Light-absorbing particles, known as photosensitizers, are located in plants and pets, including people. There are numerous photosensitizers, yet many are able to soak up a certain range of light wavelengths.
As soon as the photosensitizer is subjected to a light with a matching spectral range, it's transformed from its ground state right into an ecstatic singlet state. This enables it to move energy to molecular oxygen, creating singlet oxygen and totally free radicals that moderate cellular poisoning.
The Light
During therapy, a special light is beamed on the location where the photosensitizer was used. This light triggers the drug and damages cancer cells or precancerous cells that it has actually targeted.
The drugs that are utilized in photodynamic treatment have various absorption residential or commercial properties and several of them may take hours to leave typical cells yet stay much longer in cancer or precancer cells.

It is absorbed by the growth cells and triggered when exposed to light of a particular wavelength. This causes a sequence of photochemical reactions that generates responsive oxygen types (ROS) that damage growth tissue and eliminate cancer cells.
