Accelerating peroxidase mimicking nanozymes using DNA

Liu, Biwu; Liu, Juewen (Royal Society of Chemistry, 2015-09-07)

DNA-capped iron oxide nanoparticles are nearly 10-fold more active as a peroxidase mimic for TMB oxidation than naked nanoparticles. To understand the mechanism, the effect of DNA length and sequence is systematically ...
Attaching DNA to Nanoceria: Regulating Oxidase Activity and Fluorescence Quenching

Pautler, Rachel; Kelly, Erin Y.; Huang, Po-Jung Jimmy; Cao, Jing; Liu, Biwu; Liu, Juewen (American Chemical Society, 2013-08-14)

Cerium oxide nanoparticles (nanoceria) have recently emerged as a nanozyme with oxidase activity. In this work, we present a few important interfacial properties of nanoceria. First, the surface charge of nanoceria can be ...
Gold nanoparticles as dehydrogenase mimicking nanozymes for estradiol degradation

Zhang, Zijie; Bragg, Leslie M.; Servos, Mark R.; Liu, Juewen (Elsevier, 2019-09)

Nanozyme catalysis has been mainly focused on a few chromogenic and fluorogenic substrates, while environmentally and biologically important compounds need to be tested to advance the field. In this work, we studied oxidation ...
