  Design of Asymmetric Particles Containing a Charged Interior and a Neutral Surface Charge: Comparative Study on in Vivo Circulation of Polyelectrolyte Microgels

  摘要：

  Lowering the modulus of hydrogel particles could enable them to bypass in vivo physical barriers that would otherwise filter particles with similar size but higher a modulus. Incorporation of electrolyte moieties into the polymer network of hydrogel particles to increase the swelling ratio is a straightforward and quite efficient way to decrease the modulus. In addition, charged groups in hydrogel particles can also help secure cargoes. However, the distribution of charged groups on the surface of a particle can accelerate the clearance of particles. Herein, we developed a method to synthesize highly swollen microgels of precise size with near-neutral surface charge while retaining interior charged groups. A strategy was employed to enable a particle to be highly cross-linked with very small mesh size, and subsequently PEGylated to quench the exterior amines only without affecting the internal amines. Acidic degradation of the cross-linker allows for swelling of the particles to microgels with a desired size and deformability. The microgels fabricated demonstrated extended circulation in vivo compared to their counterparts with a charged surface, and could potentially be utilized in in vivo applications including as oxygen carriers or nucleic acid scavengers.

  Disclosed is a gas barrier film which uses a polymerizable inorganic compound and has both high barrier property and high surface smoothness. Also disclosed are a resin base for organic electroluminescent devices using such a gas barrier film, an organic electroluminescent device and a method for producing a gas barrier film. The gas barrier film is characterized by comprising at least one ceramic film and a coating layer, which is formed through application of a coating liquid containing a polymerizable inorganic compound, on a resin film in this order. The gas barrier film is further characterized in that the ceramic film has a residual stress of not less than 0.01 MPa but not more than 20 MPa.
