There is provided an electroactive nanoparticle, which may be used as a label in electrochemical detection assays. The nanoparticle comprises a transition metal oxide and a capping agent, the capping agent comprising a ligand group and a functional group. The capping agent is coordinated to a transition metal centre in the transition metal oxide via the ligand group. Also provided are methods relating to preparation of the nanoparticle and detection of an analyte molecule in a sample using electrochemical methods.
