Webb4 jan. 2024 · Once the aerosol droplets are inhaled, the nanoparticles contained within each droplet enter the cells and instruct it to make a particular protein from mRNA,” Patel says. The researchers found that 24 hours after the mice inhaled the mRNA, lung cells were producing the bioluminescent protein. WebbLarge porous particles (LPPs), characterized by geometric sizes greater than 5mm and mass den-sities less than 0.4g/cm3, have achieved recent popularity for drug delivery to the lungs for both local and systemic applications.1,2 A principal advantage of LPPs relative to conventional inhaled therapeutic aerosol particles is their aerosolization WebbNanoparticle aerosol production and exposure system.
