Amphiphilic COSAN and I2-COSAN crossing synthetic lipid membranes: planar bilayers and liposomes
The boron-rich cobaltabisdicarbollide (COSAN) and its 8,80-I2 derivative (I2-COSAN), both of purely inorganic nature, are shown to cross through synthetic lipid membranes. These results reveal unexpected properties at the interface of biological and synthetic membranes
New Labour?new renaissance
This paper explores the term ?urban renaissance? in relation to the historiography of the Renaissance of the 15th and 16th centuries in Italy. It examines the place of the Renaissance in cultural history and considers how it has, since its inception, been utilised by writers to reflect on the present. The paper situates the urban renaissance within the context of New Labour rhetoric at the time of the Millennium. It argues that the idea of renaissance can, in this instance, be connected to a kind of millenarianism that was reflected in public rhetoric regarding the city and in a number of building projects
Preparation and characterization of au nanoparticles capped with mercaptocarboranyl clusters
The preparation of 3–4 nm and 10 nm gold nanoparticles capped with neutral carborane-based mercaptocarboranes, via two different preparative routes, is reported. The resulting boron-enriched nanomaterials exhibit complete dispersibility in water, opening the way for the use of these monolayer protected clusters (MPCs) in medical applications, such as boron neutron capture therapy (BNCT). These newly prepared MPCs have been characterized by FTIR, 1H and 11B NMR spectroscopy, UV-visible, centrifugal particle sizing (CPS), and, in some cases, inductively coupled plasma atomic emission spectrometry (ICP-AES). Water dispersibility exhibited by these MPCs allowed the study of the cellular uptake by HeLa cells
