Magnetically separable h-Fe3O4@Au/polydopamine nanosphere with a hollow interior: A versatile candidate for nanocatalysis and metal ion adsorption

Polydopamine, harness of the antibacterial potentials-A review

“…However, a condition such as the employment of nanocarriers or encapsulation with porous templates presents the nanoparticles with many advantages improving and even presenting them with improved effectiveness, reduced toxicity, and an electrostatic attraction to other surfaces and membranes. Intriguingly, the PDA can present a mesoporous effect and a firm adherence on varying surfaces through strong intermolecular interactions [ [108] , [109] , [110] ].…”

In Site Generation of Well‐Dispersed Ag3PO4 NPs on Protein‐Inorganic Hybrid Nanoflowers with Enhanced Catalytic Performance

“…Figure 4B demonstrates that hybrid nanoflowers modified with Ag 3 PO 4 possess enhanced catalytic performance. In the absence of a catalyst, it is difficult for NaBH to reduce 4‐NP [26] . While, after adding a certain amount of the absorbance band at 400 nm successively decrease with increasing reaction time.…”

“…In the absence of a catalyst, it is difficult for NaBH to reduce 4-NP. [26] While, after adding a certain amount of the ChemistrySelect absorbance band at 400 nm successively decrease with increasing reaction time. Obviously, it is worth noting that the catalytic activity of Cu 3 (PO 4 ) 2 @BSA@Ag 3 PO 4 is higher than Cu 3 (PO 4 ) 2 @BSA at the same amount of the composite, which is in accordance with their morphology properties presented above.…”

Recent Advances in Synthesis, Medical Applications and Challenges for Gold-Coated Iron Oxide: Comprehensive Study

“…A similar AMF condition was demonstrated with the heating efficiency of Au NPs combined with non-conductive and diamagnetic SiO 2 NPs, which demonstrates that sustained heat for HNPs may be due to the supplementary heating of the Au NPs in a radiation frequency solenoid belt (RF). A novel hollow nanosphere Fe 3 O 4 @Au/polydopamine (Au/PDA) capable of absorbing potentially toxic ions plus catalyzing the decrease in 4-nitrophenol has been published [ 39 ]. The hybrid shell has well encapsulated the hollow nanosphere Fe 3 O 4 (Au/PDA) to create the dual-functioning magnetics hollow nanocomposites utilizing an easy redox-oxidizing polymerization technique ( Figure 2 ).…”
