Bimetallic MnCo oxide nanohybrids prepared from Prussian blue analogue for application as impedimetric aptasensor carrier to detect myoglobin

•MnOxCoOy hybrids with varying morphologies were derived from the bimetallic PBA.•A simple anchoring platform was developed for myoglobin determination.•The developed aptsensor exhibits good sensitivity, selectivity, and stability.•The aptasensor also possesses reproducibility and acceptability in human serum.•The aptamer anchoring platform can be universal for other aptamers.
