Monodisperse magnetic nanoparticles (MNPs) were synthesized by thermal decomposition of iron-oleate and functionalized with silanes bearing various functional groups such as amino group (NH2), short-chain poly(ethylene glycol) (PEG), and carboxylic group (COOH). Then, silanes-functionalized magnetic nanoparticles (silanes-MNPs) were incubated in cell culture medium plus fetal calf serum to inve...

The programmed self-assembly of gold nanoparticles (AuNPs) with controlled surface chemistry has attracted considerable attention for their potential applications in drug delivery and medical diagnosis. A number of specific biomolecular recognition motifs such as complementary oligonucleotide hybridization, biotin-avidin binding and enzymatic catalytic reactions have been extensively exploited ...

NH2+ implantation was performed on multiwalled carbon nanotubes (MWCNTs) prepared by chemical vapor deposition. The hemocompatibility of MWCNTs and NH2+-implanted MWCNTs was evaluated based on in vitro hemolysis, platelet adhesion, and kinetic-clotting tests. Compared with MWCNTs, NH2+-implanted MWCNTs displayed more perfect platelets and red blood cells in morphology, lower platelet adhesion r...

A number of carbobenzoxy-dipeptide-amides raise the bilayer to hexagonal phase transition temperature of dielaidoylphosphatidylethanolamine (stabilizes the bilayer). The potency of the peptides in stabilizing the bilayer phase is Z-Tyr-Leu-NH2 = Z-Gly-Phe-NH2 greater than Z-Ser-Leu-NH2 greater than Z-Gly-Leu-NH2 greater than Z-Gly-Gly-NH2. A linear correlation was found between the respective H...

Multi-modal imaging-guided synergistic photodynamic therapy (PDT) and photothermal (PTT) show great benefits in cancer treatment. The phototheranostics with near-infrared (NIR) absorption, high reactive oxygen species (ROS) generation conversion efficiency is highly desirable. Here, we designed synthesized an “acceptor-donor-acceptor” (A-D-A) structured molecule named IDCIC, strong absorbance t...

NH2 + implantation was performed on multiwalled carbon nanotubes (MWCNTs) prepared by chemical vapor deposition. The hemocompatibility of MWCNTs and NH2 -implanted MWCNTs was evaluated based on in vitro hemolysis, platelet adhesion, and kinetic-clotting tests. Compared with MWCNTs, NH2 -implanted MWCNTs displayed more perfect platelets and red blood cells in morphology, lower platelet adhesion ...

It was considered, a priori, that the isolation of the tridecapeptide, neurotensin, might have inadvertently sllowed the hydrolysis of either the [Gln4]- or the [Leu13-NH2]-moieties. Neurotensin and its three acid and amide analogs, i.e., [Gln4]-neurotensin, neurotensin-NH2, and [Gln4]-neurotensin-NH2 were synthesized. Neurotensin and [Gln4]-neurotensin were indistinguishable by the hypotensive...
