Researchers showed that a pocket-sized air particle counter can quantify airborne pollen in real time, right in the field — no lab required. Tested on both buzz-pollinated and wind-pollinated flowers, it outperformed traditional methods and could also be used to track spores, seeds, and airborne pathogens.
The handheld counter produced more consistent and realistic pollen counts than conventional liquid particle counters in controlled side-by-side vibration experiments
High-speed video showed traditional methods miss substantial pollen because buzz-pollinated stamens release it in unpredictable directions — a directional bias the handheld device avoids by sampling the full surrounding air volume
Airborne pollen from birch anthers declined exponentially with distance from the source, a dispersal curve the device mapped without any laboratory processing
