“…This facilitates, for instance, one-step and one-pot strategies where just one system is possible to conduct multiple reactions. This approach is economically attractive as it considerably reduces the number of processing steps and consequently, the investment in equipment and involved personnel [69,79]. One major challenge is to assure the high immobilization efficiencies of active molecules.…”

The oil and gas industry generates large amounts of oil-derived effluents such as Heavy Crude Oil (HCO) in water (W) emulsions, which pose a significant remediation and recovery challenge due to their high stability and the presence of environmentally concerning compounds. Nanomaterials emerge as a suitable alternative for the recovery of such effluents, as they can separate them under mild conditions. Additionally, different biomolecules with bioremediation and interfacial capabilities have been explored to functionalize such nanomaterials to improve their performance even further. Here, we put forward the notion of combining these technologies for the simultaneous separation and treatment of O/W effluent emulsions by a novel co-immobilization approach where both OmpA (a biosurfactant) and Laccase (a remediation enzyme) were effectively immobilized on polyether amine (PEA)-modified magnetite nanoparticles (MNPs). The obtained bionanocompounds (i.e., MNP-PEA-OmpA, MNP-PEA-Laccase, and MNP-PEA-OmpA-Laccase) were successfully characterized via DLS, XRD, TEM, TGA, and FTIR. The demulsification of O/W emulsions was achieved by MNP-PEA-OmpA and MNP-PEA-OmpA-Laccase at 5000 ppm. This effect was further improved by applying an external magnetic field to approach HCO removal efficiencies of 81% and 88%, respectively. The degradation efficiencies with these two bionanocompounds reached levels of between 5% and 50% for the present compounds. Taken together, our results indicate that the developed nanoplatform holds significant promise for the efficient treatment of emulsified effluents from the oil and gas industry.

“…Some heavy metals like Zn and Cu are considered micro-nutrients but they may become poisonous for aquatic life and humans at high concentration. Jain and team reported biogenic Se-NPs by mixing and incubating Se with cultured anaerobic sludge for minimizing Zn (II) in samples of wastewater (Jain et al, 2015).A team led by Kandasamy, synthesized biogenic Fe-NPs from Streptomyces thermolineatus for the elimination of Cu ions from the effluents of the pigment industry (Kandasamy, 2017). A group of researchers engineered Se-NPs from bacterial extracellular polymeric substances (EPS) for removing elemental Hg from groundwater (Wang et al, 2018).…”

Nanoscience is a rapidly growing science stream that has been one of the cost-effective and energy-efficient approaches with wide applications. Water pollution is a major issue that is increasing continuously due to anthropogenic activities and several organic and inorganic contaminants. To overcome this issue, nanoparticles (NPs) have been successfully used to treat water. These NPs possess many beneficial applications in many fields like agriculture, cosmetics, photoconductors, environmental biotechnology, glass and alloy production, solar cells, nanomedicine and drug deliveries, biosensors, food industries, etc. The properties comprising high surface area, greater chemical reactivity, and mechanical properties play a vital role in imparting such beneficiary properties. As a result, there has been an increasing demand for the synthesis of NPs. However, excess usage of NPs further creates toxic by-products. Therefore, scientists and researchers are now focussing on the biogenic synthesis of NPs. The biological routes of NP synthesis have been crucial because they are eco-friendly and environmentally safe. This chapter highlights the usage of different approaches and biogenic sources for the production of NPs. It also discusses the recent advancement in the use of biogenic NPs with respect to applications for wastewater treatment.

“…Excellent quality iron oxide magnetic nanoparticle can be synthesized by adopting versatile synthetic approaches include thermal decomposition, co-precipitation, micelle formation, hydrothermal and laser pyrolysis techniques. It was difficult for us to compile all this literature and we have attempted to present each synthetic approach by giving a few examples along with the corresponding formation mechanism (Ali et al, 2016;Martínez-Cabanas et al, 2016;Elrouby et al, 2017;Kandasamy, 2017;Lin et al, 2017;Liu et al, 2017;Rajiv et al, 2017;Sathya et al, 2017).…”

“…For application in pharmaceutical and biomedical purposes, iron oxide magnetic nanoparticles should possess smaller size (50-160 nm) and high magnetization values (Mohammed et al, 2017). Surface coatings are meant to ensure stability and biocompatibility for specific localization at the target site ( Figure 2) (Kandasamy, 2017).…”

Substances at nanoscale, commonly known as "nanomaterials," have always grabbed the attention of researchers for hundreds of years. Among these different types of nanomaterials, magnetic nanomaterials have been the focus of considerable attention during the last two decades as evidenced by an unprecedented increase in the number of research papers focusing these materials. Iron oxide magnetic nanoparticles have occupied a vital position in imaging phenomena; as drug vehicles, controlled/sustained release phenomena and hyperthermia; atherosclerosis diagnosis; prostate cancer. In fact, these are wonderful "theranostic" agents with some under clinical trials for human use. In this review, we have attempted to highlight the advances taking place in the field of magnetic nanoparticles as theranostic agents. Extensive progress has been made in the two most important parameters, namely, control over the size and shape which decide the importance of iron oxide magnetic nanoparticles by developing suitable procedures like precipitation, co-precipitation, thermal decomposition, hydrothermal synthesis, microemulsion synthesis and plant mediated synthesis. After using a suitable synthetic route, workers encounter the most daunting task linked with the materials at nanoscale i.e., the protection against corrosion. Only properly protected iron oxide magnetic nanoparticles can be further connected to different functional systems to make building blocks for application in catalysis, biology and medicines. Finally, "theranostics" which is a combined application of imaging and drug delivery has been discussed. With all the potential uses, toxicity of the of iron oxide magnetic nanoparticles has been discussed.
