Iron is a micronutrient essential for optimal plant development, nevertheless, due to their low solubility it is poorly available to plants, affecting many agronomically important crops. Nanofertilizers are nanoparticles that have been used as an alt

Poly(acrylic acid)-Coated Iron Oxide Nanoparticles (PAC-IONs) did not compromise the viability of mononuclear cells and potentially interact with cells through scavenger receptors. This study evaluated: 1) The capacity of the PAC-IONs to induce plate
