Folic acid-modified diatrizoic acid-linked dendrimer-entrapped gold nanoparticles as nanoprobes for targeted CT imaging of human cervical cancer

Specific detection of Shigella sonnei by enzyme-linked aptamer sedimentation assay

Development of potent new anti-Shigella agents for rapid and specific detection and treatment is of great importance. Aptamers, nucleic acid oligomers capable of specific binding to a wide range of non-nucleic acid targets, may be of value for this purpose. In the present study, we used a Systematic Evolution of Ligands by Exponential enrichment (SELEX) process to select DNA aptamers that b...

Synthesis and properties of a new type DNA dendrimer.

We have designed a new type of a DNA dendrimer which has rigid branched structure. The branching molecule was prepared from 1,3,5-tribromobenzene. The dendrimer unit, in which three oligonucleotide-chains, two molecules of T15 and one molecule of A15, linked to the branching molecule, was synthesized by an automated DNA synthesizer. The properties of the dendrimer unit and dendrimer formation b...

Protein expression monitoring can be a good tool to determine disease onset and progression, and is also used in drug discovery and investigational science (1–4). However, commonly used assays lack the sensitivity and specificity required for the detection of low-abundance proteins (5,6). Several signal amplification technologies have been designed and applied to protein detection assays, inclu...

Uses of Dendrimers for DNA Microarrays

Biosensors such as DNA microarrays and microchips are gaining an increasing importance in medicinal, forensic, and environmental analyses. Such devices are based on the detection of supramolecular interactions called hybridizations that occur between complementary oligonucleotides, one linked to a solid surface (the probe), and the other one to be analyzed (the target). This paper focuses on th...
