When you think of micro- or nanotechnology, you likely think of small electronics like your phone, a tiny robot or a microchip. But COVID-19 tests – which have proven to be central to controlling the pandemic – are also a form of miniaturized technology. Many COVID-19 tests can give results within hours without the need to send a sample to a lab, and most of these tests use an approach called microfluidics.
I am a professor of bioengineering and work with microfluidics for my research. Everything from pregnancy tests to glucose strips to inkjet printers to genetic tests rely on microfluidics. This technology, unbeknownst to many people, is everywhere and critical to many of the things that make the modern world go round.
