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.
1
The handheld counter produced more consistent and realistic pollen counts than conventional liquid particle counters in controlled side-by-side vibration experiments
2
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
3
Airborne pollen from birch anthers declined exponentially with distance from the source, a dispersal curve the device mapped without any laboratory processing
