New Rapid and Environmentally Friendly Test Developed for COVID-19 Detection
An American research team has announced the successful development of a rapid and low-cost test for detecting the “Covid-19” epidemic. The test, which is based on environmentally friendly materials, aims to provide a more sustainable alternative to the widely used polymerase chain reaction (PCR) test.
While the PCR test is considered the “gold standard” for Covid-19 diagnostics, it generates significant medical waste, including metals, plastics, and other environmentally unfriendly materials. Additionally, the PCR test requires specialized equipment and labor, leading to increased costs and longer turnaround times for results.
According to an analysis by the World Health Organization, over 140 million PCR test kits have been conducted since February 2022, resulting in 2,600 tons of non-infectious waste such as plastic and 731,000 liters of chemical waste. This environmental impact highlights the need for alternative testing methods that are rapid, affordable, and sustainable.
Cesar de la Fuente, an assistant professor at the University of Pennsylvania, and his team have been working to develop such tests since the outbreak of the Covid-19 pandemic. Their latest achievement is a new test based on a nano-sized form of a substance called “bacterial cellulose,” which has garnered significant research interest in recent years.
Similar to vegetable cellulose, bacterial cellulose is produced by certain types of bacteria and can be used as a material for biosensors. It is non-toxic, naturally biodegradable, and cost-effective, making it an ideal candidate for a sustainable Covid-19 test. Currently, the test costs less than $4 per test to produce.
In clinical trials, the test has proven highly accurate, correctly identifying multiple variants of Covid-19 in less than 10 minutes. This rapid detection capability paves the way for efficient containment and treatment strategies to curb the spread of the virus.
De la Fuente emphasized the importance of responsible innovation and considering the environmental consequences of new technologies. He stated, “When we invent a new technology, it is our responsibility to think about the consequences on the planet and find ways to mitigate the environmental impact.”
In addition to its benefits for Covid-19 testing, de la Fuente envisions expanding the use of similar green alternatives for diagnostic tests on a large scale. He believes there is a need for biodegradable diagnostic tests and plans to improve this technology further while exploring its potential for other emerging pathogens in anticipation of future epidemics.
The development of this rapid and environmentally friendly Covid-19 test brings hope not only for combatting the current pandemic but also for advancing sustainable healthcare practices for the future.]
