Herein, we demonstrate the use of modified gold-coated magnetic nanoparticles as 'dispersible electrodes' which act as selective capture vehicles for electrochemical detection of prostate-specific antigen (PSA). A key advantage of this system is the ability to quantify non-electrochemical active analytes such as proteins with unprecedented detection limits and fast response times.
