Fluorinated benzosiloxaboroles-silicon congeners of benzoxaboroles, were synthesized and tested as molecular receptors for mono- and disaccharides. The receptors differed in the Lewis acidity of the boron center as well as in the number of potential binding sites. The calculated stability constants indicated different binding affinity of benzosiloxaborole derivatives towards selected saccharides, enabling their classification using a receptor array-based sensing.

CuO and V₂O₅ graphene quantum tunneling composites (GQTC) presented in this article were produced and their sensory properties were analyzed. The composites were synthesised using two stage high-power milling process, which resulted in materials that have good temeprature and pressure sensory properties. Described production process defines internal structure of materials such that when used as sensor in the desired range, it exhibits a strong percolation effect.

Gold electrodes were functionalized with thiolated phenylboronic acids or by sequential immobilization of alkanethiols with terminal carboxylic groups and conjugation with aminophenylboronic acids. The stepwise assembly of organic molecules was characterized by several voltammetric techniques with systematic monitoring of surface coverage of organic molecules anchored to the gold electrodes. The receptor properties and applicability of the obtained monomolecular layers for the voltammetric detection of fructose and fluoride ions in solution were evaluated.

Article Synopsis
  • Esophagus or stomach resection remains a primary treatment for patients with malignant disease, despite a risk of complications like anastomotic fistulas occurring in 4-27% of cases.
  • The study focuses on the use of covered stent placement for treating postoperative anastomotic fistulas, noting that previous conservative treatments failed.
  • In a sample of six patients, covered stent placement under X-ray control led to significant improvement, reduced secretion from fistulas, and all patients survived after 30 days, indicating this method may enhance treatment outcomes and quality of life.
