“…One is milling without surfactants, called dry milling, and the other is milling with surfactants, called wet milling. A surfactant, such as heptane, oleic acid, etc, is adsorbed on the new surfaces of particles peeled off from the bulk material during the milling process [126][127][128]. Then, the fresh surfaces of the new particles are separated by layers of surfactant, which can help decrease the welding effect of small particles to obtain nanoparticles with smaller sizes.…”

Magnetic nanoparticles (MNPs) have unique physical and chemical properties, such as high surface area to volume ratio and size-related magnetism, which are completely different from their bulk materials. Benefiting from the facile synthesis and chemical modification strategies, MNPs have been widely studied for applications in nanomedicine. Herein, we firstly summarized the designs of MNPs from the perspectives of materials and physicochemical properties tailored for biomedical applications. Magnetic particle spectroscopy (MPS), first reported in 2006, has flourished as an independent platform for many biological and biomedical applications. It has been extensively reported as a versatile platform for a variety of bioassays along with the artificially designed MNPs, where the MNPs serve as magnetic nanoprobes to specifically probe target analytes from fluid samples. In this review, the mechanisms and theories of different MPS platforms realizing volumetric- and surface-based bioassays are discussed. Some representative works of MPS platforms for applications such as disease diagnosis, food safety and plant pathology monitoring, drug screening, thrombus maturity assessments are reviewed. At the end of this review, we commented on the rapid growth and booming of MPS-based bioassays in its first 15 years. We also prospected opportunities and challenges that portable MPS devices face in the rapidly growing demand for fast, inexpensive, and easy-to-use biometric techniques.

It is highly desirable to develop bio‐based products using sustainable materials and reduce dependence on petrochemicals. There are various reports on the use of sustainable materials in the synthesis of polymer resins, but research on the use of sustainable materials in development of coating additives such as polymeric dispersant is significantly lacking. Objective of this work is to produce fatty acid‐based polymeric dispersant using oleic acid in combination with butyl acrylate. The performance of the fatty acid‐based polymeric dispersant was benchmarked against commercially available and petrochemical‐based polymeric dispersant. The dispersants produced were characterized using spectroscopies (1H‐NMR and FTIR), thermal analyses (thermogravimetric analysis and differential scanning calorimetry), and molecular weight analysis. Application test was conducted to evaluate the effectiveness of the polymeric dispersant in titania pigment concentrate formulation which was tinted in nitrocellulose clear coating. Properties such as viscosity, fineness, gloss, optical properties, and storage stability were evaluated, and the result obtained shows that fatty acid‐based polymeric dispersant could disperse titania efficiently and produced coatings with good optical properties and excellent gloss retention. The carboxyl group from the incorporated fatty acid served as excellent pigment anchoring group, facilitating good orientation of dispersant on the pigment surface and promote excellent stability.
