Superior sensing performance of multi-walled carbon nanotube-based electrodes to detect unconjugated bilirubin

Giovanni De Micheli, Sandro Carrara, Irene Taurino

The direct electrochemical behaviour of bilirubin in the physio-pathological concentration range and at physio- logical pH was investigated by cyclic voltammetry. Nanostructured electrodes with a thin film of multi-walled carbon nanotubes exhibited a highe ...

Electrochemical Detection of Anti-Breast-Cancer Agents in Human Serum by Cytochrome P450-Coated Carbon Nanotubes

Giovanni De Micheli, Sandro Carrara, Camilla Baj-Rossi

We report on the electrochemical detection of anti-cancer drugs in human serum with sensitivity values in the range of 8–925 nA/µM. Multi-walled carbon nanotubes were functionalized with three different cytochrome P450 isoforms (CYP1A2, CYP2B6, and CYP3A4) ...

Sensitization of fullerenes by covalent attachment of a diketopyrrolopyrrole chromophore

Jacques-Edouard Moser, Natalie Renuka Banerji

In an effort to develop new materials for organic solar cell applications, we have synthesized triads of 3,6-dithien-2-yl-2,5-dialkylpyrrolo[3,4-c]pyrrole-1,4-dione (DTDPP) covalently linked at the nitrogen positions to two [6,6]-phenyl-C61-butyric acid es ...
