Noncompetitive Determination of Small Analytes by Sandwich-Type Lateral Flow Assay Based on an Aptamer Kissing Complex.

Here, we present the proof-of-concept of a lateral flow assay (LFA) that is capable of detecting small-molecule targets in a noncompetitive manner by deploying a sandwich-type format based on the aptamer kissing complex (AKC) strategy. A fluorescently labeled hairpin aptamer served as the signaling agent, while a specific RNA hairpin grafted onto the strip served as the capture element. The hairpin aptamer switched from an unfolded to a folded form in the presence of the target, resulting in kissing interactions between the loops of the reporter and the capture agents.

Acridone derivatives, which have been shown to have and activity against spp, inhibit proliferation at picomolar concentrations. Using enzymatic assays, we show that acridones inhibit both cytochrome and dihydroorotate dehydrogenase and identify acridones that bind preferentially to the Q site of cytochrome . We identify acridones that have efficacy in a murine model of systemic toxoplasmosis.

DNAzymes as key components of biosensing systems for the detection of biological targets.

DNAzymes are synthetic functional nucleic acids that have found widespread use in biosensing applications both for molecular recognition and signal generation. Two classes of DNAzymes have proved particularly effective for use in proof-of-concept biosensing systems, namely RNA-cleaving DNAzymes (RCDs) and peroxidase mimicking DNAzymes (PMDs). RCDs catalyze the site-specific cleavage reaction of an RNA dinucleotide junction, generating two cleavage fragments.

Exploring the Unique Contrast Properties of Aptamer-Gadolinium Conjugates in Magnetic Resonance Imaging for Targeted Imaging of Thrombi.

: An important clinical question in the determination of the extent of thrombosis-related vascular conditions is the identification of blood clot location. Fibrin is a major molecular constituent of blood clots and can, therefore, be utilized in molecular imaging. In this proof-of-concept study, we sought to prepare a fibrin-targeting magnetic resonance imaging contrast agent, using a Gd(III)-loaded fibrinogen aptamer (FA) chelate conjugate (Gd(III)-NOTA-FA) (NOTA = 1,4,7-triazacyclononane-1,4,7-triacetic acid), to endow the ability to specifically accumulate at the location of blood clots, thereby enhancing contrast capabilities.
