Aptamer-based cell imaging reagents capable of fluorescence switching.

We describe an aptamer-conjugated polydiacetylene imaging probe (ACP) that shows highly specific fluorescence switching upon binding to epithelial cancer cells that overexpress the tumor biomarker protein EpCAM (epithelial cell adhesion molecule) on their surface.

Bioluminescence Assisted Switching and Fluorescence Imaging (BASFI)

Förster resonance energy transfer (FRET) and bioluminescence resonance energy transfer (BRET) are two major biophysical techniques for studying nanometerscale motion dynamics within living cells. Both techniques read photoemission from the transient RET-excited acceptor, which makes RET and detection processes inseparable. We here report a novel hybrid strategy, bioluminescence assisted switchi...

Current progress of aptamer-based molecular imaging.

Aptamers, single-stranded oligonucleotides, are an important class of molecular targeting ligand. Since their discovery, aptamers have been rapidly translated into clinical practice. They have been approved as therapeutics and molecular diagnostics. Aptamers also possess several properties that make them uniquely suited to molecular imaging. This review aims to provide an overview of aptamers' ...

High-Throughput Bead-Based Identification of Structure-Switching Aptamer Beacons

We describe a new platform to identify structure-switching DNA beacon aptamers, which detect small molecules in a specific manner. By clonally amplifying a DNA library designed to fluoresce in response to binding events onto microbeads, aptamer beacons can be selected by stringent fluorescence-assisted sorting. We validated this method by isolating known and novel anti-steroid aptamers from two...

Time-resolved fluorescence aptamer-based sandwich assay for thrombin detection.

In the present study, the authors report a novel sensitive method for the detection of thrombin using time-resolved fluorescence sensing platform based on two different thrombin aptamers. The thrombin 15-mer aptamer as a capture probe was covalently attached to the surface of glass slide, and the thrombin 29-mer aptamer was fluorescently labeled as a detection probe. A bifunctional europium com...
