Researchers develop novel intranasal mask to protect respiratory tract from viral aerosols https://medicalxpress.com/news/2023-12-intranasal-mask-respiratory-tract-viral.html
> To increase protection against viral aerosols, the researchers designed an intranasal mask (MV@GEL) that comprises a positively charged thermosensitive hydrogel and cell-derived microsized vesicles featuring viral receptors.
> "The intranasal mask can be sprayed into the nasal cavity at room temperature and quickly transforms from the liquid state to the gel state at body temperature. Inside the nasal cavity, the positively charged hydrogel can intercept the negatively charged viral aerosols that present in the airflow, while the receptor on the vesicles can interact with the virus that is released from viral aerosols to MV@GEL, thereafter mediating the entrapment of the virus for inactivation,"
