Synthesis and characterization of core-shell structure silica-coated Fe29.5Ni70.5 nanoparticles

In view of potential applications of magnetic particles in biomedicine and electromagnetic devices, we made use of the classical Stober method base-catalysed hydrolysis and condensation of tetraethoxysilane (TEOS) to encapsulate FeNi nanoparticles…

Generation of new fluorophore by Click chemistry: synthesis and properties of beta-cyclodextrin substituted by 2-pyridyl triazole

2-Pyridyl triazole substituted P-cyclodextrins, formed by a HUisgen [2+3] cycloaddition reaction between per-(6-azido)-beta-cyclodextrins and 2-ethynylpyridine, exhibited interesting solvent-polarity dependent fluorescence properties and acted as…

Étude de dérivés de Bodipy à l'état solide et en matrice polymère : vers la réalisation de nanocapteurs

La fluorescence d'assemblées de dérivés de Bodipy a été étudiée afin de réaliser des nanocapteurs. Les nanoobjets envisagés sont soit des nanocristaux soit des particules de polystyrène en suspension dans l'eau, i.e. des nanolatex. Dans un premier…

Redox-modulated recognition of tetrazines using thioureas

Reduced 1,2,4,5-tetrazines serve as two-point hydrogen-bonding acceptors for thiourea. This host-guest system does not exhibit significant binding in the neutral state, making the complex an electrochemical "on/off" switch.

Molecular nanocrystals grown in sol-gel thin films for ultrabright chemical sensor applications

Polyaromatic dyes were used to synthesize molecular nanocrystals in sol-gel thin films for sensor applications. Fluorescence Confocal Microscopy (FCM) and Transmission Electron Microscopy (TEM) experiments showed the advantages of our…

Analysis of the gelation process of hybrid silica-zirconia and silica-titania gels using two different grafted electroactive probes

Several conditions for the sol-gel polymerisation of hybrid silica-zirconia and silica-titania have been studied using specially tailored electrochemical probes. One of the probes has been designed to bind to the silica backbone, while the other has…
