Fluidic channels were employed to induce the self-assembly of poly(ethylene glycol)-b-polystyrene into polymeric vesicles and nanotubes. The laminar flow in the device enables controlled diffusion of two miscible liquids at the phase boundary, leading to the formation of homogeneous polymeric structures of different shapes. These structures could be easily loaded with small molecule cargoes and functionalized with nanometer sized catalytic platinum nanoparticles. This technique offers a facile methodology to rapidly and continuously produce well-defined polymeric structures for nanotechnology applications.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is an increasingly prevalent chronic liver condition that can progress to severe complications such as metabolic dysfunction-associated steatohepatitis (MASH). Despite its growing burden, there are no reliable non-invasive biomarkers for tracking disease progression. In this study, we established a murine MASLD/MASH model using a high-fat diet and chemical (CCl) induction.

Photodegradable nanoparticles with sphere, worm, and vesicle morphologies were synthesized following polymerization induced self-assembly (PISA), incorporating a photoresponsive phenyl vinyl ketone (PVK) block and a nonphoto responsive 2-hydroxypropyl methacrylamide (HPMA) block. The photodegradation of nanoparticles under UV revealed that the initial shapes of sphere and vesicle particles are retained even until 7 h and after 24 h of photo-induced degradation, respectively, despite a significant reduction in molecular weight (M). This could be due to the assembly of degraded PVK fragments in the hydrophobic region, maintaining the relative hydrophilic to hydrophobic ratio.

The primary objective of this study was to develop a nanosuspension based on orthoester compounds (OE) and carboxymethyl chitosan (CMCS) for the combined treatment of tumors. Initially, OE was synthesized as a liquid pharmaceutical excipient. Subsequently, nanoparticles were formulated using CMCS and loaded with mitoxantrone (MIT).

Intervertebral disc degeneration (IVDD) is a common age-related disorder associated with inflammation, pain and impaired mobility. In this study, we developed a therapeutic system using silk fibroin (SF) hydrogel loaded with mRNA-engineered extracellular vesicles derived from murine bone marrow mesenchymal stem cells (BMSCs-EVs) to modulate macrophage polarization and alleviate IVDD. BMSCs were isolated from 6-week-old C57BL/6 mice, and an acute IVDD model was established via 18G needle puncture of the coccygeal discs (Co7-Co10).

Osteoarthritis (OA) is a degenerative joint disease closely associated with aging for which current treatments are limited primarily to symptomatic relief and fail to reverse pathological progression. A growing body of evidence indicates that the accumulation of senescent cells is a central driver of OA pathogenesis. This review systematically summarizes the latest advancements in antisenescence biomaterials for OA therapy, emphasizing their potential to overcome the limitations of conventional approaches by improving drug targeting, prolonging drug release kinetics, and increasing bioavailability.
