Ethylhexyl methoxycinnamate (EHMC) is frequently employed as a photoprotective agent in sunscreen formulations. EHMC has been found to potentially contribute to health complications as a result of its propensity to produce irritation and permeate the skin. A microgel carrier, consisting of poly(ethylene glycol dimethacrylate) (pEDGMA), was synthesized using interfacial polymerization with the aim of reducing the irritation and penetration of EHMC. The thermogravimetric analysis (TGA) indicated that the EHMC content accounted for 75.72% of the total composition. Additionally, the scanning electron microscopy (SEM) images depicted the microgel as exhibiting a spherical morphology. In this study, the loading of EHMC was demonstrated through FTIR and contact angle tests. The UV resistance, penetration, and skin irritation of the EHMC-pEDGMA microgel were additionally assessed. The investigation revealed that the novel sunscreen compound, characterized by limited dermal absorption, had no irritant effects and offered sufficient protection against ultraviolet radiation.

Elucidating the role of carrier proteins in cytokine stabilization within double emulsion-based polymeric nanoparticles.

January 2025
Polymeric micro- and nanoparticles are useful vehicles for delivering cytokines to diseased tissues such as solid tumors. Double emulsion solvent evaporation is one of the most common techniques to formulate cytokines into vehicles made from hydrophobic polymers; however, the liquid-liquid interfaces formed during emulsification can greatly affect the stability and therapeutic performance of encapsulated cytokines. To develop more effective cytokine-delivery systems, a clear molecular understanding of the interactions between relevant proteins and solvents used in the preparation of such particles is needed.

A finite element model of the local mechanical response of a filled polymer composite to uniaxial compression is presented. The interfacial layer between filler particles and polymer matrix is explicitly modeled as a third phase of the composite. Unit cells containing one or several anisometric filler particles surrounded by interface shells are considered.

Polydimethylsiloxane (PDMS) is extensively employed in applications ranging from flexible electronics to microfluidics due to its elasticity, transparency, and biocompatibility. However, enhancing interfacial adhesion and tensile properties remains a challenge for applications demanding high mechanical stability. To this end, this study introduced a novel bonding technique using crosslinkers as adhesive layers to improve the mechanical performance of PDMS.
