Scientists have introduced a new technology in a significant advancement in breast cancer treatment, which can rapidly assess the effectiveness of drugs in patients.
Experts from the Chinese Academy of Sciences, led by Professor Wang Hongzhi, have developed a biosensor called Meta Ring, which can quickly and accurately detect sensitivity to the drug paclitaxel used in breast cancer.
This research has been published in the journal Biosensors and Bioelectronics, stating that conventional tests are not only slow but also require larger samples, whereas Meta Ring works in less time and with a smaller amount of sample.
How does Meta Ring work?
This biosensor is based on the cavity ring effect, through which nanoparticles are arranged in a specific manner. This creates a highly sensitive structure that delivers accurate results even in different biological environments.
Furthermore, this technology uses surface enhanced Raman spectroscopy, which captures molecular fingerprints of cells to determine how cancer cells are responding to the drug.
With Meta Ring technology, the drug sensitivity test is completed in just 10 minutes, delivering results with over 92 percent accuracy. It requires a very small amount of biological sample and does not need labeling or cell culture.
This technology could help enable personalized treatment, allowing each patient to receive the most suitable medication according to their condition. According to experts, Meta Ring could play an important role in making cancer treatment more effective, faster, and patient specific in the future.
