Electrochemical Dna-Nano Biosensor for the Detection of Cervical Cancer-Causing HPV-16 Using Ultrasmall Fe3O4-Au Core-Shell Nanoparticles

Dopamine levels determined in synthetic urine using an electrochemical tyrosinase biosensor based on ZnO@Au core–shell

“…18 Thus, the properties of these nanomaterials are promising for constructing biosensors with high sensitivity. For example, Rasouli et al 23 obtained the linear range from 1 and 10 mmol L −1 and a limit of detection of 0.1 nmol L −1 for human papillomavirus type 16 (HPV-16) using a biosensor formed by Fe 3 O 4 @Au core-shell as DNA support. Similarly, Güler et al 24 immobilised glucose oxidase (GOx) on Au@Pd core-shell nanoparticles supported on carboxylated graphene oxide (cGO) to construct a glucose biosensor with a linear range from 0.2 to 4200 mmol L −1 and limit of detection of 10.4 mmol L −1 .…”
