Article Synopsis
- Paper-based biosensors are cost-effective and portable devices designed for the easy detection of biochemical substances, especially useful for point-of-care testing.
- Nucleic acid-based methods provide flexibility in detecting pathogens, and when combined with paper-based platforms, they enable accurate results in a non-laboratory setting.
- The review covers current technologies, examines challenges in integrating these systems, and suggests future research avenues to enhance paper-based biosensor development.
Article Synopsis
- The ongoing pandemic has significantly impacted the global economy, highlighting the importance of diagnostic testing in controlling virus spread and protecting public health.
- A new paper-based device using RT-LAMP allows for easy and visible detection of SARS-CoV-2 with just a simple heat source, making it suitable for use in low-resource settings.
- This testing platform is adaptable, enabling it to be reconfigured for various pathogens by changing primers, and it has potential applications in areas like food safety and animal diagnostics.
A paper-based colorimetric molecular test for SARS-CoV-2 in saliva.
Biosens Bioelectron X
December 2021
Article Synopsis
- A new paper-based device has been developed for detecting pathogen nucleic acids using a method called loop-mediated isothermal amplification (LAMP), providing visible color changes for easy identification.
- The device was specifically optimized to detect SARS-CoV-2 in human saliva within 60 minutes, achieving a high sensitivity of 97% and a specificity of 100%.
- It is designed with multiple reaction zones on special chromatography paper and can be adjusted to identify different pathogens by simply changing the LAMP primers used.
