A water-based functionalized nanofluid was made by surface functionalizing the ordinary silica nanoparticles. The functionalized nanofluid can keep long-term stability. and no sedimentation was observed. The functionalized nanofluid as the working fluid is applied in a thermosyphon to understand the effect of this special nanofluid on the thermal performance of the thermosyphon. The experiment ...

Designer self-assembling peptide nanofiber hydrogel scaffolds have been considered as promising biomaterials for tissue engineering because of their excellent biocompatibility and biofunctionality. Our previous studies have shown that a novel designer functionalized self-assembling peptide nanofiber hydrogel scaffold (RLN/RADA16, LN-NS) containing N-terminal peptide sequence of link protein (li...

Multiplexed SERS imaging of receptor proteins on the surface of mammalian cells has been carried out using functionalized silver nanoparticles. Deconvolution of four differently functionalized nanoparticles is readily achieved, and using this approach, receptor co-localization can be probed and protein-protein interactions can be elucidated at the surface of cells.

Water-soluble carborane functionalized nanoparticles also co-functionalized with targeting antibodies have been prepared. We demonstrate tumour cell targeting with anti-EGFR antibodies and delivery of a high concentration of boron using SERS imaging. This suggests these materials have a therapeutic potential in addition to multimodal imaging capabilities.

Three kinds of redox-mediated behavior were realized at an azobenzene-functionalized electrode, which has great potential for application in the field of molecular devices. According to these results, the functionalized electrode could act as either a cathodic molecular rectifier or anodic molecular rectifier.

By Ryan D. Ross The accumulation of microdamage has been linked to clinical bone fragility and increased fracture susceptibility. Damage is normally repaired by a cellular remodeling process. However, a fracture may occur if damage accumulates faster than it can be repaired. Current methods for imaging microdamage are inherently invasive, destructive and two-dimensional. The development of a ta...

Monodisperse small iron oxide nanoparticles functionalized with dendritic polyglycerol (dPG) or dendritic polyglycerol sulfate (dPGS) are prepared. They are highly stable in aqueous solutions as well as physiological media. In particular, oleic acid capped iron oxide particles (core diameter = 11 ± 1 nm) were modified by a ligand exchange process in a one pot synthesis with dPG and dPGS bearing...

Conventional methods used to image and quantify microdamage in bone tissue are limited to thin histological sections. Therefore recent studies have begun to investigate methods for non-destructive, three-dimensional (3-D) detection and imaging of microdamage in bone tissue. The objective of this study was to investigate gold nanoparticles (Au NPs) as a potential damage-specific X-ray contrast a...

We describe a new oblique-incidence reflectivity difference (OI-RD) scanning microscope for high-throughput screening, in microarray format on functionalized glass slides, small-molecule compound libraries for protein ligands. The microscope employs a combination of scan mirror for y-scan and single-axis translation stage for x-scan. For a printed microarray with over 10,000 features, each of 1...

Maleimide-functionalized polystyrene (PSMA-SiO2/TiO2) hybrid nanocomposites were prepared by sol-gel reaction starting from tratraethoxysilane (TEOS) and titanium isopropoxide in the solution of polystyrene maleimide in 1,4-dioxane. The hybrid films were obtained by the hydrolysis and polycondensation of TEOS and titanium isopropoxide in maleimide-functionalized polystyrene solution followed by...
