Abstract
Microfluidic devices to efficiently remove particulate matter (PM) in air are provided, as are methods of fabricating and using the same. A device can include a channel having a structure configured to generate chaotic advective flow in air within the channel. The channel structure can include a plurality of SHMs disposed within the channel, where each SHM comprises a plurality of grooves each having a width of 200 μm or less and a spacing between each groove of 200 μm or less. The plurality of SHMs can be configured to introduce microvortices in air flow within the channel.
