Key points from article :
Scientists at at Soochow University in China created inhalable nanoparticles to deliver antibiotics deep inside the lungs.
They tested them on 6 mice with COPD symptoms and saw reduced inflammation and improved lung function.
COPD narrows and stiffens airways, making breathing difficult and attracting harmful bacteria.
Mucus traps medication, but these nanoparticles have a special coating to penetrate it.
The coating releases the antibiotic in response to the slightly acidic environment in the lungs.
This targeted delivery approach could be a promising new way to treat COPD infections.
