One-pot synthesized Cu/Au/Pt trimetallic nanoparticles as a novel enzyme mimic for biosensing applications

Abstract

A class of novel Cu/Au/Pt TNPs with enhanced peroxidase-like activity was developed and used as enzyme mimics for biosensing.

Colorimetric sensing of glucose and GSH using core–shell Cu/Au nanoparticles with peroxidase mimicking activity

“…Compared with the previously reported colorimetric method for glucose detection, our proposed method has considerable linear range and sensitivity ( Table 1 ). And compared with other methods, Au@TiO 2 15 and R–Cu@Au/Pt NPs 50 have lower detection limits, but the synthesis method of Au@TiO 2 is complex and Pt is a relatively expensive metal material, which would increase the cost accordingly. This method has some advantages in glucose detection because of its simple operation and low cost.…”

Synthesis and potential applications of trimetallic nanostructures

“…Therefore, the NDs can be used as a diagnostic biomarker in ovarian cancer patients. 194 Wu et al 195 synthesized Cu/Au/Pt TMNs as a novel enzyme mimic for biosensing applications in H 2 O 2 catalytic reduction. The Cu/Au/Pt TMNs was synthesized in an earthworm-like structure with particle size of 20 nm.…”

Facile One-Pot Biogenic Synthesis of Cu-Co-Ni Trimetallic Nanoparticles for Enhanced Photocatalytic Dye Degradation

“…The trimetallic nanoparticles had recently gained appealing applications in the field of catalysis and are significantly manifested in various catalytic processes [2,3]. Trimetallic nanoparticles have a greater catalytic activity [4,5], increased antimicrobial action [6], diverse morphologies [7], highly selective detection and sensitivity [8][9][10], virtuous stability [11], and chemical transformation [12], when compared with monometallic nanoparticles. The biogenic or green synthetic approach of developing metal nanoparticles is a great challenge.…”
