Many allergens on smartphones |

“Smartphones showed elevated and variable levels of β-D-glucans and endotoxin. Cat and dog allergens have also been found on pet owners’ smartphones,” said Hana Ruranová at the American Annual Allergology Conference. β-D-glucans are found in the cell walls of fungi and are an indication of the presence of problematic fungi. Endotoxins can cause severe inflammation and come from bacteria.

Prof. Dr. Peter Thorne of the University of Iowa concluded from the results: “If you suffer from allergies or asthma, you should consider cleaning your smartphone more often to minimize exposure to these allergens and asthma triggers.” The research team also offers tips on what to do with : It was found that a combination of chlorhexidine and cetylpyridinium works best to remove β-D-glucans and endotoxins from the device. A combination of benzyl benzoate and tannic acids worked best against cat and dog allergens.

The researchers created mock-ups of phones similar in size and finish to smartphones, which 15 volunteers took and used to simulate using a smartphone. Using electrostatic wipes, they sampled the “phones” to test for known allergens, β-D-glucans and endotoxins.
