Opis ogólny

Polyethyleneimine is a hydrophilic polymerwidely used as a non-viral synthetic vector for invivo delivery of therapeutic nucleic acids. Owing to its excellentphysicochemical properties, it is applied in many fields like the separationand purification of proteins, carbon dioxide absorption, drug carriers,effluent treatment, and biological labels.

Zastosowanie

Branched PEI can be used as a precursor to synthesize conjugated polyplexes for efficient gene transfection. Conjugation of PEI with Jeffamine polyether and guanidinylation of the amino groups of PEI reduce the cytotoxicity of the polyplexes and protect them from aggregation in the presence of serum proteins.

Bamboo charcoal impregnated with PEI can be used as a CO2 adsorbent. Numerous amino groups present in PEI can react with CO2 due to acid-alkali interaction and enhance the adsorption capacity of bamboo charcoal.

It can also be used to prepare cross-linked water-soluble polymers with high coordination capabilities towards organic drug molecules.

Cechy i korzyści

  • Branched PEI has better complexation and buffering capacity.
  • High ion exchange capacity and affinity toward proteins.
  • SignificantDNA transfer efficiency.

Developing a controlled method for obtaining hybrid enzymatic-based interfaces for sensing application require the use of a multiuse, reusable sensor. By controlling the interface characteristics in terms of the surface chemistry, thickness, and roughness, a tailored response toward various toxic

Insurmountable detection challenges will impede the development of many of the next-generation of lab-on-a-chip devices (e.g., point-of-care and real-time health monitors). Here we present the first membrane-based, microfluidic sample preconcentration method that is continuous, quantifiable, simple, and capable of working
