“…High-resolution EDX mapping reveals the uniform distribution of Pt (Figure 5b), W (Figure 5e), and Pd (Figure 5h) in the NPs. The changes of Q bands of the TCPP ligands in the UV/Vis spectra (Figure S6) agree well with previous reports, [32][33][34] confirming the chelating of the non-Zr metals with porphyrin. Calculation based on the non-Zr metal contents determined by ICP-OES and the particle sizes reveals that the metal loading were 1.3 × 10 3 Pt atoms per NP, 1.1 × 10 3 W atoms per NP and 8.5 × 10 2 Pd atoms per NP, respectively (Table S2).…”

Single-cell multiplexing is key to exploration of the heterogeneous cell populations in biological systems. Although the state-of-the-art mass cytometry (CyTOF) possesses high resolution and multiple dimensions, the lack of suitable marker materials prohibits fully exploiting the available CyTOF detection channels.Here we report a new design strategy for CyTOF markers using functionalized mesoporous porphyrinic frameworks (MPFs) as scaffolds for chelating metals that have been unachievable by conventional approaches. We developed surface modification for stably dispersing the MPF nanoparticles (< 40 nm) during the metalation and antibody conjugation processes. Our markers exhibit higher sensitivity and comparable specificity compared with a polymer-based commercial benchmark. Compatibility with commercial markers during co-staining was also confirmed. Furthermore, our markers show promising performance for immunophenotyping and potential implementation in CyTOF systems.

“…In order to overcome this disadvantage, phosphorescent molecules are usually entrapped in special matrices to inhibit their non‐radiative transitions, typically like molecular collision of the phosphors caused by thermal motion . Towards that end, a number of materials have been used as matrices loading with phosphorescent molecules, such as solid matrices, ionic liquid, polymers, micelles, and sodium deoxycholate…”

Meso‐tetra (carbonyl phenyl) porphyrin palladium (denoted as Pd‐TCPP), a typical organometallic compound, was used as phosphor and entrapped in micelle‐hybridized supramolecular hydrogels. As a novel matrix material of phosphors, the hybrid system was comprised of two ordered structures: a supramolecular 3D network structure formed by the self‐assembly of the gelator and the micelles formed from a Gemini surfactant. The dual‐ordered structure of the system was verified by SEM, TEM and fluorescent optical microscopy. By contrast with corresponding mono‐ordered structure, the room temperature phosphorescence (RTP) of Pd‐TCPP was greatly enhanced by the dual‐ordered structure of the system. The enhancement mechanism of RTP was studied by hydrophobicity of the system, RTP quenching and disassembly of supramolecular aggregates. Enhanced RTP could be attributed to the efficient inhibition of the non‐radiative transition of Pd‐TCPP by dual‐ordered structures. Significantly, the RTP intensity of Pd‐TCPP can be adjusted by changing the concentration of Gemini surfactants. Furthermore, deoxygenation was not required in this hybrid system in comparison with corresponding mono‐component systems.
