Construction of magnetic self-assembled electrochemical biosensor with TiO2@Co/C@Au nanocomposite for sensitive detection of PIK3CA gene.
PIK3CA gene mutations are key drivers in various malignant tumors, and their highly sensitive detection is crucial for tumor diagnosis. This study aims to develop a label-free electrochemical biosensor based on a TiO2@Co/C@Au nanocomposite for highly sensitive detection of the PIK3CA gene. By optimizing the synthesis c...
