Scientists have made an exciting breakthrough in cancer treatment that uses LED lights and tiny flakes of tin to target cancer cells. This new therapy aims to be less painful than traditional methods like chemotherapy, which often come with severe side effects.
The research comes from a collaboration between The University of Texas at Austin and the University of Porto in Portugal. This project is part of the UT Austin Portugal Program, which seeks to create more accessible and affordable cancer treatments. Traditional therapies typically involve costly materials and setups that can harm healthy tissue. However, this new approach uses LEDs and special tin-based nanoflakes, making it safer and potentially cheaper.
Professor Jean Anne Incorvia from UT Austin explains, “We wanted to develop a method that is effective yet safe and easy to access.” In their recent study published in ACS Nano, the researchers found that this LED treatment could kill up to 92% of skin cancer cells and 50% of colorectal cancer cells in just 30 minutes, without damaging healthy skin cells. These results show the therapy’s accuracy and safety.
Globally, cancer is the second-leading cause of death. Many current treatments have harsh side effects, prompting scientists to search for new, more focused methods. Near-infrared photothermal therapy, which uses light to heat and destroy cancer, is one of the promising alternatives. The team in Texas and Portugal is building on this idea.
Looking ahead, researchers are testing different materials to improve the treatment and plan to create medical devices that can deliver it to patients more effectively. “We want to make this available to everyone, especially in areas with limited access to complex equipment,” said Artur Pinto from the University of Porto. They envision a future where treatments could happen at home, potentially reducing the risk of recurrence for skin cancer patients.
The collaboration between Incorvia and Pinto began in 2021, allowing them to share ideas and advance cancer therapies. Recently, their efforts received additional funding to develop an implant specifically for breast cancer patients using the same innovative technology.
As they continue this important work, the hope is to create personalized, affordable, and pain-free treatments in the near future. The UT Austin Portugal Program has been a vital link in this effort, promoting science and technology partnerships for over 17 years.
This research signifies a promising shift in cancer treatment, utilizing modern technology to change how patients experience care. With advancements like these, the landscape of cancer therapy may become much brighter.
