Analysis of Surface Interaction between TiO2 Fine Particles with Different Surface Modification in Isoparaffin by Using Colloid Probe AFM

Kamiya H., Suzuki M., Kikuchi M., Iijima M., Tsukada M., Tokyo University of Agriculture and Technology, JP

To control the dispersion stability of nanometer scaled fine inorganic particles in organic solvent, various kinds of surface modification on particles have been carried out. This paper focused on the surface modification on titanium oxide [...]

Interaction between Artificial Mucin Layer and Stimuli-Responsive Nanogel Particles for the Oral Peptide Delivery Observed in Simulated Intestinal Solutions by Using Colloid Probe AFM Method

Kamiya H., Yoshimura M., Tsukada M., Ichikawa H., Fukumori Y., Tokyo University of Agriculture and Technology, JP

In order to characterize and control the adhesive behaviors of nanometer scaled stimuli-responsible gel particles designed for oral peptide delivery, their interaction with artificial mucin layer in the small intestinal solutions was determined by the [...]

Functional Stimuli-Responsive Nanogel-particles for Oral Peptide Delivery: Preparation, Drug-Release Behaviors and in Vitro Cellular Interaction

Ichikawa H., Fukumori Y., Kamiya H., Kobe Gakuin University, JP

The present study involves preparation and evaluation of novel core-shell nanoparticles (CSNPs) consisting of thermo-responsive poly(N-isopropylacrylamide) (p(NIPAAm)) hydrogel core with pH-responsive poly(methacrylic acid-grafted-poly(ethylene glycol)) (p(MAA-g-EG)) shell layer as a carrier for oral peptide delivery. The [...]
