Tip-enhanced Raman spectroscopic detection of aptamers
Single molecule detection, sequencing and conformational mapping of aptamers are important for improving medical and biosensing technologies and for better understanding of biological processes at the molecular level. We obtain vibrational signals of single aptamers immobilized on gold substrates using tip-enhanced Raman spectroscopy (TERS). We compare topographic and optical signals and invest...
متن کاملAptamers for respiratory syncytial virus detection
The identification of the infectious agents is pivotal for appropriate care of patients with viral diseases. Current viral diagnostics rely on selective detection of viral nucleic acid or protein components. In general, detection of proteins rather than nucleic acids is technically more suitable for rapid tests. However, protein-based virus identification methods depend on antibodies limiting t...
متن کاملProtein Detection by Nanopores Equipped with Aptamers
Protein nanopores have been used as stochastic sensors for the detection of analytes that range from small molecules to proteins. In this approach, individual analyte molecules modulate the ionic current flowing through a single nanopore. Here, a new type of stochastic sensor based on an αHL pore modified with an aptamer is described. The aptamer is bound to the pore by hybridization to an olig...
متن کاملAptamers Based Biosensors for Disease Detection
In the fabrication of biosensor, biorecognition elements or bioreceptorplay an important role. Bioreceptor is a biological molecular species (e.g. antibody, enzyme or nucleic acid) or a living biological system (e.g. cells, tissues or whole organisms) that has capability to recognize a target or substrate (analyte) molecules [1]. Bio-recognition elements have unique profile that helps in provid...
متن کاملNanobioprobe mediated DNA aptamers for explosive detection.
Specific nucleic acid aptamers using the microtiter plate based modified SELEX method against explosive trinitrotoluene are reported. Efficient partitioning of dsDNA was carried out using streptavidin labeled gold nanoprobes for the selection of specific aptamers. The selected binders having an affinity of ~10(-7) M were used in the newly developed electrochemical aptasensor, exhibiting a detec...
