Achieving enhanced peroxidase-like activity in multimetallic nanorattles

Abstract

Gold nanoparticles (Au NPs) have been extensively employed as artificial enzymes, but their performance is still limited. We address this challenge by focusing on multimetallic nanorattles comprised of an Au...

Mesoporous silica-supported platinum nanocatalysts for colorimetric detection of glucose, cholesterol, and C-reactive protein

“…Many kinds of noble metal-based nanomaterials have so far been developed in this regard. 41,42 For example, Pd nanocubes with a shallow Ir coating could show a detection limit more than 100-fold lower than that by horseradish peroxidase (HRP) for prostate surface antigen as the target analyte in an immunoassay. 43 Porous Pt nanocrystals were able to rapidly detect p24 capsid protein of a human immunodeficiency virus in the femtomolar range in a lateral flow assay.…”
