The pH-sensitive component encloses an antibiotic which is released to the wound upon infection by a microorganism at the wound site, and/or encloses a pH indicator. The antibiotic release is triggered by the microorganism's production of CO2 at the wound site which forms carbonic acid, lowers the pH at the pH sensitive components, and thus results in rupture of the liposome.
