일반 설명

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.

애플리케이션

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.

특징 및 장점

  • 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

Small interfering RNAs (siRNAs) are powerful tools commonly used for the specific inhibition of gene expression. However, vectorization is required to facilitate cell penetration and to prevent siRNA degradation by nucleases. We have shown that diamond nanocrystals coated with cationic

Gene therapy has become one of the most discussed techniques in biomedical research in recent years.

Professor Yoshiki Katayama (Kyushu University, Japan) discusses recent advances in drug delivery systems and strategies that exploit the EPR effect, with a special focus on stimuli-responsive systems based on novel materials.

We present an article that discusses two applications in particular; first, using these layers as polyelectrolyte membranes to control permeability.
