Diagnostic Devices for Isothermal Nucleic Acid Amplification
Since the development of the polymerase chain reaction (PCR) technique, genomic information has been retrievable from lesser amounts of DNA than previously possible. PCR-based amplifications require high-precision instruments to perform temperature cycling reactions; further, they are cumbersome for routine clinical use. However, the use of isothermal approaches can eliminate many complications...
متن کاملA Simple, Low-Cost Platform for Real-Time Isothermal Nucleic Acid Amplification
Advances in microfluidics and the introduction of isothermal nucleic acid amplification assays have resulted in a range of solutions for nucleic acid amplification tests suited for point of care and field use. However, miniaturisation of instrumentation for such assays has not seen such rapid advances and fluorescence based assays still depend on complex, bulky and expensive optics such as fluo...
متن کاملMicrofluidic devices for nucleic acid (NA) isolation, isothermal NA amplification, and real-time detection.
Molecular (nucleic acid)-based diagnostics tests have many advantages over immunoassays, particularly with regard to sensitivity and specificity. Most on-site diagnostic tests, however, are immunoassay-based because conventional nucleic acid-based tests (NATs) require extensive sample processing, trained operators, and specialized equipment. To make NATs more convenient, especially for point-of...
متن کاملHandheld isothermal amplification and electrochemical detection of DNA in resource-limited settings.
This paper demonstrates a new method for electrochemical detection of specific sequences of DNA present in trace amounts in serum or blood. This method is designed for use at the point-of-care (particularly in resource-limited settings). By combining recombinase polymerase amplification (RPA)- an isothermal alternative to the polymerase chain reaction - with an electroactive mediator, this elec...
متن کاملInnovative Approaches to Clinical Data Management in Resource Limited Settings Using Open-Source Technologies
The primary objective of clinical data management (CDM) is to provide highquality, reliable data for reporting randomized controlled trials (RCTs) in line with good clinical practice (GCP) requirements. For treatment trials of neglected tropical diseases (NTDs) in endemic countries, CDM systems need to be efficient and affordable. Challenges include poor infrastructure, license costs associated...
