“…6,7 Regarding the influence of magnetic fluids on the photosynthesis process, a small number of studies is dedicated, 4,[8][9][10] which revealed a stimulatory effect on the photo-assimilatory pigments content leading to stimulatory effects on the plants growth. This stimulatory effect may be explained on the basis of iron importance in the vegetal organisms.…”

The present experimental investigation is focused on the study of assimilatory pigments and nucleic acid levels in young plants intended for agricultural use (Zea mays) in presence of water based magnetic fluid added in culture medium. The magnetic fluid was constituted by coating the nanosized magnetic nanoparticles (with 10.55 nm average value of the physical diameter) with β-cyclodextrin (C 42 H 70 O 35 ) and further dispersion in water. After germination, various volume fractions (between 10 mL/L and 500 mL/L) of the magnetic fluid was added daily in the culture medium of Zea mays plants still at their early ontogenetic stages. Toxicity symptoms leaded to brown spots covering the leaf surface for the highest magnetic fluid volume fractions used, a putative oxidative stress generated by iron excess treatment. Relatively small volume fraction of magnetic fluid solutions induced the increase of chlorophyll a level (up to 38%), the main photosynthesis pigment, as well that the nucleic acid level (up to 57%) in Zea mays plantlets. All volume fractions of magnetic fluid solutions analyzed may have severe disruptive effects such as the ratio chlorophyll a/chlorophyll b (about 50% decreasing).

“…The study of antioxidant property gives an insight about the behavior and interaction of these materials with biomolecules inside a living system. Thus it is important to study the potency of metal oxide magnetic nanoparticles as antioxidants because of their recent uses and applications in biosystems [1][2][3][4][5]. But scanty reports are available on antioxidant property of these particles.…”

“…The microorganism growth in magnetic fluid in suspension was also studied by Dunca et al [3]. Experimental investigation by Racuciu and Creanga [4] focused on the study of the simultaneous influence of the water-based ferro-fluid and static magnetic field exposure on young cereal plants. Horak et al [5] isolated and identified the DNA in dairy products using magnetic particles.…”
