The COVID-19 pandemic has revived interest in wastewater testing, a technique capable of detecting infections before symptoms appear, thus aiding in early outbreak containment.
Cranfield University researchers developed an origami-inspired paper sensor for wastewater testing, providing a low-cost method to detect diseases without needing electricity or specialized equipment.
Using wastewater monitoring for public health gained traction during the pandemic, with universities and health institutes utilizing it effectively to catch outbreaks ahead of time.
The innovative paper test costs only $1 and could potentially be commercialized in the next two to three years, enhancing public health surveillance capabilities.
