The development of nanoscopic hybrid materials equipped with " molecular gates " showing the ability of releasing target entrapped guests upon the application of an external trigger has attracted great attention and has been extensively explored during recent years. [1] These nanodevices are composed of two subunits, namely, a suitable support and certain(More)
Within nanotechnology, gold and silver nanostructures have unique physical, chemical, and electronic properties [1,2], which make them suitable for a number of applications. Moreover, biosynthetic methods are considered to be a safer alternative to conventional physicochemical procedures for both the environmental and biomedical applications, due to their(More)
pH-sensitive gated mesoporous silica nanoparticles have been synthesized. Increased extracellular pH and internalization into living yeast cells triggered molecular gate aperture and cargo release. Proper performance of the system was demonstrated with nanodevices loaded with fluorescein or with the antifungal agent tebuconazole. Interestingly, nanodevices(More)
The following text presents the results of a content analysis study focusing on the image of immigration in Spanish prime-time television fiction with Cultivation theory as a reference. Two representative samples were recorded in 2011, out of the six main national channels. The analysis derived from the analysis of these fiction programs (series and films)(More)
The synthesis of capped mesoporous silica nanoparticles (MSN) conjugated with an antibody (AB) as a gatekeeper has been carried out in order to obtain a delivery system able to release an entrapped cargo (dye) in the presence of a target molecule (antigen) to which the conjugated antibody binds selectively. In particular, MSN loaded with rhodamine B and(More)
