Polydopamine (pDA)-modified iron oxide core-shell nanoparticles (IONPs) are developed and designed as nanovectors of drugs. Reactive quinone pDA enhances the binding efficiency various biomolecules for targeted delivery. Glutathione disulfide (GSSG), an abundant thiol species in cytoplasm, was immobilized on pDA-IONP surface. It serves a cellular trigger to release drug from providing efficient platform delivery system. Additionally, GSSG surface further modified form S-nitrosoglutathione...
Superparamagnetic iron oxide nanoparticles were developed as positron emission tomography (PET) and magnetic resonance imaging (MRI) bimodal agents. These (NPs), with a specific nanoflower morphology, first synthesized simultaneously functionalized 3,4-dihydroxy-l-phenylalanine (LDOPA) under continuous hydrothermal conditions. The resulting NPs exhibited low hydrodynamic size of 90 ± 2 nm. functional groups LDOPA (-NH2 -COOH) successfully used for the grafting molecules interest in second...
Copper-doped zinc oxide nanoparticles (NPs) CuxZn1−xO (x = 0, 0.01, 0.02, 0.03, and 0.04) were synthesized via a sol-gel process used as an active electrode material to fabricate non-enzymatic electrochemical sensor for the detection of glucose. Their structure, composition, chemical properties characterized using X-ray diffraction (XRD), transmission electron microscopy (TEM), Fourier-transform infrared (FTIR) Raman spectroscopies, zeta potential measurements. The characterization sensors...
The aim of this study was to investigate the influence surface charge and coating Superparamagnetic Iron Oxide Nanoparticles (SPIONs) on their in vitro vivo behaviors.Neutral negatively-charged PEG-based SPIONs were synthesized compared Resovist®, a carboxydextran-based SPION currently used clinics.Their cytotoxicity, cell internalization, potential as contrast agents for magnetic resonance imaging assessed.Neutral pegylated internalized less readily by reticuloendothelial system showed...
In the present article, we report synthesis of titanate nanotubes and nanoribbons with controlled morphology, structure, chemical composition depending on main parameters synthesis. Hydrothermal processing time, grain size precursor, type agitation, acid treatment were investigated, principal controversies mentioned in literature such as nanotube crystallographic their composition, impact are discussed. These may be due to heterogeneities all samples rarely considered literature....
Actively contractile cardiomyocyte (CM) monolayer represents an interesting tool to study both cardiac diseases and injuries. However, this model is poorly transfectable with conventional agents. Consequently, there a need develop new carriers that could overcome problem. Titanate nanotubes (TiONts) be potential candidate due possibly higher cell uptake as direct consequence of their shape. On the basis rationale, TiONts were assessed for cytotoxicity internalization pathways. Cytotoxicity...
The functionalization of superparamagnetic iron oxide nanoparticles (SPIOs) by meso-2,3-dimercaptosuccinic acid (DMSA) was investigated. Under ambient conditions, the thiol groups from DMSA are not stable and do allow a direct without storage in stringent conditions or chemical regeneration free thiols. In this study, we have developed protocol based on poly(ethylene glycol) (PEG) grafting SPIO prior to anchoring. We observed that PEG helps increase stability under conditions. functionalized...
In the present study, we report dispersion of titanate nanotubes (TiONts) via polymer grafting (PolyEthylene Glycol, PEG) or adsorption (polyethylene imine, PEI) where different TiONts/polymer ratios have been investigated. The TiONts/PEI and TiONts/PEG nanohybrids were characterized by scanning transmission electron microscopy as well zeta potential measurements in order to determine both their state stability water (at pH for zetametry). nature chemical bonds at surface these was...
Nanohybrids based on titanate nanotubes (TiONts) were developed to fight prostate cancer by intratumoral (IT) injection, and particular attention was paid their step-by-step synthesis. TiONts synthesized a hydrothermal process. To develop the customengineered nanohybrids, surface of coated beforehand with siloxane (APTES), coupled both dithiolated diethylenetriaminepentaacetic acidmodified gold nanoparticles (Au@DTDTPA NPs) heterobifunctional polymer (PEG3000) significantly improve...
For the first time, titanate nanotubes (TiONts) coated with USPIO (ultrasmall superparamagnetic iron oxide) without polymer functionalization and directly obtained during TiONts formation is reported. The coating of these tubes was performed hydrothermal synthesis. After this treatment, in strongly basic conditions, particles kept their structure magnetic properties while size distribution slightly increased. By coupling zeta-potential measurements TEM observations at different pH it...
