Abstract
Techniques for efficiently capturing targets, such as biological materials, within the air are described. A lightweight, portable device is configured to capture the targets without desiccation by flowing a mixture of air carrying the targets with liquid droplets through a nonlinear path in a partially enclosed interior of the device. For example, a method includes generating an impinging jet comprising a mixture of air, a target, and droplets. A baffle splits the impinging jet into a recirculation zone and coalesces a mixture of the target and the droplets onto an upper surface of the baffle. At least one channel receives the coalesced mixture and transports the coalesced mixture to a collection reservoir.
