Gentle Light Therapy Kills Cancer Cells
25 Nov
Summary
- New treatment uses LED light and tin oxide nanoflakes to target cancer.
- It heats and destroys cancer cells while sparing healthy tissue.
- The technology promises a safer, less invasive cancer treatment option.
A groundbreaking advancement in cancer treatment has emerged from US research, combining accessible LED light with microscopic tin oxide nanoflakes. This photothermal therapy precisely targets and heats malignant cells, leading to their destruction while largely sparing healthy tissue. This method offers a significant departure from conventional treatments, which often cause substantial side effects by damaging healthy cells alongside cancerous ones.
The innovation centers on SnOx nanoflakes, engineered to absorb near-infrared light and generate localized heat. This process effectively disrupts cancer cell membranes and proteins. Unlike laser-based systems, the use of gentler LEDs makes the treatment safer and potentially suitable for at-home use. Laboratory tests demonstrated up to 92% destruction of skin cancer cells, with minimal impact on healthy human cells.
This development holds potential for various applications, including post-surgical care to eliminate residual cancer cells and as a component in combination therapies to enhance treatment efficacy. The technology's affordability and ease of use could also expand access to advanced cancer care in underserved regions, paving the way for more precise, cost-effective, and humane cancer treatment.
