Instrument for Label-Free Detection of Noncoding RNAs
We set up a label-free direct binding assay for the detection of noncoding RNAs. The assay is based on nanomechanical cantilever arrays for the detection of surface stress induced by immobilized biomolecules and their interaction partners. We used various means to significantly reduce the drift of the cantilever readout that was a prominent feature in experiments with readout in stationary flui...
متن کاملDesigning a Label Free Aptasensor for Detection of Methamphetamine
A label-free electrochemical nucleic acid aptasensor for the detection of methamphetamine (MA) by the immobilization of thiolated self-assembled DNA sequences on a gold nanoparticles-chitosan modified electrode is constructed. When MA was complexed specifically to the aptamer, the configuration of the nucleic acid aptamer switched to a locked structure and the interface of the biosensor changed...
متن کاملAngular spectrum detection instrument for label-free photonic crystal sensors.
An angular spectrum analysis system was demonstrated to monitor the optical resonant mode of a photonic crystal (PC) sensor comprised of a one-dimensional grating structure. Exposed to solutions with different refractive indices or adsorbed with biomaterials, the PC sensor exhibited changes of the optical resonant modes. The developed detection system utilized a focused laser beam to detect shi...

متن کاملnoncoding rnas and cancer
the eukaryotic complexity involves the expression and regulation of genes via rna-dna, rna-rna, dna-protein and rna-protein interactions. recently, the role of rna molecules in the regulation of genes in higher organisms has become more evident, especially with the discovery that about 97% of the transcriptional output in higher organisms are represented as noncoding rnas: rrna, snornas, trna, ...
