Preparation, loading, and cytotoxicity analysis of …

Polymer nanotubes and multi‐walled carbon nanotubes (MWCNTs) (Sigma‐Aldrich) were suspended in cell culture media (containing serum) at various concentrations. The media were removed from the seeded well‐plates (C6 glioma and astrocytes), and 100 μL of the various dilutions was added and incubated for 24 h.

Synthesis of oxygen functionalized carbon nanotubes …

Oxygen functionalized carbon nanotubes synthesized by surface acid treatment were used to improve the dispersion properties of active materials for catalysis. Carbon nanotubes have gained attention as a support for active materials due to their high specific surface areas (400–700 m2 …

Interactions of Carbon Nanotubes and Carbon …

A broader use of carbon nanomaterials increases the risk of their inhalation as aerosol dispersed in the air. Inhaled nanometer-sized particles are known to penetrate to the pulmonary region where they interact with the lung surfactant as the first barrier they meet and eventually penetrate to the surface of the cellular layer. This study presents the results of experimental studies of ...

Biodegradation of Carbon Nanotubes, Graphene, and …

Carbon nanotubes (CNTs), graphene (GRA), and their derivatives are promising materials for a wide range of applications such as pollutant removal, enzyme immobilization, bioimaging, biosensors, and drug delivery and are rapidly increasing in use and increasingly mass produced. The biodegradation of carbon nanomaterials by microbes and enzymes is now of great importance for both reducing their ...

Binding of blood proteins to carbon nanotubes …

With the potential wide uses of nanoparticles such as carbon nanotubes in biomedical applications, and the growing concerns of nanotoxicity of these engineered nanoparticles, the importance of nanoparticle–protein interactions cannot be stressed enough. In this study, we use both experimental and theoretical approaches, including atomic force microscope images, fluorescence spectroscopy, CD ...
