Enhancing chemical signal transformation in lateral flow assays using aptamer-architectured plasmonic nanozymes and para-phenylenediamine.

The widespread adoption and commercialization of lateral flow assays (LFAs) for clinical diagnosis have been hindered by limitations in sensitivity, specificity, and the absence of quantitative data. To address these challenges, we developed aptamer-architectured gold nanoparticles as nanozymes that catalytically convert -phenylenediamine (PPD) into Bandrowski's base (BB), thereby amplifying signal strength and sensitivity. The physiochemical properties of the nanozymes were characterized and their specific binding efficiency was demonstrated using experimental studies.

Clinical, Imaging, and Atrial Cardiopathy Markers in Ischemic Stroke Subtypes - Clues to a Cardioembolic Source.

Background And Objectives: Cryptogenic strokes account for 20%-25% of all ischemic strokes. Although atrial cardiopathy markers are more prevalent in the cryptogenic embolic stroke of undetermined source (ESUS) subgroup than in the nonembolic stroke subgroup, the utility of individual parameters in predicting cardioembolic sources needs to be studied further. We studied the clinical, imaging, and atrial cardiopathy markers in three ischemic stroke subtypes - large artery atherosclerosis (LAA), cardioembolism (CE), and cryptogenic ESUS - and their role in predicting the source of CE.

Identification of benzimidazole-6-carboxamide based inhibitors of secretory glutaminyl cyclase for the treatment of Alzheimer's disease.

The formation of the pyroglutamate variant of amyloid beta (pGlu-Aβ), which is extremely hydrophobic, rapidly aggregating, and highly neurotoxic, is mediated by the action of secretory glutaminyl cyclase (sQC). The pGlu-Aβ often acts as a seed for the aggregation of the full length Aβ and contributes to the overall load of Aβ plaques in Alzheimer's disease (AD). Therefore, inhibiting sQC is a potential approach to limit the formation of pGlu-Aβ and to modify the progression of AD.

Mechanistic insights into the competitive inhibition of enzyme-mimetic activity of gold nanoparticles for dual mode colorimetric and fluorescence detection of biothiols.

In this work, the interaction behaviour of gold nanoparticles (AuNPs) with o-phenylenediamine (OPD) was studied to ascertain the nanozyme-substrate interaction. The UV-Vis absorption, high-resolution transmission electron microscopy and zeta potential analysis revealed that the electron-rich nitrogen atoms in OPD showed a stronger affinity toward electron-deficient surface, indicating a stronger interaction between nanozyme and substrate molecules. Subsequently, under optimum conditions, AuNPs are used as nanozyme to catalyze the oxidation of OPD in the presence of HO.
