Aptamer Sensors
In the last years, great progress has been accomplished in the development of aptamer sensors with different transducers. In order to improve the sensitivity of these biosensors, several methodologies have been employed. In this Special Issue, the state of art and the future trends in the field of aptamer sensors have been explored.
متن کاملAptamer functionalized microcantilever sensors for cocaine detection.
A cocaine-specific aptamer was used as a receptor molecule in a microcantilever-based surface stress sensor for detection of cocaine molecules. An interferometric technique that relies on measuring differential displacement between two microcantilevers (a sensing/reference pair) was utilized to measure the cocaine/aptamer binding induced surface stress changes. Sensing experiments were performe...
متن کاملAptamer Sensors Combined with Enzymes for Highly Sensitive Detection
Diagnostics have taken on a larger role in patient care, with diagnostics for point-of-care testing (POCT) having greatly expanded during the last two decades. The expectation is that POCT will continue to grow because it can help to expand personalized therapy and theranostics, which will provide the right medicine to the right person, with the right dosage at the right time. For POCT, it will...
متن کاملAdvances in Clinical Diagnosis through Electrochemical Aptamer Sensors
Volume 5 • Issue 3 • 2013 Aptamers are oligonucleotides, such as ribonucleic acid (RNA) and single-strand deoxyribonucleic acid (ssDNA) or a peptide molecule that can bind with a specific target molecule with high affinity and specificity which is due to the formation of specific three-dimensional structures. Since the discovery of aptamers, scientists have used aptamer in the fabrication of va...
متن کاملDNA module platform for developing colorimetric aptamer sensors.
Here we present a DNA module platform for developing simple aptamer sensors based on a microarray format combined with secondary structure prediction in silico. The platform comprises four parts: (i) aptamer, (ii) joint module, (iii) terminal stem, and (iv) a DNAzyme that catalyzes a redox reaction controlled by a structural change induced by aptamer/target binding. First, we developed a joint ...
