The study of the interaction of TiSiO4 nanoparticles with the model system Allium cepa L.

Abstract

The present study aimed to investigate the effects of the interaction of titanium silicate nanoparticles (TiSiO4) with the meristematic cells of the Allium cepa roots, as an indicator system. TiSiO4 NPs with dimensions ≤50 nm, in the form of white powder, with a purity of 99.8% (based on trace metal analysis), purchased from Sigma-Aldrich, were used for the experiments. Onion bulbs were placed for germination in aqueous TiSiO4 NPs suspensions (dispersed by ultrasonic vibration (130 W, 20 kHz) for 30 min) of different concentrations (12.5 mg/l, 25 mg/l and 50 mg/l). Distilled water served as a control.
