Hepatoprotective effect of fullerenol/doxorubicin nanocomposite in acute treatment of healthy rats.

In our recent studies we have designed fullerenol/doxorubicin nanocomposite (FNP/DOX) as the new drug nanocarrier. This research has demonstrated that this novel nanocomposite has had better implications on the liver tissue in vivo (Wistar rats treated intraperitoneally), than treatment based only on DOX. FNP/DOX has been characterised by DLS, TEM and AFM measurements which have shown that DOX loaded onto FNP did not influence fullerenol nanoparticle's size.

Antiaflatoxigenic effect of fullerene C nanoparticles at environmentally plausible concentrations.

Increased interest in fullerene C and derivatives in recent years implies an intensification of their environmental spread. Yet, the potential risks for living organisms are largely unknown, including the interaction of C with fungal organisms. This may be especially relevant for mycotoxigenic fungi since C may both scavenge and produce reactive oxygen species (ROS), and oxidative stress induces mycotoxin production in fungi.

Fullerol C(OH) nanoparticles and mycotoxigenic fungi: a preliminary investigation into modulation of mycotoxin production.

Increased use of fullerols in various fields and expected increase of their environmental spread impose the necessity for testing fullerol nanoparticles (FNP) effects on microbiota.
