However, this strategy faces many challenges, including instability in the gastrointestinal (GI) tract, insufficient bioavailability, low tumor targeting, and severe adverse effects.
But the present devices are not ideal enough to meet the application needs because the problems of insufficient capture, low purity, and narrow detection spectrum still need to be addressed.
Conventional PDT efficacy is restricted by insufficient selectivity, low solubility of photosensitizers, and limited penetration depth of the 630-nm laser light, which reduces the PDT efficacy for tumors located in deeper tissues compared with those at the body surface.
