Description
Prostate cancer is a leading killer of men, and early detection saves lives. Mohammad Safarpoor, Arash Asfaram, Mehrorang Ghaedi, and Rassoul Dinarvand build an electrochemical sensor for the PSA marker. The design loads MXene quantum dots with polyaniline and gold particles. These tags speed electron transfer and amplify the signal. A sandwich immunoassay gives the test its selectivity.
The sensor read PSA across a wide range, down to a detection limit of 0.61 femtograms per milliliter. Human serum tests supported its clinical promise. Specificity, repeatability, and stability all held up. The authors place MXene dots among the serious candidates for next-generation cancer sensors.
