“…Surfactant and co-surfactant are used to thermodynamically stabilise the mixture and form a clear and totally soluble solution. Water droplets are slowly dispersed and collided in the oil and surfactant solution forming a nano reactor which is driven by the Brownian motion [48,49]. Saha et al,(2011) have reported the removal of different dyes such as erichrome black-T, bromophenol blue and bromocresol green using iron oxide nanoparticles which are ferromagnetic in nature at both room and low temperature [50].Also, ZnFe2O4 spinel ferrite nanoparticles has been successfully used in the removal of Acid Red 88 dye from aqueous solution by adsorption [51].…”

Dyes are complex organic compounds which are used by various industries to colour their products. These dyes are purged from various industrial sources such as textile, cosmetic, paper, leather, rubber and printing industries. Wastewater effluents contain dyes which may cause potential hazards to the environment. Some of these dyes are toxic, carcinogenic and can cause skin and eye irritation. Therefore, many researchers have been studied the effectiveness of dyes removal from aqueous solution by different separation methods. Different separation techniques have been used for the treatment of dye-bearing wastewater such as adsorption, coagulation/flocculation, advanced oxidation technologies, ozonation, and membrane-filtration, aerobic and anaerobic degradation. All dye separation techniques have their own limitation in terms of design, operation efficiency and total cost. This review paper provides extensive literature information about dyes, its classification and toxicity together with various treatment methods into dye adsorption characteristics of several non-conventional cost effective sustainable adsorbents. The mechanism and the effects of various physio-chemical process parameters on dye adsorption are presented here.

“…In a more recent study, w/o microemulsion route was used to synthesize magnetite nanoparticles by using different kinds of surfactants to investigate the morphology, size, size distribution and crystalline feature of the resultant MNPs. [125] They used n-heptane as the oil phase, conventional single-chain surfactants and novel Gemini surfactants, and n-hexanol as the co-surfactant phase. Their results showed that nucleation and growth of the nanocrystalline are significantly affected by the film flexibility of the reverse micelles and life time of a surfactant molecule in the micelle.…”

“…The specific radioisotopes used account for the key difference between SPECT and PET imaging from a material point of view. 99m Tc, 111 In, 67 Ga, 125 I, 131 I, and 201 Ti are of the common radionuclides used for SPECT imaging in researches and biomedical applications. [788] Among these, 99m Tc has been extensively established due to being less expensive and more available than PET.…”

In order to translate nanotechnology into medical practice, magnetic nanoparticles (MNPs) have been presented as a class of non‐invasive nanomaterials for numerous biomedical applications. In particular, MNPs have opened a door for simultaneous diagnosis and brisk treatment of diseases in the form of theranostic agents. This review highlights the recent advances in preparation and utilization of MNPs from the synthesis and functionalization steps to the final design consideration in evading the body immune system for therapeutic and diagnostic applications with addressing the most recent examples of the literature in each section. This study provides a conceptual framework of a wide range of synthetic routes classified mainly as wet chemistry, state‐of‐the‐art microfluidic reactors, and biogenic routes, along with the most popular coating materials to stabilize resultant MNPs. Additionally, key aspects of prolonging the half‐life of MNPs via overcoming the sequential biological barriers are covered through unraveling the biophysical interactions at the bio–nano interface and giving a set of criteria to efficiently modulate MNPs' physicochemical properties. Furthermore, concepts of passive and active targeting for successful cell internalization, by respectively exploiting the unique properties of cancers and novel targeting ligands are described in detail. Finally, this study extensively covers the recent developments in magnetic drug targeting and hyperthermia as therapeutic applications of MNPs. In addition, multi‐modal imaging via fusion of magnetic resonance imaging, and also innovative magnetic particle imaging with other imaging techniques for early diagnosis of diseases are extensively provided.

Magnetic nanoparticles made from organic and inorganic materials have gained significant technological progress and are widely applied in biomedicine, including magnetic resonance imaging, targeted drug delivery systems, biosensors, hyperthermia, and tissue engineering. The most reported synthesis methods include hydrothermal, sol‐gel, laser ablation, microemulsion, and ball‐milling methods. The synthesis parameters have a strong correlation with essential properties, such as phase, size, and surface morphology, which greatly influence the macroscopic properties and potential applications of the particles. Different preparation methods result in magnetic nanoparticles with varying characteristics, and the appropriate method can be chosen based on the requirements of the specific application. Two effective methods for synthesizing magnetic nanoparticles are coprecipitation and hydrothermal method because the preparation is relatively simple with low energy consumption, and uniform and homogeneous crystals are obtained.
