 This research paper discusses the use of a new type of sensor material, La2SN207, slash FHNT nanocomposite, which has been developed to detect low levels of three nitro-L tyrosine in urine samples. This compound is known to be associated with cancer, so its presence could indicate the presence of cancer cells. The sensor material was successfully synthesized using a hydrothermal process, and it was found to have excellent performance when used in an electrochemical detector. The sensor showed a limit of detection of 0.012 muM, making it highly sensitive and capable of detecting even small amounts of three nitro-L tyrosine. This research demonstrates the potential of nanomaterial-based sensors in early disease detection, providing valuable insight into cellular oxidative processes.
