“…In order to proof and tune the performance of the microdevice, the quantitative description of the interaction of Fe2O3@SiO2 COOH NPs with polymyxin B is necessary. Interestingly, the results can be also used in the case of application of these NPs for the treatment of wastewaters contaminated by antibiotics [44,45].…”

In this work, interactions of carboxylated core shell magnetic nanoparticles with polymyxin B sulfate were studied by connecting capillary electrophoresis with inductively coupled plasma mass spectrometry. The interaction was probed by affinity mode of capillary electrophoresis with 25 mM phosphate buffer at physiological pH. 54 Fe, 56 Fe, 57 Fe, 34 S, and 12 C isotopes were used to monitor the migration of an electroosmotic flow marker and the interaction of the nanoparticles with polymyxin B. The analysis of interaction data showed two distinct interaction regions, one with low polymyxin B concentration, the second with high polymyxin B concentration. These regions differed in the strength of the interaction, 14.9 x 10 6 M-1 and 16.0 x 10 3 M-1 , and in the stoichiometry of 0.7 and 3.5, respectively. These differences can be explained by the decrease of electrostatic repulsion between nanoparticles caused by polymyxin B. This is also in agreement with the nanoparticles peak shapes: sharp for low polymyxin B concentrations and broad for high polymyxin B concentrations.

“…Therefore, considerable effort has been made in recent years to identify an optimal treatment method to remove antibiotics from wastewater. Thus, the possibility of removing the antibiotics through adsorption [5,6], advanced oxidation [7,8], and biological processes has been intensively studied [9][10][11]. Of all these methods, photocatalytic oxidation, and especially heterogeneous photocatalysis with TiO 2 , has received particular attention due to the advantages that this method offers [12].…”

New photocatalytic membranes based on polylactic acid (PLA)/TiO2 hybrid nanofibers deposited on fiberglass supports were prepared and tested for the removal of ampicillin from aqueous solutions. The electrospinning technique was used to obtain hybrid nanofibers that were deposited on three types of fiberglass with different structures, resulting in three distinct photocatalytic membranes namely fiberglass fabric plain woven-type membrane, fiberglass mat-type membrane, and fiberglass fabric one-fold edge-type membrane. The results of the photocatalytic tests showed that the highest efficiency of ampicillin removal from aqueous solution is obtained with the fiberglass fabric plain woven-type membrane. Although it has been shown that the rate of photocatalytic degradation of ampicillin is high, being practically eliminated within the first 30 min of photocatalysis, the degree of mineralization of the aqueous solution is low even after two hours of photocatalysis due to the degradation of PLA from the photocatalytic membrane. The instability of PLA in the reactive environment of the photocatalytic reactor, evidenced by morphological, mineralogical and spectroscopic analyzes as well as by kinetic studies, is closely related to the structure of the fiberglass membrane used as a support for PLA/TiO2 hybrid nanofibers.

“…Their high specific surface area and diversity with respect to surface functionalization provide unique physicochemical properties to these materials, rendering them highly effective in water remediation processes. Functionalized magnetic nanoparticles (MNPs) have been employed as adsorbents for the removal of toxic metal ions, pesticides and antibiotics from wastewater and agricultural wastewater [9] (Figure 2). In addition to their high surface area and the functionalization of their surface with appropriate adsorption moieties enabling the removal of contaminants via the development of electrostatic interactions, π-stacking and cation-π-interactions, hydrogen bonding, metal ion complexation, etc., their inherent magnetic properties provide an additional advantage, being the facile separation of the adsorbent and recovery from aqueous solutions upon completion of the adsorption process by means of an externally applied magnetic field.…”

The development of functional nanomaterials exhibiting cost-effectiveness, biocompatibility and biodegradability in the form of nanoadditives, nanofertilizers, nanosensors, nanopesticides and herbicides, etc., has attracted considerable attention in the field of agriculture. Such nanomaterials have demonstrated the ability to increase crop production, enable the efficient and targeted delivery of agrochemicals and nutrients, enhance plant resistance to various stress factors and act as nanosensors for the detection of various pollutants, plant diseases and insufficient plant nutrition. Among others, functional magnetic nanomaterials based on iron, iron oxide, cobalt, cobalt and nickel ferrite nanoparticles, etc., are currently being investigated in agricultural applications due to their unique and tunable magnetic properties, the existing versatility with regard to their (bio)functionalization, and in some cases, their inherent ability to increase crop yield. This review article provides an up-to-date appraisal of functionalized magnetic nanomaterials being explored in the agricultural sector.
