“…40). 41 In this study, the hybrid concentrations ranged from 73 to 110 lg/ml for the SWNT-Au hybrids with the 10 nm GNP hybrids demonstrating the highest concentration of 110 lg/ml followed by 60 nm (82 lg/ml) and 30 nm (74 lg/ml). S1(a) The final concentration of the hybrid particles was determined with UV-visible spectroscopy (Cary5000 machine) as previously demonstrated for CNTs.…”

Improvement of emission characteristics uniformity of carbon nanotube field emission display by surface treatment J.The development of multifunctional hybrid nanostructures that can be remotely activated is an attractive strategy for a diverse range of applications ranging from electronics, cancer therapeutics, and drug delivery platforms to sophisticated biosensors. In this study, the authors examined the systematic capture of biomolecular targets onto single-walled carbon nanotubes (SWNTs), sitespecific labeling with gold nanoparticles (GNPs) of three different sizes (10, 30, 60 nm), and the subsequent effects upon exposure to 1064 nm near-infrared (NIR) laser irradiation. The authors demonstrate that the SWNT-GNP hybrids containing the smallest GNPs experience greater heating and subsequent GNP release upon NIR laser irradiation compared to SWNT surfaces modified with larger 60 nm GNPs. The authors hypothesize that the greater attachment efficiency of the smaller GNPs to the biomolecules allows increased heat transduction. Therefore, it is possible to physically modify the surface of hybrid nanostructures remotely via NIR laser irradiation. It is anticipated that targeted NIR strategies will benefit from the robustness of novel material combinations, such as SWNT-GNP hybrid nanostructures, as well as interchangeable biomolecular ligands.

“…Two types of NP dispersions were prepared at a concentration of 1 mg/mL: dispersed in water and dispersed in 1 % w/v Pluronic F108 aqueous solution, according to two distinct protocols of dispersion: stirring and sonication probe (Mejia et al 2011;Piret et al 2010;Vankoningsloo et al 2010). The water dispersion was prepared by adding the NPs directly to water at room temperature.…”

The evolution of the particle size distribution and the surface composition of silicon carbide and titanium carbide nanoparticle (NP) dispersions were studied. The pre-dispersions were prepared using two commonly used protocols for dispersion: stirring and sonication. Two dispersants were investigated (water and Pluronic F108 1 %) at two stages: predispersion and during in vitro assays. Our data show that for each tested condition, different time-dependent results for the surface chemical composition as well as size and percentage of the agglomerates and the primary particles are observed. De-agglomeration and successive or simultaneous cleaning-wrapping cycles of the nanomaterial are observed and are related to the dispersion method and the medium as well as to the chemical stability of the NP surface. Biological response during in vitro assessment was also performed for one given pre-dispersion time condition and demonstrates that the preparation method significantly alters the results.

“…Such agglomeration normally degrades the properties of CNT-reinforced materials. Hence, a considerable number of studies focused on the dispersion of CNTs since CNTs were first developed [31,32]. Specifically, the dispersion of CNTs in a dry state is not simply achieved by conventional techniques.…”
