“…47 A recent report suggested that exposure to electromagnetic waves promotes CNT entry not only into the cytoplasm of cells, but also into the nucleus. 50 Our present findings suggest a similarity between the modes of action of humic macromolecules with analogous biomacromolecules/proteins. The macromolecule acts as shuttle-like agent to enhance the permeability of [CNT/ organic] into the internal cellular compartments.…”

Mixtures of multi-walled carbon nanotubes (MWCNTs) with natural humic acids (Leonardite humic acid, LHA) or humic acid-like polycondensates (HALP) were evaluated, for the first time, about their potential genotoxic and cytotoxic effects in cultured human lymphocytes. The genotoxic evaluation of the tested materials, either separately or in combination, for the detection of micronuclei (MN) in the cytoplasm of interphase cells, was performed using the cytokinesis block micronucleus (CBMN) assay. A comparative analysis of the genotoxicity and cytotoxicity reveals that in the tested concentrations, the [MWCNTs + LHA] mixture is more genotoxic and slightly more cytotoxic than the [MWCNTs + HALP] mixture. MN induction observed in human lymphocytes demonstrates that humic substances enhance the genotoxic effects of MWCNTs. In addition, the present data highlight aso far unforeseenpotential genotoxic effect as the result of both clastogenic and aneugenic actions of the particular mixtures on human lymphocytes.Environ. Sci.: Nano This journal is A genotoxicity mechanism of multi-walled carbon nanotubes (MWCNTs) interacting with humic acids (HAs) is revealed. The interfacial properties of MWCNT-HA formations were characterized with ATR-FTIR, Atomic Force Microscopy and Dynamic Light Scattering. Using natural and synthetic/metal-free humic polymers, the mechanisms of colloidal dispersion are correlated with the revealed genotoxicity. Moreover, the geno-vs. cytotoxicity phenomena are quantitatively distinguished. These phenomena originate from the action of humic macromolecules as "chaperones" that shuttle MWCNTs into the cell compartments.

“…Excitation of CNTs by exposure to an appropriately tuned radio frequency field has been shown to permeabilize cell membranes to allow cell uptake of normally impermeable drugs or gene expression vectors both in in vitro and in vivo in brain tissue [101]. Similarly, treatment of cancer cells or tumor bearing mice using SWNTs chemically conjugated with platinum-based chemotherapeutics [102] or loaded with doxorubicin by hydrophobic interactions [103] and combined with NIR mediated photothermal heating were significantly more effective than either therapy alone.…”

Thermal tumor ablation therapies are being developed with a variety of nanomaterials, including single-and multiwalled carbon nanotubes. Carbon nanotubes (CNTs) have attracted interest due to their potential for simultaneous imaging and therapy. In this review, we highlight in vivo applications of carbon nanotube-mediated thermal therapy (CNMTT) and examine the rationale for use of this treatment in recurrent tumors or those resistant to conventional cancer therapies. Additionally, we discuss strategies to localize and enhance the cancer selectivity of this treatment and briefly examine issues relating the toxicity and long term fate of CNTs.

“…Similarly, oxidative stress-induced DNA damage was also observed after an intraperitoneal administration of IONPs in mice 18,40 . However, few studies also reported no genotoxicity induced by IONPs 41,42 . In our study, we found that IONPs exposure to Wistar rats increases the frequency of both chromosomal aberration and micronucleus induction along with increased DNA damage in a dose-dependent manner.…”

Iron oxide nanoparticles (IONPs) are known to induce cytotoxicity in various cancer cell lines through the generation of reactive oxygen species (ROS). However, the studies on its potential to induce toxicity in normal cell lines and in vivo system are limited and ambiguity still exists. Additionally, small molecules are known to interact with the DNA and cause damage to the DNA. The present study is designed to evaluate the potential interaction of IONPs with DNA along with their other toxicological effects and subsequent attenuation by thymoquinone both in vitro (primary lymphocytes) and in vivo (Wistar rats). IONPs were characterized by TEM, SEM-EDS, and XRD. The results from DNA interaction studies showed that IONPs formed a complex with DNA and also got intercalated between the base pairs of the DNA. The decrease in percent cell viability of rat’s lymphocytes was observed along with an increase in ROS generation in a dose-dependent manner (50, 100, 200, 400 and 800 μg/ml of IONPs). The genetic damage in in vivo might be due to the generation of ROS as depletion in anti-enzymatic activity was observed along with an increase in lipid peroxidation in a dose–dependent manner (25, 50, 100 mg/kg of IONPs). Interestingly, supplementation of thymoquinone in combination with IONPs has significantly ( P < 0.05) attenuated the genetic and oxidative damage in a dose-dependent manner both in vitro and in vivo . It can be concluded that thymoquinone has the potential to attenuate the oxidative stress and genetic toxicity in vitro and in vivo .
