  2. The inhibition efficiency of zinc anode corrosion reaches up to 52.2% in the electrolyte with 50 ppm PEI, and the surface roughness of the corroded zinc anode is significantly reduced. In addition, a zinc-air full cell with PEI additive exhibits good cycling stability at current densities of 5 mA cm −1 and 10 mA cm −1 , which can be attributed to the mitigation of electrode deterioration.

Polyethylenimine (PEI) has been used to transfect a wide variety of cell-types both in cell culture and in vivo. PEI is available in both branched and linear forms. Initially, very long, branched polymers (800 kDa mean molecular weight) of PEI were used to transfect mammalian cells (Boussif et al., 1995) Hollow silica particles prepared by a self-templating method using polyethylenimine. obtained hollow silica particles by dissolution of silica particles modified with a cationic polymer of PEI in water at 50 °C. Such a mild condition is suitable for the synthesis of hollow particles containing heat-sensitive materials such as metal nanoparticles. In the previous reports , , ], however. It was then dried at 50°C for 16 h in a vacuum-drying chamber. Following this step, the magnetite and polyethylenimine were left to mix (mass ratio 1:2) at room temperature for 24 h at pH 9.0. This procedure was performed under ultrasonic waves, so that the magnetic nanoparticles could homogenously disperse in the solution. The PEI-coated magnetic nanoparticles were thoroughly washed. This review discusses the possible roles of polyethylenimine (PEI) in the design of improved immobilized biocatalysts from diverse perspectives. This includes their use to activate supports and immobilize enzymes via ion exchange, as well as to improve immobilized enzymes by coating with PEI. PEI is a polyme Recent Review Article

Cationic hyperbranched polyethylenimine (hPEI) was covalently linked onto the backbone of cellulose molecules via forming Schiff base structure between the amino groups of hPEI and the aldehyde groups on the chemically oxidized cellulose surface. The functionalized hPEI-CE possessed available active sites, and its adsorption behavior to anionic dye congo red (CR) and cationic basic yellow 28. Here we report a method for one-pot synthesis of polyethylenimine/NaYF 4 nanoparticles doped with lanthanide ions, which are water soluble and biocompatible. The amino groups of polyethylenimine existing on the nanoparticles can be used for attachment of biomolecules. The nanoparticles showed a spherical shape with an average size of about 50 nm.

All polymers result in 40% to 50% PD-L1 protein knockdown. Importantly, SKOV-3-Luc cells treated with either PEI-FA or PEI- polyethylene glycol (PEG)-FA/PD-L1 siRNA complexes are up to twofold more sensitive to T cell killing compared to scrambled siRNA treated controls. These findings are the first to demonstrate that PD-L1 knockdown in EOC cells, via siRNA/FA-targeted delivery, are able to.
