Plasma-enhanced synthesis and modification of polymers is a field that continues to expand and become increasingly more sophisticated. The highly reactive processing environments afforded by the inherently dynamic nature of plasma media are often superior to ambient or thermal environments, offering substantial advantages over other processing methods. The fluxes of energy and matter toward the surface enable rapid and efficient processing, whereas the charged nature of plasma-generated particles provides a means for their control. The range of materials that can be treated by plasmas is incredibly broad, spanning pure polymers, polymer-metal, polymer-wood, polymer-nanocarbon composites, and others. In this review, we briefly outline some of the recent examples of the state-of-the-art in the plasma-based polymer treatment and functionalization techniques.

This study aims at the establishment of a universally applicable etching methodology to unveil the nanoscale crystalline structure of the matrix resin in fiber reinforced thermoplastic (FRTP) composites scanning electron microscopy (SEM). The crystalline structure hierarchically consists of crystalline texture, spherulite and lamella. The details of these structures are key parameters to understand the relationship with the mechanical properties of the material for the advancement.

Platelet-Rich Fibrin (PRF) is an autologous matrix rich in platelets, leukocytes, and growth factors that support tissue regeneration. Enhancing its structural and biological properties through biomaterial supplementation may improve clinical outcomes. This study evaluated the effects of adding hyaluronic acid (HA) and collagen to PRF on growth factor release and mechanical strength.

Elucidating the earliest biological mechanisms underlying Alzheimer's disease (AD) is critical for advancing early detection strategies. While amyloid-β (Aβ) and tau pathologies have been central to preclinical AD research, the roles of peripheral biological processes in disease initiation remain underexplored. We investigated patterns of F-MK6240 tau positron emission tomography (PET) and peripheral inflammation across stages defined by Aβ burden and neuronal injury in n = 132 (64.

Polyethylene glycols (PEGs) are amphiphilic polymers that are used extensively in consumer products and PEGylated biotherapeutics. Although PEGs are considered biologically inert with a low toxicity, anti-PEG antibodies have been detected in patients receiving treatment with PEGylated biotherapeutics as well as in healthy individuals. Despite continual exposure in daily life, the prevalence of PEGs within the general population remains unclear.

The construction of perfluoropolyether (PFPE) slippery liquid-infused porous surfaces (SLIPS) on gold coatings is one of the most effective strategies for bestowing anticoagulation and antimicrobial properties on the material. However, the poor chemical affinity between fluorinated porous precursors and gold substrates causes the agglomeration of nanostructures, resulting in uneven nanoporous morphology and accelerating lubricant leakage. Simultaneously, the weak interfacial adhesion between the nanostructures and the substrate may lead to the detachment of nanostructures under blood circulation.
