Poly(ethyleneimine) solution

New methods for materials fabrication at the micro- and nanoscale will drive scientific and technological advances in areas of materials science, chemistry, physics, and biology. The broad diversity of potentially relevant materials, length scales, and architectures underscores the need for flexible patterning approaches. One important example is the fabrication of 3D periodic structures composed of colloidal, polymeric, or semiconductor5 materials.

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.

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

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