Most people don't enjoy getting shots for treatments or vaccines. So, researchers are working to create more medicines, such as those made from messenger RNA (mRNA), that can be sprayed and inhaled. A study reports steps toward making inhalable mRNA medicines a possibility. Researchers outline their improved lipid-polymer nanoparticle for holding mRNA that is stable when nebulized and successfully delivers aerosols (liquid droplets) in mice's lungs.
