Designing 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 کاملManganese Ferrite Nanocomposite Modified Electrochemical Sensor for the Detection of Guanine and Uric Acid
Manganese ferrite nanoparticles were produced by applying the combustion technique using the manganese acetate and ferric nitrate as the starting material. Analytical techniques like FESEM and TEM were utilized to characterize the synthesized materials. The typical size was observed in the range of 12 to 14 nm with a cubic structure. The synthesized material was used as an electrochemical senso...
متن کاملQuantitative label-free RNA detection using surface-enhanced Raman spectroscopy.
Surface-Enhanced Raman Spectroscopy (SERS) was performed to detect label-free RNA. We defined conditions which make it possible to probe the four bases of RNA, in single strands of polyadenosine (pA), polyuridine (pU), polycytosine (pC) and polyguanosine (pG). We therefore present below a quantitative analysis of mixtures of non-hybridized single strands, based on the deconvolution of the SERS ...
متن کاملBiopatterning for label-free detection.
We present a biopatterning technique suitable for applications which demand a high degree of surface cleanliness, such as immobilization of biological recognition elements onto label-free biosensors. In the case of label-free biosensing, the mechanism of signal transduction is based on surface bound matter, making them highly sensitive to surface contamination including residues left during the...
