Photonic porous silicon as a pH sensor [PDF]
Nanoscale Research Letters, 2014 Chronic wounds do not heal within 3 months, and during the lengthy healing process, the wound is invariably exposed to bacteria, which can colonize the wound bed and form biofilms. This alters the wound metabolism and brings about a change of pH.
