    <p>Inexpensive glass capillary microfluidic devices with co-flow geometry were prepared to generate highly monodispersed microbubbles with a controlled size of less than 10 µm for medical applications. In the analysis, the dimensions of the injection and collection capillaries were decreased, and the gas pressure and liquid phase flow rate were increased to their respective limits. The diameter of the monodisperse microbubbles (having a coefficient of variation of less than 1.5%) could be controlled within the range of 2.4–9.2 µm, while maintaining a generation rate on the order of 10<sup>5</sup> bubbles/s by adjusting the inner tip diameter of the injection capillary and the liquid phase flow rate. The inner diameter of the collection capillary was 30 µm, and the gas pressure was 0.50 MPa.</p>

  • Visualization of Strain Using Elastomer-Immobilized Tunable Colloidal Photonic Crystal Films

    <p>Tunable colloidal photonic crystal films consisting of loosely packed colloidal crystals immobilized in elastomers were prepared. The prepared soft film was adhered to an aluminum specimen and the tensile testing was performed. Before applying the tensile force, the film exhibited red color due to Bragg reflection from (111) lattice planes of the face-centered cubic structure, which are parallel to the film surface. With increasing strain on the specimen, the Bragg wavelength of the colloidal crystals was blue-shifted, mainly owing to reduction of the lattice spacing. Consequently, the color of the film changed to orange, yellow, and green in accordance with increasing strain. The prepared films can be used as simple sensors that detect the strain on the materials to which they are adhered based on color change.</p>
