2D ultrathin nanosheets of Co–Al layered double hydroxides prepared in L-asparagine solution: enhanced peroxidase-like activity and colorimetric detection of glucose
TL;DR: This simple method did not need reflux at high temperature, overcame the drawback of using organic solvents, and even resulted in a stably stored colloidal suspension of 2D nanosheets, and the peroxidase-like activity of the exfoliated Co-Al LDH was enhanced compared with unexfoliated LDH.

Peroxidase-like activity of manganese selenide nanoparticles and its analytical application for visual detection of hydrogen peroxide and glucose
TL;DR: In this paper, a label-free colorimetric detection system for H2O2 and glucose was developed using a facile hydrothermal process in an alkaline glycerol/water solution system and used as peroxidase mimetics for detecting hydrogen peroxide and glucose.

Electrochemical immunosensor with graphene quantum dots and apoferritin-encapsulated Cu nanoparticles double-assisted signal amplification for detection of avian leukosis virus subgroup J.
TL;DR: A novel sandwich electrochemical immunoassay was developed for ultrasensitive detection of avian leukosis virus subgroup J (ALVs-J) using graphene quantum dots (GQDs) and apoferritin-encapsulated Cu (Cu-apferritin) nanoparticles for signal amplification.

A Cu2(OH)3Cl-CeO2 nanocomposite with peroxidase-like activity, and its application to the determination of hydrogen peroxide, glucose and cholesterol
TL;DR: In this article, a nanomaterial of the chemical composition Cu2(OH)3Cl-CeO2 and with a large surface area is shown to be a viable peroxidase mimetic, which was synthesized by co-precipitation of an aqueous solution containing Ce(III) chloride, Cu(II) chloride and hexamethylenetetramine by adding an ionic liquid.

Colorimetric sensing of dopamine based on the aggregation of gold nanoparticles induced by copper ions
TL;DR: In this paper, a colorimetric detection method for dopamine was proposed based on the interaction between Cu2+ ions with amino group and hydroxyl groups of the dopamine adsorbed on the surface of gold nanoparticles (GNPs).
