thermogelation of a triblock copolymer Pluronic F127 (poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide)) in an aqueous solvent in the presence of gold nanoparticles, using pulsed-field gradient diffusion, NMR temperature experiments, relaxation measurements, and 2D heteronuclear NMR ...
Redox-sensitive Pluronic F127-tocopherol micelles Results and discussion Synthesis and characterization of F127-SS-TOC polymer F127-SS-TOC polymer was synthesized and confirmed by 1H NMR spectra. As shown in Figure 3, typical signals for F127 polymer were observed, including peaks a (δ ~1.02 ...

. We have revealed their ability to adhere to the triblock copolymer pluronic-F127 (PF127) and form a platelet microvesicular nanocloud which has the potential to enhance the transvascular migration of hematopoietic stem cells across the sinusoidal endothelium to the bone marrow. Besides, the pMVs...
The FTIR and 1H NMR spectra confirmed that Conclusions Dual-crosslinked hydrogels for cell encapsulation were successfully prepared by altering the compositions of TIC (Plu-F127) and NIC (network of Dex-VS and PEG-SH) components and the molecular weight of Dex-VS, which directly affected not ...
Three techniques, Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), and nuclear magnetic resonance spectroscopy (NMR) in both one-dimension and two-dimension (Nuclear overhauser effect spectroscopy; NOESY) were used to gain an insight into the interactions between ...
利用1HNMR和R对叶酸封端的F127(F127.fola te)的结构进行表征。用透析法制备胶束溶液,采用表面张力法测量临界胶束浓 度CMC。胶束的粒径和形态采用动态光散射法(DLS)和透射电子显微镜(T EM)测量,结果表明胶束的粒子大小受嵌段共聚物浓度和温度影响。5氟尿嘧啶 作为模型药物体外释放结果表明F127.folate胶束具有明显的缓释...
The Mn and PEG/PCL ratio of PECE triblock copolymer calculated from 1H-NMR spectra was 3408 and 960/2448 respectively. Macromolecular weight and macromolecular weight distribution (polydispersity, PDI, Mw/Mn) of PECE triblock copolymer determined by GPC were 4391 and 1.30 respectively [24]. ...
