Noble Metal Nanozymes-Product List

Pt nanozymes can catalyze H₂O₂ in situ in tumors to generate O₂ to improve the hypoxic environment, improve the efficiency of photochlor (HPPH)-mediated photodynamic therapy (PDT), and generate more reactive oxygen species to kill tumor cells more effectively.

PtRu nanozymes exhibit both antioxidant and pro-oxidative functions. On the one hand, they can catalyze the oxidation of organic substrate molecules and metal ions, and on the other hand, they can effectively scavenge free radicals and living molecules. The enzyme-like catalytic activity of PtRu nanoparticles is highly dependent on the Pt/Ru alloy ratio, and as the components change, their antioxidant capacity and pro-oxidative capacity show the same changing trend. In addition, based on their excellent catalytic activity, PtRu nanozymes can be used to protect the natural active product monascus pigment from oxidative decomposition.

PtCu nanozymes have multiple simulated enzyme activities such as catalase-like, peroxidase-like and superoxide dismutase-like, as well as the ability to scavenge free radicals, which can inhibit the generation of reactive oxygen species. PtCu nanozymes also have good biocompatibility and strong antioxidant properties. They show significant efficacy in preventing the diffusion of α-synuclein in sporadic Parkinson's disease, providing a new strategy for the treatment of Parkinson's disease.

Taking advantage of the good charge transfer and synergistic effects between gold, platinum, and cobalt elements, AuPtCo nanozymes exhibit strong catalytic activity. AuPtCo nanozymes can catalyze the Chemiluminescence (CL) emission in a flash type after reacting with the substrate N-(4-Aminobutyl)-N-ethylisoluminol (ABEI) and the oxidant H₂O₂.

PtPdCu nanozymes exhibit excellent enzyme-like catalytic activities including peroxidase, hephaestin and catalase. They also possess 1,1-diphenyl-2-trinitrophenylhydrazine (DPPH) free radical scavenging ability. Based on the inhibitory effect of antioxidant molecules on their peroxidase-like activity, PtPdCu nanozymes can be used for antioxidant capacity analysis. The excellent hephaestin characteristics of PtPdCu nanozymes can be used for the detection of Fe²⁺. This method has high selectivity, high sensitivity and good accuracy, and can be used for the determination of Fe content in iron supplement oral solutions. In addition, the excellent catalase activity and free radical scavenging ability of PtPdCu nanozymes are also expected to play a role in biological protection.

The catalytic activity of PdPtAu nanozymes mainly comes from the metal atoms and crystal faces on their surface. By doping different proportions of Pt and Au, the surface electronic structure and chemical properties of Pd can be changed, thereby affecting their interaction with substrates and oxidants. PdPtAu nanozymes can play a role in the fields of electrocatalysis, biosensing and tumor treatment.
