Dear Editor,

With the increased number of COVID-19 cases worldwide, the importance of a more efficient screening and diagnostic tool is a high priority for all major scientists working in medicine and bioengineering. However, currently, we have two major tests used in most countries – rapid antigen-antibody and reverse transcription-polymerase chain reaction (RT-PCR) – with the latter being the most effective among the two. In addition, the time required for the test results is very long, which makes controlling disease spread difficult and tedious. Low-cost diagnosis and rapid screening are the two most important criteria to ensure a particular screening method can be efficient and improves the time taken for each screening.[1] Despite the COVID-19 disease being present for more than a year, there is no rapid, low-cost, single-unit, and handheld device with the integrated function of detection and amplification. As a result, we must depend heavily on a centralized laboratory with complex machines and a specialized workforce to detect COVID-19.

There is a new technology, which scientists have been working on for some time now, called the TriSilix chip. It checks all requirements of being an effective and faster screening tool; if the research is finished and approved by respective organizations, it might be the next major advancement in testing pathogen-based diseases. TriSilix chip is a disposable, low-cost, silicon-based transducer, and its work is based on a process that involves amplification and electrochemical detection of pathogen-specific sequences in the patient's nucleic acid (NA).[2] NAs are the best way to detect pathogens, and many successful testing methods use the same formula to use NA to detect a specific pathogen; PCR and loop-mediated isothermal amplification (LAMP) use the same technique. NAs can be amplified and make it easy to detect pathogens; NA testing and reagents can be produced faster and in large amounts.[3]

It is essential to make testing cheaper, affordable, and accessible to the public, especially for people in the rural areas of low-income countries, where the clinics are generally far away from their homes. It will be expensive to travel long distances to get medical help. This chip can do wonders if it is made available to patients, as it can also be used to detect and monitor infections, such as urinary tract infections, which often recur despite the use of antibiotics.

Therefore, this article focused on differentiating between the other tests, such as RT-PCR, LAMP, and this new innovative method, TriSilix, a PCR-like lab-on-a-chip. Its functioning and its impact on the world as a testing device are what make it better.
