The overall objective of BONSAI project (FP6, EC) is the development of ultrasensitive bio-imaging techniques based on novel multifunctional nanoparticles (NPs) with tailored optical and magnetic properties for visualizing complex cellular structures (in tissues and organs), receptors, tumour cells and masses. An important aspect to take into consideration(More)
OBJECTIVES This study evaluated the immediate and 6-month resin-dentin micro-bond strength (microTBS) of one-step self-etch systems (Adper Prompt L-Pop [AD] 3M ESPE; Xeno III [XE] Dentsply De Trey; iBond [iB] Heraeus Kulzer) under different application modes. MATERIALS AND METHODS Dentin oclusal surfaces were exposed by grinding with 600-grit SiC paper.(More)
OBJECTIVES To evaluate the use of two alternative modes of application (double-application and placement of a hydrophobic resin coat) compared with the manufacturers' directions on the microtensile bond strength (microTBS) of one-step, self-etch systems to enamel and dentin. MATERIALS AND METHODS Resin composite buildups were bonded to the buccal and(More)
The EC BONSAI Project intends to develop multifunctional nanoparticles with tailored optical and/or magnetic properties for visualizing complex cellular structures (in tissues and organs), receptors, tumor cells and masses. In this framework, here we will report on recent advances on the preparation of luminescent silicon nanoparticles, magnetic iron oxide(More)
