Fluorescent silver nanoclusters as DNA probes.
Nanoscale, 2013Fluorescent silver nanoclusters (few atoms, quantum sized) have attracted much attention as promising substitutes for conventional fluorophores. Due to their unique environmental sensitivities, new fluorescent probes have been developed based on silver ...

Absolute and direct microRNA quantification using DNA-gold nanoparticle probes.
Journal of the American Chemical Society, 2014DNA-gold nanoparticle probes are implemented in a simple strategy for direct microRNA (miRNA) quantification. Fluorescently labeled DNA-probe strands are immobilized on PEGylated gold nanoparticles (AuNPs).

Characterization of DNA Probes Immobilized on Gold Surfaces
, 1997We have characterized thiol-derivatized, single-stranded DNA (5‘-HS-(CH2)6-CAC GAC GTT GTA AAA CGA CGG CCA G-3‘, abbreviated HS-ssDNA) attached to gold via a sulfur−gold linkage using X-ray photoelectron spectroscopy (XPS), ellipsometry, and 32P ...

Diagnostic Applications of DNA Probes [PDF]
Infection Control & Hospital Epidemiology, 1991 The use of recombinant DNA technology to develop specific molecular (usually DNA) probes has provided medical and veterinary diagnostic laboratories with powerful new tools to enhance the diagnosis of infectious diseases, genetic disorders, and malignancies, as well as more sensitive and specific means to accomplish such tasks as tissue typing and ...

Probing RNA Translocases with DNA
2014For some helicases, it is possible to investigate RNA translocase activity on DNA substrates because the enzyme acts on both substrates. Potassium permanganate (KMnO4) footprinting is a method used to chemically probe the conformation of DNA as well as the binding of proteins.

Design aspects of bright red emissive silver nanoclusters/DNA probes for microRNA detection.
ACS Nano, 2012The influence of the nucleic acid secondary structure on the fast (1 h) formation of bright red emissive silver nanoclusters (AgNCs) in a DNA sequence (DNA-12nt-RED-160), designed for the detection of a microRNA sequence (RNA-miR160), was investigated ...

Publisher Summary This chapter discusses the structure of DNA by enzymes and chemicals probing. Enzyme and chemical probing experiments have generated important insight into a number of altered DNA structures, including cruciform structures, left-handed Z-DNA, A tract-containing curved DNA, H-triplexes, G-tetrad structures, and parallel-stranded DNA,
