Woven Electroanalytical Biosensor for Nucleic Acid Amplification Tests

چکیده
Fiber-based biosensors enable a new approach in analytical diagnostic devices. The majority of textile-based biosensors, however, rely on colorimetric detection. Here woven biosensor that integrates microfluidics structures combination with an electroanalytical readout based thiol-self-assembled monolayer (SAM) for Nucleic Acid Amplification Testing, NAATs is shown. Two types fiber-based electrodes are systematically characterized: pure gold microwires (bond wire) and off-the-shelf plasma gold-coated polyester multifilament threads to evaluate their potential form SAMs surface electrochemical performance textile. A DNA (E-DNA) sensor using SAM-based stem-loop probe-modified microwire fabricated. These sensors can specifically detect unpurified, isothermally amplified genomic Staphylococcus epidermidis (10 copies/µL) by recombinase polymerase amplification (RPA). This work demonstrates have the integrating being employed as automated, sample-to-answer devices point-of-care (POC) diagnostics.

Nucleic acid amplification tests for the diagnosis of pneumonia.
Molecular diagnostic techniques, such as polymerase chain reaction (PCR), are promising tools for the rapid etiological diagnosis of pneumonia. PCR offers potential advantages over conventional tests for the detection of Mycoplasma pneumoniae, Legionella species, and Chlamydia pneumoniae. For pneumococcal pneumonia in adults, PCR adds little to existing diagnostic tests and is unable to disting...
متن کاملNucleic Acid amplification tests for diagnosis of Bordetella infections.
The global epidemiology of pertussis has recently been reviewed (12, 15). Bordetella pertussis continues to circulate even in populations where high vaccination coverage of infants and children is achieved (15, 23), because the protection after natural infection wanes after 10 to 15 years and protection after vaccination lasts for 6 to 10 years (15). A significant increase of pertussis cases wa...
متن کاملTowards improved accuracy of Bordetella pertussis nucleic acid amplification tests.
In many clinical microbiology laboratories, nucleic acid amplification tests such as PCR have become the routine methods for the diagnosis of pertussis. While PCR has greatly increased the ability of laboratories to detect Bordetella pertussis infections, it has also been associated with false-positive results that can, given the tendency of B. pertussis to cause outbreaks, result in unnecessar...

Abstract Background and Objective: Culture, microscopic method is a gold standard method for identification of Lishmania parasite. The use of Molecular methods such as RT- PCR compared to microscopic methods has a higher sensitivity and specificity however, it is not widely used due to its expensive equipment and the time requested. The use of nucleic acid sequence based amplification (NASBA) ...
