Abstract: Introduction. Single-walled carbon nanotubes(SWCNT) represents a promising material for the biomedical field. However, reports have appeared that suggest that toxic effects can appear following SWCNT exposure. Aim. Present study aims to evaluate the in vitro effects following exposure to low dose of single walled carbon nanotubes functionalized with single strand DNA (SWCNT-ss-DNA) over HeLa cells. Material and Method. Synthesis of the SWCNT (inductive heating method, acetylene, 850oC, Fe:Mo:MgO catalyst), followed by non-covalent binding of single strand DNA(ss-DNA) through sonication. HeLa cell line was exposed to 1mg/L ss-DNA-SWCNT solution with monitoring at 15 min, 24 hrs, 48 hrs. Results. No toxic effects were observed at microscopic evaluation of cell morphology and at quantitative viability evaluation by means of MTT assay.(p>0.05). Conclusions. Limited dose exposure of HeLa cells to SWCNT-ss-DNA induces no cytotoxic effects.
