Biosensors consist of a molecular recognition element and a transducer. Since the first
biosensor was developed by Updike and Hicks [1] many biosensors and their associated …

Aptamers are artificial nucleic acid ligands that can be generated against amino acids,
drugs, proteins and other molecules. They are isolated from complex libraries of synthetic …

Two biosensors have been constructed using an RNA aptamer as biorecognition element.
The aptamer, specific for HIV-1 Tat protein, has been immobilised on the gold surface of …

The in vitro selection of combinatorial libraries of RNA/DNA, has allowed the identification of
specific nucleic acids (aptamers) which bind to a wide range of target molecules with high …

We have assembled references of 700 articles published in 2001 that describe work
performed using commercially available optical biosensors. To illustrate the technology's …

'Locked nucleic acids'(LNAs) are sugar modified nucleic acids containing the 2′-O-4′ C-
methylene-β-d-ribofuranoses. The substitution of RNAs with LNAs leads to an enhanced …

In this work we present an impedimetric detection system for DNA‐ligand interactions. The
sensor system consists of thiol‐modified single‐stranded DNA chemisorbed to gold …

We have studied the electrochemical and optical properties of europium; a rare-earth ion
functionalized ordered hybrid mesoporous silica material and evaluated its potential …

Artificial assemblies consisting of the cationic cytochrome c (cyt c) and double-stranded DNA
are interesting for the field of biohybrid systems because of the high electro-activity of the …

Conventional analysis of molecular interactions by surface plasmon resonance is achieved
by the observation of optical density changes due to analyte binding to the ligand on the …
