We have synthesized a new macromolecular architecture, (PAMAM)-CD8 , which consists of eight β-cyclodextrin units (β-CD) attached to a generation 1 poly(amidoamine) (PAMAM) dendrimer through a disulfide bond, which can be cleaved under reducing conditions. This system shows a pronounced hosting capability towards Gd(III) chelates functionalized with… (More)
Perthiolated β-cyclodextrin-based nanocapsules incorporating diaquo Gd(III)-complexes represent a promising new type of bioresponsive MRI contrast agent, showing a pronounced relaxivity change upon degradation in a reducing environment.
prohibitive for the embedded domain, once they dissipate too much power and energy. In this paper we propose a low power hierarchical network topology with GALS interfaces, allowing each cluster operates in a specific frequency. The clusters are composed by crossbar devices and the number of cores allocated for each cluster is defined considering floorplan… (More)
N,N'-Dibenzyl-6-hydroxymethyl-6-nitroperhydro-1,4-diazepine was converted into a nitronate via retro-Henry reaction, followed by either Michael reaction with several acrylic derivatives or Mannich reaction with different amines, thus leading to 6-substituted 6-nitroperhydro-1,4-diazepines. The tandem retro-Henry/Mannich reaction was also carried out using… (More)
A new class of nanovesicles formed by the self-assembly of amphiphilic Janus dendrimers, dendrimersomes, loaded with hydrophilic or amphiphilic magnetic resonance imaging chelates shows promising properties as a novel, efficient and versatile nanoplatform for biomedical imaging.
