Article Abstract
We investigated a series of Mn-Prussian blue (PB) nanoparticles NaMnFe[Fe(CN)]·HO of similar size, surface state and cubic morphology with various amounts of Mn synthesized through a one step self-assembly reaction. We demonstrated by a combined experimental-theoretical approach that during the synthesis, Mn substituted Fe up to a Mn/Na-Mn-Fe ratio of 32 at% in the PB structure, while for higher amounts, the Mn[Fe(CN)] analogue is obtained. For comparison, the post-synthetic insertion of Mn2+ in PB nanoparticles was also investigated and completed with Monte-Carlo simulations to probe the plausible adsorption sites. The photothermal conversion efficiency () of selected samples was determined and showed a clear dependence on the Mnamount with a maximum efficiency for a Mn/Na-Mn-Fe ratio of 10 at% associated with a dependence on the nanoparticle concentration. Evaluation of the photothermal properties of these nanoparticles performed on triple negative human breast adenocarcinoma (MDA-MB-231) cells by using continuous and pulsed laser irradiation confirm their excellent PTT efficiency permitting low dose use.

Here, we present three-dimensional-printed dual-channel flow-through miniaturized devices (3D) with dual electrochemical detection (ED) integrating two working electrodes each in an in-channel configuration (3D-ED). Prussian Blue (PB) shell-gold nanoparticles ((PB)AuNP) core-based electrochemistry was chosen for selective hydrogen peroxide determination. 3D-ED devices exhibited impress stability, identical intrachannel and interchannel electrochemical performances, and excellent interdevice precision with values under 9%, revealing the reliability of the design and fabrication of the devices.

Polymeric nanoparticles surface functionalised with fluorescent molecules hold significant potential for advancing diagnostics and therapeutic delivery. Despite their promise, challenges persist in achieving robust attachment of fluorescent molecules for real-time tracking. Weak physical adsorption, pH-dependent electrostatic capture, and hydrophobic interactions often fail to achieve stable attachment of fluorescent markers.

In this study, segmented hyperbranched copolymers with degradable and chain extendable cross-linker branch points were synthesized via green light-activated photoiniferter copolymerization of poly(ethylene glycol) methyl ether methacrylate (PEGMA) and a trithiocarbonate-derived dimethacrylate. A series of segmented hyperbranched copolymers with different degrees of branching were synthesized by changing the feed ratio of PEGMA to cross-linker to chain transfer agent. The segmented hyperbranched copolymers could be degraded into linear polymer chains by removing the trithocarbonate groups, which provides fundamental insights into the growth of primary chains during photoiniferter copolymerization.

Mass-fraction-optimized heterojunction composites featuring precisely engineered interfaces and mesoporous structures are crucial for improving light absorption, minimizing electron-hole recombination, and boosting overall catalytic efficiency. Herein, highly efficient mesoporous-NiFe2O4@g-C3N4 heterojunctions were developed by embedding p-type NiFe2O4 nanoparticles (NPs) within n-type porous ultrathin g-C3N4 (p-uCN) nanosheets. The optimized NiFe2O4@g-C3N4, loaded with 20wt% magnetic counterparts, exhibits exceptional photocatalytic methylene blue degradation, achieving the highest performance in both photocatalytic and photo-Fenton processes with rate constants of 0.
