Nanoparticles could boost effectiveness and reduce side effects of allergy shots
The researchers designed a new type of nanocarrier based on the biocompatible molecule poly(ethylene glycol), or PEG, that releases its cargo only in targeted immune cells. The nanocarrier degrades when it encounters the acidic part of these cells, simultaneously releasing the allergen and getting rid of the packaging.
