Primary microglia maintain their capacity to function despite internalisation and intracellular loading with carbon nanotubes

Peripheral blood lymphocytes are able to maintain their viability and basic function in normal urine

Background: Similar to inflammatory cells, peripheral blood mononuclear cells (PBMCs) can also infiltrate in to kidney and urinary tracts and subsequently excreted by urine. In this study we determined the viability rate and response to phytohemagglutinin-A (PHA) of human PBMCs in normal urine. Methods: A number of 1×106 ficoll-hypaque isolated PBMCs were dispensed in 1 ml normal urine...

Drug-loading capacity and nuclear targeting of multiwalled carbon nanotubes grafted with anionic amphiphilic copolymers

In this study, three types of hybrid nanotubes (NTs), ie, oxidized multiwalled carbon NTs (COOH MWCNTs), heparin (Hep)-conjugated MWCNTs (Hep MWCNTs), and diblock copolymer polyglycolic acid (PGA)-co-heparin conjugated to MWCNTs (PGA MWCNTs), were synthesized with improved biocompatibility and drug-loading capacity. Hydrophilic Hep substituents on MWCNTs improved biocompatibility and acted as n...

Carbon Nanotubes and Their Composites

Ballistic resistance capacity of carbon nanotubes

Carbon nanotubes have high strength, light weight and excellent energy absorption capacity and therefore have great potential applications in making antiballistic materials. By examining the ballistic impact and bouncing-back processes on carbon nanotubes, this investigation shows that nanotubes with large radii withstand higher bullet speeds and the ballistic resistance is the highest when the...

Study on interaction between carbon nanotubes (CNTs) as nano carrier for loading and delivery of Methotrexate

The Methotrexate delivery by carbon nanotubes (CNTs) and the structural changes of drugcombination upon the carbon nanotubes and bio thermodynamic of the drug have been studied by molecularcomputational methods. Computational molecular methods have been fulfilled by molecular mechanics methods with four force field, and semi empirical with all methods. We investigate different param...
