A quartz crystal microbalance biosensor based on polyethylenimine-modified gold electrode to detect hepatitis B biomarker
Summary
A QCM immunosensor for the hepatitis B surface antigen, built by attaching antibodies to a gold electrode modified with polyethylenimine and optimised by response surface methodology. It covers 1 to 1000 ng/mL with a detection limit of about 3 ng/mL, works in human serum with results close to ELISA and around 91% recovery, and can be fully regenerated.
Summary written by the openQCM team. The original abstract is on the publisher’s page.
