Sure, thanks your question, microfluidics enables us to do lots of different things with tiny volumes/amounts of fluids which are applied to lots of different fields from bioengineering to catalysis. By having micro-sized channels, we can incorporate them into devices to enable us to work on much smaller scales. This helps us investigate fundamental questions such as how a fluid flows at the microscale (around the thickness of a single human hair) but also enables high-throughput screening and manufacturing through multiplexing (putting lots of devices together) microfluidic devices. Some vaccines are manufactured through high-throughput microfluidics. Microfluidics can give us the ability to have lab-on-chips, where we miniaturise all the components, we can carry out in a lab onto one chip.
