Are there good sensors for pollen? | element14 | …

20-06-2021· Some claim their PM10 sensors can detect pollen- not true (or misleading at best)! Allergy-causing pollen is 20 microns - 200 microns (Grass pollen being the most common cause of hayfever at 20 microns) All air purifier "auto" modes work with a sensor which is useless during hayfever season when it needs a PM30 sensor.

Detection and quantification of four viruses in …

Pollen transmitted viruses require accurate detection and identification to minimize the risk of spread through the global import and export of pollen. Therefore in this study we developed RT-qPCR assays for the detection of Cherry leaf roll virus (CLRV), Prune dwarf virus (PDV), Prunus necrotic ringspot virus (PNRSV), and Cherry virus A (CVA), four viruses that infect pollen of Prunus species.
