Electrochemical aptamer-based biosensors as potential tools for clinical diagnostics
Aptamers are single-stranded DNA and RNA sequences that belong to the group of “functional nucleic acids”, which exhibit both catalytic and receptor properties. Aptamers change their spatial conformation upon binding to a target analyte, and so far more than 200 sequences selective for large variety of molecules such as metal ions, organic dyes, proteins and bacteria cells have been identified....
متن کاملModified peptide monolayer binding His-tagged biomolecules for small ligand screening with SPR biosensors.
A peptide self-assembled monolayer (SAM) was designed to bind His-tagged biomolecules for surface plasmon resonance (SPR) bioanalysis, which was applied for the determination of K(d) for small ligand screening against CD36. Nonspecific adsorption could be minimized using penta- and hexa-peptide monolayers. In particular, monolayers consisting of 3-mercaptopropionyl-leucinyl-histidinyl-aspartyl-...
متن کاملChemically modified diamondoids as biosensors for DNA.
Understanding the interaction of biological molecules with materials is essential in view of the novel potential applications arising when these two are combined. To this end, we investigate the interaction of DNA with diamondoids, a broad family of tiny hydrogen-terminated diamond clusters with high technological potential. We model this interaction through quantum-mechanical computer simulati...
متن کاملLabel-free electrochemical biosensors for food and drug application
In food sector, there is a huge demand for rapid, reliable, user & eco-friendly biosensors to analyse the quality and safety of food products. Biosensor based methodology depends upon the recognition of a specific antigens or receptors by corresponding antibodies, aptamers or high-affinity ligands. The first scientifically commercialised sensors were the electrochemical sensors used for the ana...
متن کاملAdvancement in electrochemical DNA-biosensors for GMOs detection: A review
Genetically modified organisms (GMOs) are plants or animals whose genetic make-up has been transformed by recombinant DNA technology, which has new features such as resistance to herbicides, virus and insect. Recently, genetic modification of food products has increased in order to reduce world poverty and hunger and increase food production However, the impact of GMOs on the human health is a ...
