Summary: In this study, the hydrophilicity and biocompatibility of surfaces modified with 2-methacryloyloxyethyl phosphorylcholine (MPC) were evaluated under different pH conditions. The MPC-modified surfaces exhibited high hydrophilicity at neutral pH due to ionization, but the hydrophilicity decreased under acidic conditions due to the decrease in negative charge. The biocompatibility was evaluated by measuring the prevention of fibrinogen adsorption, which was significantly lower on the MPC-modified surface at pH 7.6 compared to the bare glass, but increased at pH 2.8 indicating decreased biocompatibility.

Summary: In this study, a long-lasting antibacterial nanofibrous mat was fabricated by integrating zwitterionic materials and antibacterial photodynamic therapy (aPDT) photosensitizer. The nanofibrous mat showed good water absorption and retention ability, excellent cytocompatibility, and antibiofouling ability. Under moderate irradiation, the mat exhibited superior aPDT against Gram-positive bacteria and had a long-lasting drug release profile that efficiently suppressed bacterial growth. Its antibacterial ability was comparable to antibiotics, suggesting its potential as an antibiotic alternative.

Summary: In this study, a successful construction of zwitterionic copolymers (poly (sulfobetaine methacrylate-co-butyl acrylate) (pSB) coating on the surface of a hydroxylated titanium sheet using surface-initiated atom transfer radical polymerization (SI-ATRP) was achieved. The successful preparation of the coating was confirmed by X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FT-IR), and water contact angle (WCA) analysis. The swelling effect caused by the antipolyelectrolyte effect was observed in vitro, and the coating promoted the proliferation and osteogenesis of MC3T3-E1. Therefore, this study provides a new strategy for designing multifunctional biomaterials for implant surface modifications.

Summary: Flexible capacitive sensors based on silicone rubber are important in both academic and industrial fields due to their advantages, but they require dielectric additives to enhance electrical properties, which also increase Young's modulus. Liquid silicone rubbers are commonly used in academia, but compromise mechanical integrity, while high-consistency silicone rubbers maintain mechanical integrity but have limited use in dielectrics. This paper explores the potential of vinyl-terminated HCR for developing dielectric composites with high electromechanical response while retaining mechanical and processability properties.

Summary: In this study, a simple strategy was developed to construct reusable and highly efficient bilirubin adsorbents for hemoperfusion application. The strategy involved incorporating zwitterionic modules into a porous organic polymer (POP) to improve its hemocompatibility, hydrophilicity, and bilirubin uptake. Among the tested zwitterions, POP-CB-40% showed the best bilirubin uptake, with a 46.5 times enhancement compared to the non-zwitterionic POP in 100% serum. Furthermore, it was found that POP-CB-40% maintained around 99% of its bilirubin uptake capacity after five cycles in 100% serum, indicating its reusability. These findings provide a helpful guideline for designing biocompatible and efficient POP-based bilirubin adsorbents for hemoperfusion therapy.

Summary: This study presents an approach to repurposable and readily degradable silicone elastomers using alpha-lipoic acid. The resulting thermoplastic elastomers have properties that remain essentially unchanged after multiple heating cycles. Reduction of the disulfide linkages transforms the elastomers into oils, which can crosslink under air to give new elastomers with slightly higher mechanical properties. This process leads to elastomers that are more sustainable and facilitate reuse, repurposing, and recycling.

Summary: Increased consumption of high-fat low-fiber foods is associated with the development of metabolic syndromes. Fermentable dietary fiber, such as inulin, can alleviate metabolic abnormalities. This study systematically investigated the effect of inulin on mice with metabolic disorders induced by short-term and long-term high-fat feeding. The results showed that inulin reduced body weight, improved glucose intolerance, and alleviated hepatic steatosis in both groups of mice, suggesting a potential mechanism mediated through the modulation of gut microbiota.

Summary: Most bioadhesives are ineffective on bleeding tissues and postoperative adhesion is a common issue. A three-layer biodegradable Janus tissue patch (J-TP) is developed to efficiently close bleeding wounds, promote clotting, and prevent tissue adhesion. The J-TP's adhesive hydrogel bottom layer forms strong adhesion to bleeding tissues through chemical bonding, while the middle layer improves tensile strength and the top layer prevents postoperative adhesion and inflammation. This J-TP shows promise in the clinical treatment of injured bleeding tissues with inhibited adhesion.

Summary: Good's buffers have been widely used in cell/organ culture as biocompatible pH stabilizers. However, the emergence of adverse effects such as cellular uptake, autophagic activation, and cytotoxicity under light exposure raises concerns over its biocompatibility. Riboflavin in the cell culture medium produces reactive oxygen species (ROS) under light exposure, causing severe toxicity and disruption of normal cell functions. Zwitterionic betaines have been identified as a new generation of biocompatible pH buffers that do not exhibit these adverse effects.

Summary: In this study, a multifunctional decellularized scaffolds (DCS)-based vascular patch was designed for porcine vascular repair. By coating ammonium phosphate zwitter-ion (APZI) and poly(vinyl alcohol) (PVA) hydrogel on the surface of DCS, the mechanical properties and biocompatibility of the artificial vascular patch were improved. The artificial vascular patch was further decorated with a heparin (Hep)-loaded metal-organic framework (MOF) to inhibit blood coagulation and promote vascular endothelialization. The results showed that the obtained artificial vascular patch had suitable mechanical properties, good biocompatibility, and blood compatibility, making it an excellent vascular replacement material.

Summary: As a promising approach in translational medicine, the decellularization of discarded livers to produce bioscaffolds that support recellularization has potential in overcoming the limitations of conventional liver transplantation. In this study, the researchers investigated the use of matrix metalloproteinase (MMP) inhibition to preserve the extracellular matrix (ECM) during liver decellularization. The results demonstrated that the application of an MMP inhibitor significantly improved the preservation of ECM components and mechanical properties of the bioscaffolds, which supported cell viability and function in vitro. The study also confirmed that the MMP inhibition led to the inhibition of MMP2 and MMP9, providing a novel method to enhance ECM preservation during liver decellularization.

Alloying was found to be the most common, simple, and effective method for improving mechanical properties. Deformation processing and surface modification further improved the mechanical properties and biological activity of zinc alloys. Meanwhile, structural design could endow stents with special properties. Manufacturing zinc alloys with excellent properties and exploring their interaction mechanism with the human body are areas for future research.
