The development of efficient contrast agents for cell labelling coupled with powerful medical imaging techniques is of great interest for monitoring cell trafficking with potential clinical applications such as organ repair and regenerative medicine. In this paper, functionalised multi-walled carbon nanotubes (MWNTs) were engineered for cell labelling in T1-weighted MRI applications. These sophisticated...
Carbon nanotubes have attracted particular attention in antiviral therapy and recently have been explored as HIV inhibitors through structure-based design. In order to prove their in vitro ability to interact with viral enzymes and to act as HIV inhibitors, we have studied the antiviral potentiality of highly hydrophilic and dispersible carboxylated multi-walled carbon nanotubes (ox-MWCNT) and the...
Though having passed the second decade since their discovery, carbon nanotubes (CNTs) still hold promise in different fields, and many steps forward have been done. However, one major limit is given by their lack of solubility, which still represents a challenge, given the need to properly handle the material for many applications. The most efficient strategies to solve this problem often rely on...
Single layers of C 60 mono- and bis-adducts have been obtained by functionalizing an acid-terminated self-assembled monolayer (SAM) of thiols on gold. X-ray photoelectron spectroscopy demonstrated the grafting onto the SAM by covalent bonding, via the formation of an amide bond, while cyclic voltammetry and electrochemical impedance spectroscopy provided information on the redox properties...
Fullerene derivatives have interesting biological activities that make them good candidates for applications in medicinal chemistry. However, the development of these applications is hampered by the fact that fullerene derivatives are insoluble in water and polar media. We present here a general method for the preparation of N-functionalized fulleropyrrolidines with solubilizing groups via 1,3-dipolar...
1,3-Dipolar cycloaddition of azomethine ylides to C 60 generates a family of fullerene derivatives, colloquially termed fulleropyrrolidines. In this paper, we report the synthesis and the electrochemical properties of fulleropyrrolidine and fulleropyrrolidinium ion derivatives. Cyclic voltammetry measurements, performed using ultramicroelectrodes at -60 o C with scan rates as...
