Summary: Hydrogels of poly(vinyl alcohol) (PVA)/sodium alginate (SA) with randomly distributed magnetic nanoparticles (MNPs) and magnetically oriented MNPs were prepared. Atomic force microscopy (AFM) and magnetic force microscopy (MFM) were used to evaluate the topography and magnetic domains distribution. The results showed that the orientation of magnetic domains led to an increase of surface roughness, which decreased the viability of HT-22 cells. These findings are important for situations where control of cell proliferation is necessary.

Summary: Food gels are attractive for their biocompatibility, eco-friendly characteristics, and wide range of medical and food applications. This study examined the use of phycocyanin and honey embedded in a gel-type delivery system composed of alginate and gelatin. The results showed that higher alginate concentration increased the release of phenolic content, and the gel structure protected the phenolic content during digestion and enhanced their bio-accessibility. The study suggests that a combination of 1.5 g/100 mL alginate with gelatin can improve the functionality and bio-accessibility of functional ingredients without affecting sensory properties.

Summary: The study encapsulated triptorelin acetate into silica microparticles and combined them with silica nanoparticles to form an injectable silica-triptorelin acetate depot. In vivo pharmacokinetics showed that the depot had lower Cmax values compared to Pamorelin(R) injections, but had sustained drug release and comparable pharmacodynamic effects. Plasma concentrations of triptorelin remained detectable in the depot even after 91 days, while testosterone levels stayed below the human castration limit for the same period.

Summary: This study presents a new SERS and SEF platform approach using substrates composed of alginate-stabilized silver nanoparticles encapsulated in calcium alginate hydrogel beads. The distance between probe molecules and metallic nanoparticles, determined by electrostatic repulsion or attraction between charged dyes and carboxylate groups of alginate, defines the SERS or SEF effect. The results demonstrate the detection of SEF effect with IR-820 dye in the near-infrared and visible regions, as well as the SERRS effect and fluorescence quenching with cationic dye in the same AgALGbeads substrate.

Summary: The investigation of regulated cell death (RCD) has gained increasing importance in recent years. A microfluidics-based technique called shear flow deformability cytometry (sDC) is used to distinguish dying cells from viable cells based on their mechanical properties. Analysis of the deformation and morphological characteristics of cells indicates significant differences in RCD-induced cells compared to control cells. These results highlight the importance of mechanical properties during RCD and the significance of label-free techniques like sDC for the detection and sorting of live and dead cells.

Summary: The clearance of dead cells is important for tissue homeostasis and immune responses, but the impact of the mechanobiological properties of dead cells on efferocytosis is not well understood. This study found that cancer cells undergoing ferroptosis have reduced Young's modulus. A nano-coating was developed to modulate their Young's modulus. The coating increased the Young's modulus of the dead cells and enhanced their efferocytosis by macrophages. This research highlights the crucial role of mechanobiology in regulating efferocytosis and its potential for therapeutic strategies and drug delivery systems.

Summary: The paradigm of drug delivery via particulate formulations enables overcoming limitations of traditional chemotherapeutic agents. Stimuli-responsive systems capable of controlled cargo release are widely accepted, with endogenous pH being the most common trigger. However, challenges such as accumulation in off-target tissues, immunogenicity, and complexity of drug delivery hinder the implementation of this idea. This article discusses fundamental strategies for pH-responsive drug delivery, limitations, main problems, weaknesses, and reasons for poor clinical results.

Summary: Transcutaneous immunization is a promising non-invasive approach for delivering vaccines to antigen presenting cells in the skin. In this study, a novel protocol for transfollicular immunization using porous calcium carbonate carriers and sonophoresis was developed to deliver an inactivated influenza vaccine to perifollicular cells without disrupting the skin's barrier. In vivo monitoring demonstrated the successful transport of vaccine-loaded particles into hair follicles, and the effectiveness of the protocol was confirmed in an animal model through immune response assays. This study highlights the potential of intra-follicular delivery of vaccines as a less invasive alternative to traditional immunization methods.

Summary: Cardiovascular diseases are the leading cause of death worldwide. Poly(alkylene terephthalate)s (PATs) with longer alkyl chain lengths show potential for improving compliance in vascular graft materials. This study investigated the effects of polymer molar mass and alkyl chain length on the surface properties of spin-coated PAT films, as well as endothelial cell adhesion and proliferation. The results showed that higher molar mass and longer alkyl chain lengths increased surface roughness, while no significant trend was observed for wettability. All investigated PATs were non-cytotoxic and supported endothelial cell adhesion and growth, with some PATs even promoting angiogenic maturation.
