Massively multiplexed nucleic acid detection with Cas13 | Nature
Heat maps indicate background-subtracted fluorescence after 1 h (for H1¨CH16 discrimination) or 3 h (for N1¨CN9 discrimination) of Cas13 detection. In b ¨C d, synthetic targets were used at 10 ...
SHERLOCK: nucleic acid detection with CRISPR nucleases - Nature
Rapid nucleic acid detection is an important part of many applications in human health and biotechnology, including the sensing of infectious agents, agricultural pathogens, or circulating DNA or ...
RT-nestRPA is a new technology for the rapid and sensitive ...
Therefore, some scientists suggested that RT-qPCR should not be the sole technique used to detect SARS-CoV-2 nucleic acids [27]. To develop a highly sensitive and rapid nucleic acid detection technology, we conceptualized nestRPA based on RPA platform and applied it to the detection of SARS-CoV-2 [4]. For RNA pathogens, such as SARS-CoV-2, we ...
Designing sensitive viral diagnostics with machine learning
Abstract. Design of nucleic acid-based viral diagnostics typically follows heuristic rules and, to contend with viral variation, focuses on a genome¡¯s conserved regions. A design process could ...
Ultrafast Nucleic Acid Detection Equipment with Silicon-Based ...
Recently, infectious diseases, such as COVID-19, monkeypox, and Ebola, are plaguing human beings. Rapid and accurate diagnosis methods are required to preclude the spread of diseases. In this paper, an ultrafast polymerase chain reaction (PCR) equipment is designed to detect virus. The equipment consists of a silicon-based PCR chip, a thermocycling module, an optical detection module, and a ...
Nucleic Acids Analytical Methods for Viral Infection ...
In fact, the possibility to specifically separate and extract few copies of viral genomes among more abundant copies of human or animal nucleic acid in a typical biological sample (blood, urine, saliva) has increased the amount of template available for the subsequent amplification and detection steps, providing an enhancement of the analytical ...
Nucleic Acid Amplification Tests (NAATs) | CDC
A Nucleic Acid Amplification Test, or NAAT, is a type of viral diagnostic test for SARS-CoV-2, the virus that causes COVID-19. NAATs detect genetic material (nucleic acids). NAATs for SARS-CoV-2 specifically identify the RNA (ribonucleic acid) sequences that comprise the genetic material of the virus. NAATs for SARS-CoV-2 test specimens from ...
New Type Viral Nucleic Acid Detection Reagent Filling Machine
New coronavirus infected pneumonia laboratory Technical Guide to Detection. The nucleic acid detection methods in this guide are mainly for open read box 1a/b (open reading frame 1ab,ORF1ab) in the genome of the new coronavirus and nucleocapsidprotein, N.
Recent advances in PCR-free nucleic acid detection for SARS ...
Polymerase chain reaction (PCR) of viral nucleic acids has been the gold standard method for SARS-COV-2 detection, which, however, generally requires sophisticated facilities and laboratory space, and is time consuming. This review presents recent advances in PCR-free nucleic acid detection methods for SARS-CoV-2, including emerging methods of ...
Recent advancements in nucleic acid detection with ...
To fully integrate nucleic acid extraction, amplification and detection on a microfluidic system and to enable the detection of five high-risk HPV indicators, researchers [44] used chitosan-modified magnetic microspheres for pH-induced nucleic acid extraction and integrated this approach into a centrifugal microfluidic chip (Fig. 2 A). The ...
