An electrochemical aptasensor based on catalytic hairpin self-assembly and co-amplification of AuPd/Fe-MOF and Au/Cu2O for ultrasensitive detection of Cd2

Cadmium (Cd), a typical heavy metal not essential for the human body, can cause harm to the liver and kidneys upon exposure. Hence, rapid cadmium detection in the environment is of utmost importance. This research presents an effective approach for detecting divalent cadmium ions (Cd 2+ ) using a se...
