Seoul, – A group of South Korean researchers have developed a new photodynamic therapy (PDT) method to target tumor cells, the South Korean science ministry said, opening up new treatment opportunities for patients.

PDT, a method of exposing a drug called a photosensitizer to a specific wavelength of light, has been widely studied as a promising non-invasive therapeutic strategy for the treatment of cancer. However, the poor solubility of the photosensitizer and inefficient cell-penetration rate have often resulted in side effects such as serious damage to skin tissue.

The team, led by Min Dal-hee of Seoul National University, developed the novel photodynamic therapeutic system of using a two-dimensional “nanosheet” as a new carrier of the photosensitizer, the Ministry of Science, ICT and Future Planning said.

“This research was focused on developing a two-dimensional nanosheet that only targets cancer tumors by minimizing the damage to other cells,” Min said. “The treatment is forecast to be used for lung and cervical cancers that are difficult to treat”.

The research was funded by the science ministry and the findings were published in the latest edition of “2D Materials”. (QNA)
