Spray-drying nanoparticles is not only interesting to create supraparticles. It is also a way to generate solid-filled aerosols. The process is a model to what happens when humans cough or sneeze virus particles such as SARS-CoV-2. Using harmless fluorescent silica-based virus analogues, it can easily be evaluated how well different mask materials prevent particle penetration using the process of spray-drying. Our work, investigating this, was just accepted by Advanced Materials Technologies. If you are interested you can give it a read here.
