Fig. 1From: Exposure to positively- and negatively-charged plasma cluster ions impairs IgE-binding capacity of indoor cat and fungal allergensCylindrical apparatus for PC-ions exposure. PC-ions were generated in four Plasma cluster™ devices (shown as gray boxes) that were placed inside of wall of the apparatus. PC-ions were emitted from the devices and filled the apparatus at 2.5 × 104 ions/cm3. A “mist” solution containing allergen was generated from a nebulizer located on the top of the apparatus, which is shown in a box with horizontal stripe. The solution was shed at 2.5 L/min (flow rate) and 3.3 m/s (linear velocity). A petri dish was placed beneath the apparatus to collect the PC-ions- or sham-treated allergen solutionBack to article page
