Journal ArticleDOI
Electrochemical sensing of hydrogen peroxide using metal nanoparticles: a review
TL;DR: In this article, the state of electrochemical sensing of H2O2 based on the use of metal nanoparticles is reviewed, which is divided into sections on sensors based on heme proteins and on nonenzymatic sensors.
Journal ArticleDOI
Ultrasensitive electrochemical immunosensor for clinical immunoassay using thionine-doped magnetic gold nanospheres as labels and horseradish peroxidase as enhancer.
TL;DR: The developed immunoassay method showed good precision, high sensitivity, acceptable stability and reproducibility, and could be used for the detection of real samples with consistent results in comparison with those obtained by the enzyme-linked immunosorbent assay (ELISA) method.
Journal ArticleDOI
In situ hybridization chain reaction amplification for universal and highly sensitive electrochemiluminescent detection of DNA.
TL;DR: The proposed strategy combines the amplification power of the DNA HCR and the inherent high sensitivity of the ECL technique and enables low femtomolar detection of sequence specific DNA.
Journal ArticleDOI
Magnetic core-shell Fe3O4@Ag nanoparticles coated carbon paste interface for studies of carcinoembryonic antigen in clinical immunoassay.
TL;DR: A novel approach toward development of advanced immunosensors based on chemically functionalized core-shell Fe3O4@Ag magnetic nanoparticles, and the preparation, characterization, and measurement of relevant properties of the immunosensor useful for the detection of carcinoembryonic antigen (CEA) in clinical immunoassay.
Journal ArticleDOI
Amperometric third-generation hydrogen peroxide biosensor based on the immobilization of hemoglobin on multiwall carbon nanotubes and gold colloidal nanoparticles
TL;DR: A convenient and effective strategy for preparation nanohybrid film of multi-wall carbon nanotubes (MWNT) and gold colloidal nanoparticles (GNPs) by using proteins as linker by using hemoglobin (Hb) as model protein to fabricate third-generation H2O2 biosensor based on MWNT and GNPs.
