Molecular imprinted nanoelectrodes for ultra sensitive detection of ovarian cancer marker

► Imprinted polymer on gold nanoelectrode to detect ovarian cancer antigen-125 was developed. ► This sensor showed good increments at the concentration range of 0.5-400 U mL−1. ► MIPGNEE offers an alternative approach for the trace detection of CA 125 biomarkers in clinical analysis.
