An overview of the most significative results so far attained in the application of carbon nanotubes, fullerenes and nanodiamonds as chromatographic separation media is presented. In particular, the authors focus on their use in capillary and packed-column gas chromatography, in high performance liquid chromatography and capillary electrochromatography,(More)
UNLABELLED Boron neutron capture therapy (BNCT) is a radiotherapy treatment based on the accumulation in the tumor of a (10)B-containing drug and subsequent irradiation with low energy neutrons, which bring about the decay of (10)B to (7)Li and an α particle, causing the death of the neoplastic cell. The effectiveness of BNCT is limited by the low delivery(More)
New methods for determination of explosive substances as, for example, 2,4,6-trinitrotoluene (TNT), in a rapid way and at low cost are highly required. An electrochemical platform has been here developed with good characteristics of low dimension, fast response, low cost, and high selectivity. It is based on a commercially available screen printed cell with(More)
The exact knowledge of the qualitative and quantitative protein components of rice bran is an essential aspect to be considered for a better understanding of the functional properties of this resource. Aim of the present investigation was to extract the largest number of rice bran proteins and to obtain their qualitative characterization. For this purpose,(More)
A chemically modified gold electrode has been conveniently prepared by binding multiwalled carbon nanotubes (MWCNTs) to which thiol functions have been tethered. The electrode has been characterized by atomic force microscopy and oxidative desorption experiments and gives excellent results for trace determination of As(III) and Bi(III) in natural and(More)
A homochiral, square-shaped, D2 symmetrical nanosized metal-linked macrocycle is able to form stable complexes with ferrocene in polar solvents, with detection achieved by means of multiple outputs (optical/chiroptical spectroscopies and cyclic voltammetry). Selective sensing using chiroptical spectroscopy in the presence of interfering analytes is(More)
In the present work, we show a novel application of pristine and functionalized Multi-Walled Carbon Nanotubes (MWCNTs) as stationary phase in low-cost packed columns for the gas chromatographic separation of alkanes and aromatic hydrocarbons. The MWCNTs were deeply investigated by means of physical and chemical methods, like thermal analysis, IR and atomic(More)
Presented hereafter is the novel application of differently functionalized multi-walled carbon nanotubes (f-MWCNTs) as stationary phases for the GC separation of C(1)-C(5) alcohols and esters. Low-cost packed columns, easily prepared in laboratory, were used with satisfactory results. Depending on the functional groups introduced on the pristine MWCNTs,(More)
Multi-walled carbon nanotubes (MWCNTs) were grafted for the first time by γ-radiation onto silica microspheres in the presence of polybutadiene (PB) as the linking agent, obtaining a novel hybrid material with chromatographic properties, with an alternative approach to the existing procedures. The synthesis involves the one-pot γ-radiation-induced grafting(More)
Amino-terminated alkyl MWCNTs (MWCNTs-R-NH(2)), synthesized by chemical modification of the nanotube skeleton by nucleophilic substitution with 2,2'-(ethylenedioxy)diethylamine, were successfully used as stationary phases for gas chromatographic separation of esters and chloroaromatics. The presence of alkyl chains with polar embedded groups made the(More)
