The prion protein (PrPC) is a glycoprotein that in mammals, differently from avians, can lead to prion diseases, by misfolding into a beta-sheet-rich pathogenic isoform (PrPSc). Mammal and avian… (More)
The prion protein (PrPc) is a copper-binding glycoprotein that can misfold into a β-sheet-rich and pathogenic isoform (PrPsc) leading to prion diseases. The first non-mammalian PrPc was identified in… (More)
Potentiometric and spectroscopic (UV-Vis, CD and EPR) studies were carried out on copper(II) complexes with chicken prion protein N-terminal fragments, Ac-(PHNPGY)(4)-NH(2), and the mutated residue,… (More)
The ternary copper(II) complex of 6-deoxy-6-[(2-(4-imidazolyl)ethyl)amino]cyclomaltoheptaose (CDhm) and L-tryptophanate (L-TrpO(-)) was characterized by ESR and X-ray diffraction. The solid state… (More)
The possibility of using capillary electrophoresis-electrospray ionisation (ESI)/MS to separate and quantify cobalt and iron was explored. It was necessary to tackle and overcome problems from… (More)
The diaminotrehalose-capped derivative of β-CD, a new member of hemispherodextrins, was synthesized and characterized by NMR spectroscopy. Its protonation constants were determined by potentiometry,… (More)
Gold nanoparticles show important properties owing to their electronic structures. A limitation of some gold nanoparticles is that they either show surface plasmons or luminescence. The increase in… (More)
The systems that the 3-amino derivative of beta-cyclodextrin (CD3NH2) forms with the proton, the copper(II) ion and each of the enantiomers of certain amino acids (alanine, phenylalanine, tyrosine… (More)
The review focuses on the role of ionic or ionisable single isomer derivatives (SIDs) of cyclodextrins on the separation of chiral analytes in capillary electrophoresis (CE), covering the period… (More)
The design of molecular architectures able to transfer mass to each other is a field of extreme importance. In the present study it is shown that two especially designed covalently assembled… (More)
