The development and characterization of the nanosystem are therefore important steps to ensure that the nanosystem has the desired properties to be used for both magnetic hyperthermia and drug delivery. For example, functionalisation of the MNPs with a suitable polymer layer can provide biocompatibility, colloidal stability, drug loading capability and stimuli-responsive behavior. Magnetic nanosystems that respond to both a change in pH and temperature can give spatial and temporal control over the cum să faci față ridurilor forum of the drug, by making use of the acidic pH found in tumor microenvironment and heat generated from the MNPs when exposed to an alternating magnetic field AMF as triggers for the drug release.

Moreover, heat has been found to greatly enhance the intracellular drug uptake and the cytotoxic asian anti aging longevity center pte ltd of many chemotherapeutic drugs, resulting in a synergistic effect of the therapy.

This work aims to develop a dual pH- and thermo-responsive magnetic nanosystem allowing for the triggered release of chemotherapeutic drugs as a consequence of hyperthermia and acidic tumor microenvironment, through breakage of pH and heat labile Schiff base bonds that bind the drug molecules to the polymer. Iron oxide NPs were synthesized by a microwave-assisted co-precipitation method. Finally, the heating performances of the nanohybrids were investigated using a magnetic AC hyperthermia system.

The LCST of the polymer could be easily tuned by varying the initial monomers ratio to be in the hyperthermia temperature range. FTIR analyses confirmed the successful grafting of the polymer by the presence of characteristic carbonyl ester bonds at cm By varying the MNPs to polymer ratio and the pH of the solution during the functionalization step, suspensions with long term colloidal stability could be obtained.

Their potential as magnetic hyperthermia agents was confirmed, demonstrating at the same time the importance of colloidal stability on the heating performances. Vladescu1, M. Badea2, M. Braic1, A.

Therefore, many efforts were directed for finding a solution to obtain a novel implant with high osteoconductive and antibacterial properties, resistant to specific conditions inside the human body.

The hydroxyapatite was proposed to be used for coating the metallic implants to increase their osteoconductive ability. However, the low mechanical strength of hydroxyapatite, the relatively low bone bonding rate, high dissolution rate and low antibacterial properties restrict its use in biomedical applications. The aim of the work was to enhance the antibacterial properties of the hydroxyapatite by Ag addition into its structure. The coatings, with different Ag contents, were deposited on Ti based alloy substrates by magnetron sputtering method.

The influence of the Ag content on the film properties was also analysed. Incorporation of a small amount of Ag into the asian anti aging longevity center pte ltd structure resulted in an improved antibacterial efficacy versus Gram-positive bacteria.

The best hydroxyapatite with Ag content of 0. Further, magnetic scaffolds are envisaged to improve implant fixation when compared to not-magnetic implants. The results clearly indicate that the osteoconductive properties of the scaffolds are well preserved despite the presence of a magnetic component. In contrast, only partial defect healing is achieved within the not magnetic control groups.

These results open new perspectives on the possibility to improve implant fixation and control the bone morphology of regenerated bone by synergically combining static magnetic fields and magnetized biomaterials.

Many of them are composite materials with excellent physical and mechanical properties [1, 2]. Rodents have opposing long pairs of continuously growing incisors.

The front surface of the incisors is enamel; the inner part is softer dentine [3]. The surface of incisors shows characteristic orange-brown color and is identified with the presence of iron [4].

In our study the microstructure and the chemical composition of incisors from the feral coypu Myocastor coypus Molina were investigated using transmission electron microscopy TEM methods and were combined with the mechanical testing experiments.

The layer with variable thickness located at the outer surface of the teeth was detected, possessing a much higher amount of iron compared to the concentration values reported by now. Within the iron-rich surface layer multiple iron containing varieties were identified where iron is detected predominantly in the 3 valence state.

With the present discoveries we will deepen understanding of iron incorporation at the nanoscale level and its effect on the microstructural properties.

Hemicurcuminoids are based on half of the π-conjugated backbone of curcuminoids. The synthesis of a series of such systems and their borondifluoride complexes are described. The emissive character of those dipolar dyes was attributed to an intraligand charge transfer process, leading to fluorescence emission that is strongly dependent on solvent polarity. Quasi quantitative quenching of fluorescence in high polarity solvent was attributed to photoinduced electron transfer.

Those dyes were shown to behave as versatile fluorophores.

Indeed, they display efficient perie curatare fata altex excited fluorescence emission leading to high two-photon brightness values.

Furthermore, they form nanoparticles in water whose fluorescence emission quantum yield is less than that of the dye in solution, owing to aggregation-induced fluorescence quenching. When cos7 living cells were exposed to those weakly-emitting nanoparticles, one- and two-photon excited fluorescence spectra showed a strong emission within the cytoplasm that originated from the individual molecules. Dye uptake thus involved a disaggregation mechanism at the cell membrane which restored fluorescence emission.

This off-on fluorescence switching allows a selective optical monitoring of those molecules that do enter the cell, which offers improved sensitivity and selectivity of detection in bioimaging purposes.
