Summary of "Multi-functional lanthanide-CPs based on tricarboxylphenyl terpyridyl ligand as ratiometric luminescent thermometer and highly sensitive ion sensor with turn on/off effect."

A series of isostructural lanthanide coordination polymers (Ln-CPs) formulated as [Ln(tcptpy)(H2O)2·2H2O]n {Ln3+ = Sm3+ (1), Eu3+ (2), Gd3+ (3), Tb3+ (4), Dy3+ (5); H3tcptpy = 4-(2,4,6-tricarboxylphenyl)-4,2':6',4''-terpyridine} has been afforded and characterized systematically. Their structures were established by single-crystal X-ray diffraction. All the complexes feature two dimensional (2D) layers with (4,4)-connected topology. By virtue of the isostructural frameworks, a family of binary co-doped Ln-CPs [Tb1-xEuxtcptpy]n was achieved for ratiometric temperature sensors, among which Tb0.897Eu0.103tcptpy exhibits a good linear response to the temperature range from 305-340 K, with a maximum relative sensitivity (Sm) of 8.41% K-1 at 340 K. Moreover, Tb-CPs exhibit excellent applications as luminescent sensors for the detection of nitrobenzene and Fe3+ cations with high selectivity and sensitivity based on a luminescence quenching approach. The possible mechanisms of the fluorescence quenching effect were also investigated.

Medical and Biotech [MESH] Definitions

A multi- and interdisciplinary field concerned with improving health and achieving equity in health for all people. It transcends national boundaries, promotes cooperation and collaboration within and beyond health science fields, and combines population-based disease prevention with individually-based patient care.

Process of classifying cells of the immune system based on structural and functional differences. The process is commonly used to analyze and sort T-lymphocytes into subsets based on CD antigens by the technique of flow cytometry.

The use of technology-based interventions to improve functional capacities rather than to treat disease.

A transmembrane-protein belonging to the TNF family of intercellular signaling proteins. It is a widely expressed ligand that activates APOPTOSIS by binding to TNF-RELATED APOPTOSIS-INDUCING LIGAND RECEPTORS. The membrane-bound form of the protein can be cleaved by specific CYSTEINE ENDOPEPTIDASES to form a soluble ligand form.

A multi-functional catenin that participates in CELL ADHESION and nuclear signaling. Beta catenin binds CADHERINS and helps link their cytoplasmic tails to the ACTIN in the CYTOSKELETON via ALPHA CATENIN. It also serves as a transcriptional co-activator and downstream component of WNT PROTEIN-mediated SIGNAL TRANSDUCTION PATHWAYS.
