Alterations to the gene have been associated with Parkinson's disease and alcohol consumption in animals and humans. Furthermore, these disorders are strongly related to anxiety disorders (ADs). Thus, we investigated how the gene might influence anxiety in humans and mice.

Photoinduced electrochemiluminescence (PECL) allows the electrochemically assisted conversion of low-energy photons into high-energy photons at an electrode surface. This concept is expected to have important implications, however, it is dramatically limited by the stability of the surface, impeding future developments. Here, a series of metal-insulator-semiconductor (MIS) junctions, using photoactive n-type Si (n-Si) as a light absorber covered by a few-nanometer-thick protective SiO /metal (SiO /M, with M=Ru, Pt, and Ir) overlayers are investigated for upconversion PECL of the model co-reactant system involving the simultaneous oxidation of tris(bipyridine)ruthenium(II) and tri-n-propylamine.

The (electro)chemical grafting of a polyfluorinated calix[4]arene on gold, polypropylene and glass is reported. The modified surfaces were characterized by ellipsometry, atomic force microscopy (AFM), and by X-ray photoelectron spectroscopy (XPS). A nanometric, robust and uniform monolayer of covalently surface-bound calix[4]arenes was obtained on the three different materials.

Article Synopsis
  • Researchers are developing biosensors for measuring protein concentration and structure, crucial for biomedical applications.
  • A novel approach using FTIR spectroscopy with ATR involves surface functionalization with calix[4]arenes modified with oligo(ethylene glycol) chains to enhance sensor performance.
  • These modified surfaces significantly reduce nonspecific protein adsorption, improving antifouling properties by 85% compared to unmodified surfaces, paving the way for advanced biosensor technology.
