Polyplex particles formed with plasmid DNA (pDNA) and Pluronic P85-block-poly{N-[N-(2-aminoethyl)-2-aminoethyl]aspartamide} (P85-b-P[Asp(DET)]) demonstrated highly effective transfection ability compared to PEG-based block cationomer, PEG-b-P[Asp(DET)]. Ternary polyplexes comprising PEG-b-P[Asp(DET)], poly(ethylene oxide)-b-poly(propylene oxide)-b-poly(ethylene oxide)-b-P[Asp(DET)] (P(EPE)-b-P[Asp(DET)]) used as an analog of P85-b-P[Asp(DET)], and pDNA were

A novel method for the determination of nickel was established by ultrasonic-assisted cloud point extraction (UA-CPE) prior to flame atomic absorption spectrometry (FAAS) analysis. The nickel reacted with N,N'-bis(salicylidene)-1,2-ethanediamine (BSE) to form hydrophobic chelates, which were extracted into the micelles
