticles (MNPs) stand out due to their unique optical and electronic properties. When combined, these materials exhibit synergistic interactions those significantly enhance the fluorescence signals, enable efficient quenching, and offer tunable optical properties.

Comparative Analysis of CBCT vs Intraoral Radiography for Interproximal Caries Detection: A Prospective Diagnostic Study.

Background: Cone-beam computed tomography (CBCT) and intraoral radiography are important imaging modalities for detecting interproximal caries, but their comparative diagnostic accuracy is not well established.

Objective: This prospective clinical study aimed to compare the diagnostic accuracy of CBCT and intraoral radiography in detecting interproximal caries.

Methods: A cohort of 248 adult dental samples with suspected or diagnosed interproximal caries underwent both CBCT and intraoral radiography using standardized protocols.

Novel PPAR-γ agonists as potential neuroprotective agents against Alzheimer's disease: rational design, synthesis evaluation, PPAR-γ binding assay and transactivation and expression studies.

Alzheimer's disease (AD) is a neurological disorder. It is caused by accumulation of amyloid beta (Aβ) plaques and tau tangles, which gradually leads to cognitive decline and memory loss. Peroxisome proliferator-activated receptor gamma (PPAR-γ), a nuclear receptor, plays a significant role in regulating genes responsible for metabolism and inflammation.

Ferromagnetic ZnO nanostructures from an organo zinc complex formulated via Piper Longum L-assisted green synthesis: Multifaceted prospects in photocatalysis, antimicrobial activity, and cell viability studies.

Transition metal oxides like ZnO nanostructures are pivotal in various scientific and technological fields due to their chemical stability, high electrochemical coupling efficiency, and broad radiation absorption spectrum. This study offers an in-depth examination of ZnO nanostructures synthesized via the green route using Piper Longum L, emphasizing their photocatalytic efficacy in degrading organic pollutants such as Sulphanilamide and Chromium. The ZnO nanostructures with a rod-like morphology exhibited an average crystallite size of 26 nm and an optical bandgap of 2.
