“…2). The isoelectric point (pH iep ) of TiO 2 NPs in UHPW corresponds to pH 7.12, which is in good agreement with those pH iep reported in other studies with pH values varying from 6.7 to 7.5 (Fernández-Nieves et al, 1998;Finnegan et al, 2007;Larue et al, 2011). The hydrodynamic diameter of the NPs has increased drastically with increasing pH to about 7.0 (Fig.…”

“…In the cytoplasm, nanoparticles approach to different cytoplasmic organelles and interfere with different metabolic processes of the cell (Moore 2006). Furthermore, Larue et al (2011) studied the uptake of TiO 2 nanoparticles in wheat and observed the nanoparticles in parenchyma and vascular tissues of the root. Lin and Xing (2008) examined the cell internalization and upward translocation of ZnO nanoparticles in Lolium perenne (ryegrass).…”

Outburst of world population in the past decade has forced the agricultural sector to increase crop productivity to satisfy the needs of billions of people especially in developing countries. Widespread existence of nutrient deficiency in soils has resulted in great economic loss for farmers and significant decreases in nutritional quality and overall quantity of grains for human beings and livestock. Use of large-scale application of chemical fertilizers to increase the crop productivity is not a suitable option for long run because the chemical fertilizers are considered as double-edged swords, which on the one hand increase the crop production but on the other hand disturb the soil mineral balance and decrease soil fertility. Large-scale application of chemical fertilizers results in an irreparable damage to the soil structure, mineral cycles, soil microbial flora, plants, and even more on the food chains across ecosystems leading to heritable mutations in future generations of consumers.In recent years, nanotechnology has extended its relevance in plant science and agriculture. Advancement in nanotechnology has improved ways for large-scale production of nanoparticles of physiologically important metals, which are now used to improve fertilizer formulations for increased uptake in plant cells and by minimizing nutrient loss. Nanoparticles have high surface area, sorption capacity, and controlled-release kinetics to targeted sites making them "smart delivery system." Nanostructured fertilizers can increase the nutrient use efficiency through mechanisms such as targeted delivery, slow or controlled release. They could precisely release their active ingredients in responding to environmental triggers and biological demands. In recent lab scale investigations, it has been reported that nano-fertilizers can improve crop productivity by enhancing the rate of seed germination, seedling growth, photosynthetic activity, nitrogen metabolism, and carbohydrate and protein synthesis. However, as being an infant technology, the ethical and safety issues surrounding the use of nanoparticles in plant productivity are limitless and must be very carefully evaluated before adapting the use of the so-called nano-fertilizers in agricultural fields.

The successful development of nanomaterials illustrates the considerable interest in the development of new molecular probes for medical diagnosis and imaging. Substantial progress was made in synthesis protocol and characterization of these materials whereas toxicological issues are sometimes incomplete. Nanoparticle-based contrast agents tend to become efficient tools for enhancing medical diagnostics and surgery for a wide range of 2 imaging modalities. Multimodal nanoparticles (NPs) are much more efficient than conventional molecular-scale contrast agents. They provide new abilities for in vivo detection and enhanced targeting efficiencies through longer circulation times, designed clearance pathways, and multiple binding capacities. Properly protected, they can safely be used for the fabrication of various functional systems with targeting properties, reduced toxicity and proper removal from the body. This review mainly describes the advances in the development of mono-to multimodal NPs and their in vitro and in vivo relevant biomedical applications ranging from imaging and tracking to cancer treatment. Besides specific applications for classical imaging, (MRI, PET, CT, US, PAI) are also mentioned less common imaging techniques such as terahertz molecular imaging (THMI) or ion beam analysis (IBA).Perspectives on multimodal theranostic NPs and their potential for clinical advances are also mentioned.
