“…Silica dispersion has a large phase interface, so the colloidal particles are in an unstable state to be destroyed and agglomerated. , Consequently, the one-step synthesis and hydrophobic modification have been adopted to improve stability for fabricating the modified silica dispersion with excellent dispersibility. During the process of one-step synthesis of the modified silica dispersion, dodecyltrimethoxysilane was used to modify the surface of dispersed phase particles (silica), reduce the surface energy, and play a role in steric hindrance on the surface of silica. − Zeta potential (absolute value) is usually an important index to evaluate the stability of the colloidal dispersion system. , The silica dispersion with 437.2 ± 13.1 nm average particle size and the modified silica dispersion with 462.25 ± 4.65 nm average particle size were synthesized, it was found that the modified silica dispersion had a large zeta potential (0.1 g/L, 32.8 ± 0.9 mV), and its stability was better than that of the silica dispersion by comparing with the zeta potential of the silica dispersion (0.1 g/L, 17.45 ± 0.95 mV).…”

Water-based superamphiphobic coatings are environmentfriendly, which have attracted tremendous attention recently, but the performances are severely limited by the dispersibility of hydrophobic particles. To solve the poor dispersibility of modified silica powder with hydrophobicity, silica dispersion was blended with polytetrafluoroethylene (PTFE) emulsion and modified aluminum tripolyphosphate (ATP) dispersion to successfully prepare water-based coatings. Multifunctional coatings were prepared by one-step spraying. It possessed good adhesion (grade 1), excellent antifouling, impact resistance, chemical stability (acid and alkali resistance for 96 h of immersion), and corrosion resistance (3.5 wt % NaCl solutions for 20 days). More importantly, the superamphiphobic coatings had high contact angles (CAs) and low slide angles (SAs) for ethylene glycol (CAs = 154 ± 0.8°; SAs = 13 ± 0.7°) and water (CAs = 158 ± 0.7°; SAs = 4 ± 0.3°). Furthermore, the composite coating was still hydrophobic after 35 cycles of wear with high roughness sandpaper (120 mesh) under three different loads, which maintained superamphiphobicity at 425 °C. This work is expected to provide a facile idea and method for the preparation of waterborne superamphiphobic coatings.

“…The degree and nature of the interaction between particles can be accessed by the zeta potential (ZP) value. Zeta or electrokinetic potential represents the potential at the shear plane, which directly impacts the stability of the drug product [ 165 ]. Usually, a system with a higher ZP value (positive or negative) is electrically stable, but a low ZP value leads to instability [ 166 ].…”

There has been a constant evolution in the pharmaceutical market concerning the new technologies imbibed in delivering drug substances for various indications. This is either market-driven or technology-driven to improve the overall therapeutic efficacy and patients’ quality of life. The pharmaceutical industry has experienced rapid growth in the area of complex injectable products because of their effectiveness in the unmet market. These novel parenteral products, viz, the nanoparticles, liposomes, microspheres, suspensions, and emulsions, have proven their worth as “Safe and Effective” products. However, the underlying challenges involved in the development, scalability, and characterization of these injectable products are critical. Moreover, the guidelines available do not provide a clear understanding of these complex products, making it difficult to anticipate the regulatory requirements. Thus, it becomes imperative to comprehend the criticalities and develop an understanding of these products. This review discusses various complexities involved in the parenteral products such as complex drug substances, excipients, dosage forms, drug administration devices like pre-filled syringes and injector pens, and its different characterization tools and techniques. The review also provides a brief discussion on the regulatory aspects and associated hurdles with other parenteral products. Graphical abstract
