abstract = {GM3-ganglioside is known to be involved in melanoma proliferation. In order to modulate metastatic-related events, we have functionalized multi-walled carbon nanotubes (MWCNTs) with multiple copies of a GM3-lactone mimetic. The MWCNTs proved to guarantee the appropriate spatial arrangement of the mimetic allowing a stronger inhibition of migration and invasiveness of human melanoma (A375) cells compared to other multivalent constructs reported before. In addition, the effect of the multivalent tubular conjugate on the inhibition of specific tyrosine kinases, which are associated with the ganglioside complexes within the membrane domains, was demonstrated. Finally, the short-term fate of the conjugate was assessed, for the first time, by means of the 1H NMR relaxometry technique by exploiting the signal arising from the CNTs.},

abstract = {The high versatility of graphene has attracted significant attention in many areas of scientific research from electronics to physics and mechanics. One of the most intriguing utilisation of graphene remains however in nanomedicine and synthetic biology. In particular, the last decade has witnessed an exponential growth in the generation of novel candidate therapeutics of multiple biological activities based on graphene constructs with small molecules, such as anti-cancer drugs. In this Digest, we summarise the different synthetic strategies and routes available to fabricate these promising graphene conjugates and the opportunities for the design of multi-functional tools for synthetic biology that they offer.},

abstract = {Carbon nanotubes are novel nanomaterials that are thought to offer potential benefits to a variety of biomedical and clinical applications. In this study, the treatment of a human lung carcinoma model in vivo using siRNA sequences leading to cytotoxicity and cell death is carried out using either cationic liposomes (DOTAP:cholesterol) or amino-functionalized multi-walled carbon nanotubes (MWNT - NH(+)(3)). Validation for the most cytotoxic siRNA sequence using a panel of human carcinoma and murine cells reveals that the proprietary siTOX sequence is human specific and can lead to significant cytotoxic activities delivered both by liposome or MWNT - NH(+)(3) in vitro. A comparative study using both types of vector indicates that only MWNT - NH(+)(3):siRNA complexes administered intratumorally can elicit delayed tumor growth and increased survival of xenograft-bearing animals. siTOX delivery via the cationic MWNT - NH(+)(3) is biologically active in vivo by triggering an apoptotic cascade, leading to extensive necrosis of the human tumor mass. This suggests that carbon-nanotube-mediated delivery of siRNA by intratumoral administration leads to successful and statistically significant suppression of tumor volume, followed by a concomitant prolongation of survival of human lung tumor-bearing animals. The direct comparison between carbon nanotubes and liposomes demonstrates the potential advantages offered by carbon nanotubes for the intracellular delivery of therapeutic agents in vivo. The present work may act as the impetus for further studies to explore the therapeutic capacity of chemically functionalized carbon nanotubes to deliver siRNA directly into the cytoplasm of target cells and achieve effective therapeutic silencing in various disease indications where local delivery is feasible or desirable.},
