Article Abstract
Self-assembly of thrombin-free solutions of fibrinogen can be triggered not only by a drop in the ionic strength but also by an appropriate decrease in temperature. Accordingly, an in situ study of self-assembly of fibrinogen in saline buffered solution is carried out by means of time-resolved light scattering providing the molar mass, geometric size, and hydrodynamic radius of the growing intermediates. The resulting data provide access to the morphology of the intermediates and to the mechanism in which these intermediates grow during the early stages of self-assembly. Modeling the results of concentration dependent experiments based on temperature gradients in terms of a chain growth mechanism leads to the corresponding molar standard enthalpy and entropy of aggregation.

Lubrication surfaces reduce the risk of cross-contamination and enhance the long-term stability of medical devices, which holds significance in the realm of antifouling medical materials. However, the complexity of constructing micronano structures to immobilize lubricating fluids and the fluorine content typically found in silane coupling agents restrict their widespread adoption. In this study, we prepared a biomimetic lubricating coating (BLC) through the one-step self-assembly of octadecyltrichlorosilane and oil infusion.

Despite significant progress in skin wound healing, it is still a challenge to construct multifunctional bioactive dressings based on a highly aligned protein fiber coated hydrogel matrix for antifibrosis skin wound regeneration that is indistinguishable to native skin. In this study, a "dual-wheel-driven" strategy is adopted to modify the surface of methacrylated gelatin (GelMA) hydrogel with highly aligned magnetic nanocomposites-protein fiber assemblies (MPF) consisting of photothermal responsive antibacteria superparamagnetic nanocomposites-fibrinogen (Fg) complexes as the building blocks. Whole-phase healing properties of the modified hydrogel dressing, GelMA-MPF (GMPF), stem from the integration of Fg protein with RGD peptide activity decorated on the surface of the antibacterial magnetic nanoactuator, facilitating facile and reproducible dressing preparation by self-assembly and involving biochemical, morphological, and biophysical cues.

Recent clinical studies have highlighted the presence of microclots in the form of amyloid fibrinogen particles (AFPs) in plasma samples from Long COVID patients. However, the clinical significance of these abnormal, nonfibrillar self-assembly aggregates of human fibrinogen remains debated due to the limited understanding of their structural and biological characteristics. In this study, we present a method for generating mimetic microclots in vitro.

Article Synopsis
- * The study examined how factors like scaffold layering, cross-linking time, and freeze-drying impact the stability and properties of these nanofibers, finding that cross-linking with formaldehyde vapor offers optimal stability.
- * Results show that different cross-linking times alter mechanical properties without changing hydration, and the nanofibers have a higher susceptibility to enzyme degradation compared to planar forms, highlighting their potential in soft tissue applications.
