PEI nanoparticles

A highly dispersible and magnetically recoverable Cu-PEI@Fe 3 O4 MNPs catalyst was prepared and successfully applied in one-pot three-component coupling of terminal alkynes, sodium azide, and alkyl bromides/chlorides in water to give 1,4-disubstituted 1,2,3-triazoles with good to excellent yields. The catalyst was fully characterized with FT-IR, TGA, TEM, SEM, VSM, EDX, cyclic voltammetry, and ICP-AES spectroscopic techniques.

The Special AT-rich Sequence Binding Protein 1 (SATB1) regulates the expression of many genes by acting as a global chromatin organizer. While in many tumor entities SATB1 overexpression has been observed and connected to pro-tumorigenic processes, somewhat contradictory evidence exists in brain tumors with regard to SATB1 overexpression in glioblastoma and its association with poorer prognosis and tumor progression.

Nonviral gene delivery systems are considered to be a safe alternative to the viral system used in gene therapy. Although polyethylenimine (PEI) is among the most promising gene-carrier candidates for efficient nonviral gene delivery, safety concerns regarding its toxicity remain challenging.

Li et al. Nanoscale Research Letters 2011, 6:356 http://www.nanoscalereslett.com/content/6/1/356 NANO EXPRESS Open Access Study on the visible-light-induced photokilling effect of nitrogen-doped TiO2 nanoparticles on cancer cells Zheng Li1, Lan Mi1*, Pei-Nan Wang1 and Ji-Yao Chen2 Abstract Nitrogen-doped TiO2 (N-TiO2) nanoparticles were prepared by calcining the anatase TiO2 nanoparticles under ammonia atmosphere. The N-TiO2 showed higher absorbance in the visible region than the pure TiO2.
