Highly luminescent and long-term anti-photobleaching Eu(TTA) 3 (TOP) 3 conjugated poly(St- co -DVB- co -NaSS- co -MAA) nanoparticles

Copolymerization of Eu(TTA)3Phen doped styrene and methyl methacrylate nanoparticles and use in quantitative detection of pepsinogen

“…[3][4][5][6] Europium complex doped latex nanoparticles are increasingly applied in clinical applications such as cellular and molecular imaging and immunodetection because of their relatively low cytotoxicity and good biocompatibility. 7 In this work, we found that europium complex doped copolymerization of PMMA and PS had stronger uorescence intensity than single polymerization. The effect on the uorescence intensity and the relationship between the styrene ratio and the methyl methacrylate ratio were investigated.…”

Highly Luminescent and Anti-Photobleaching Core-Shell Structure of Mesoporous Silica and Phosphatidylcholine Modified Superparamagnetic Iron Oxide Nanoparticles

“…The Eu(TTA) 3 (P(Oct) 3 ) 3 was prepared according to the previously reported method [ 29 ]. The chemical structure of Eu(TTA) 3 (P(Oct) 3 ) 3 was described in Scheme 1 (V) One micromole (0.366 g) Eu 3+ was dissolved in 50 mL of EtOH.…”

“…Based on the above theory, a study was reported in which carboxylic acid activated polystyrene-based copolymer nanoparticles were prepared and then synthesized fluorescent nanoparticles through coordination bonding of carboxylic acid and chelated Eu 3+ complex. As a result, those approaches proved that final composition has very high luminescent properties with an excellent anti-photobleaching [ 29 ]. However, although studies on fluorescent probes with core (magnetic)/shell(mSiO 2 ) structures have been conducted so far, no studies on Eu(TTA) 3 (P(Oct) 3 ) 3 chelated on mSiO 2 @SPION have been reported.…”

Real-Time Tracking of Highly Luminescent Mesoporous Silica Particles Modified with Europium β-Diketone Chelates in Living Cells

“…Eu(TTA) 3 (P(Oct) 3 ) 3 Complexes β-diketone europium complex Eu(TTA) 3 (P(Oct) 3 ) 3 is prepared with slight modification of previous study [32]. The synthetic route is illustrated in Figure 1.…”
