Peroxidase-mimetic, electrochemically active, Co3O4-decorated pectic acid-based polyacrylate derivatives for rapid and sensitive hydrogen peroxide detection in apple juice samples

In this work, a nanocomposite of a pectic acid (PcA)-based copolymer composed of acrylamide (Am) and acrylic acid (AcA) embedding cobalt oxide nanoparticles (Co3O4 NPs), PcA-g-poly(Am-co-AcA)/Co3O4, was fabricated as an enzyme-free electrochemical sensing platform for the sensitive detection of hydrogen peroxide (H2O2)...

Electroactive MnO2 nanorods-integrated grafted pectic acid nanocomposite for enzyme-free hydrogen peroxide determination in milk and salami samples.

Grafting pectic acid (PecA) is fueled by free radical copolymerization of acrylic acid (AcA) and acrylamide (AAm), [PecA-g-poly (AAm-co-AcA)], embedded with manganese dioxide-nanorods (MnO2-NRs) produced an inventive nanocomposite, [PecA-g-poly (AAm-co-AcA)/MnO2-NRs]. Fourier-transform infrared (FT-IR) spectroscopic an...
