Mathematical modeling plays an important role in studying the glucose-responsive behavior of chemically-controlled closed-loop system for design and optimization. In this study, a glucose-responsive swelling model controlled by seven main equations was established and solved to investigate the glucose-responsive behavior of Con A-DexG hydrogel-based chemically-controlled closed-loop system. The swelling ratio Q and diffusion coefficient D are two variables in the model, and they can help design the molecular structure of the hydrogel (i.e., a mixture of Con A and DexG) with a potential to design a personalized insulin delivery system......

Bioengineering synthetic materials to replace some specific human functions is the inevitable direction of development in the field of materials in the near future. Synthetic materials containing living cells will have a broad application prospect in skin replacement. For example, the market scale of wound repair (avoiding donor site injury, promoting healing, and improving healing quality), such as in vitro validation of beauty products will be 10 billion US dollars. Up to now, in the research of skin substitute materials, many research teams around the world have released a lot of research results, but they still have not fully developed an artificial composite material that can replace human skin......

The pure zirconia has three different crystal structures: monoclinic, m-ZrO2 , tetragonal, t-ZrO2 , and cubic, c-ZrO2 [1]. The crystal structures are shown in (Figure 1) At room temperature, ZrO2 is in a monoclinic phase. The phase transition from m-ZrO2 to t-ZrO2 takes place at about 1,447 K. Above 2,650 K, the t-ZrO2 transforms to c-ZrO2 , which is stable up to the melting point at 2,950 K. The c-ZrO2 has an ideal fluorite structure (shown in (Figure 1a). The Zr cations are situated in a face-centered cubic (fcc) lattice, i.e. at the corners of the cubic elementary cell as well as at the halves of the [110] directions. The oxygen anions lie at the quarters of [111] directions, which are the tetrahedral interstitial sites associated with this fcc lattice. The space group is O5 h or Fm3 m. In this structure, each Zr cation is coordinated ..... ReadMore

A Chemosensors is a substance capable of changing color or signal in absorption or emission spectra in the presence of certain specific species with definite concentration which indicate its presence or absence. The information is obtained in the form of a measurable physical signal that is linked with the certain chemical species concentration called analyte [1]. The chemosensors may be broadly classified into two categories. 1. Cation’s sensors 2. Anion’s sensors Cation Sensors Optical cation sensing was initially started for metal ions not having its own spectra in the visible region, has been broadly studied. With the better understanding of host-guest chemistry of crown ethers, it became easier to develop chromogenic sensors for metal ions. Later many outstanding examples of chromophoric and fluorophoric receptors ..... ReadMore
