Hypericin absorption
WebAlso introduced into the cell are means to chemically activate the energy donating chemical which photoactivates the photosensitizing chemical which then destroys the tumor or virus. The photosensitizing chemical is preferably hypericin, porphyrin, or an analog and the energy donating chemical is preferably luciferin or an analog. WebHowever, native hypericin is hydrophobic and nearly insoluble in aqueous media which hinders its photobiological activity. Herein, we demonstrate the encapsulation of …
