At present, real-time polymerase chain reaction (RT-PCR) assay is considered the gold standard for the diagnosis of SARS-CoV-2 infection. RT-PCR is a nuclear-derived method for detecting the presence ...

The COVID-19 pandemic has highlighted the need for rapid and accurate nucleic acid detection at the point of care. To meet this need, scientists from the Suzhou Institute of Biomedical Engineering and ...

Immunosensors are widely used in immunoassays to detect antigens. One such immunosensor is a quenchbody (Q-body), which contains a modified antibody fragment with a quenched fluorescent dye. When an ...

Dynamics Author: Howard Goldner During the past few decades, fluorescence spectroscopy has developed into an integral technique in many scientific disciplines. In the life sciences, it is implemented ...

A new method that can rapidly determine whether a virus is infectious or non-infectious could revolutionize the response to future pandemics, researchers report. A new method that can rapidly ...

Conventional fluorescence microscopy provides poor quantitative information of the sample because it only captures fluorescence intensity, which changes frequently and depends on external factors. Now ...

Immunoassays are measurement procedures that use immune-based reagents to generate a detectable signal, allowing scientists to quantify biological processes. Scientists perform immunoassays to measure ...

The measurement of specific molecules in serum and plasma is essential in the diagnosis, treatment and management of many diseases. Traditional methods have used single assay techniques, whereby only ...
