Summary: This study introduces a simple and green sonochemical process for PDA coatings, which can be obtained independent of solution pH and gas nature. The rate of film deposition by high frequency ultrasound is found to be faster than traditional methods, enabling the creation of PDA coatings in neutral or acidic aqueous solutions.

Summary: Cardiac medical devices (CMDs) are crucial for patients with compromised cardiac capacity or activity. The materials used in CMDs must possess strength, stiffness, rigidity, and corrosion resistance. Furthermore, the biocompatibility of the materials plays a critical role in the success of CMDs, as it can lead to problems such as hemocompatibility issues and infection.

Summary: Polyactic acid (PLA) is commonly used in the manufacturing of bone tissue engineering scaffolds. Different strategies, such as using ceramic particles and surface modification methods, have been proposed to enhance the biofunctionality of PLA scaffolds. This study investigated the degradation profile of 3D-printed PLA scaffolds containing beta-tricalcium phosphate (beta-TCP) and calcium carbonate (CaCO3) particles under hydrolytic conditions, and evaluated the effect of plasma treatment and Aloe vera extract coating as surface modification methods. The results show that the proposed composite scaffolds effectively maintained the pH level in the surrounding medium and did not have any significant effects on the morphology and mechanical properties of the structures. Therefore, these samples show potential for further research as candidates for bone tissue regeneration.

Summary: This study focused on the design and synthesis of catechol-derived ATRP initiators containing the 2-bromoisobutyryl moiety, and investigated the impact of structural changes on initiator immobilization and subsequent ATRP performance. The results showed that changes in the length of the linker unit bearing the 2-bromoisobutyryl moiety, the introduction of a free amine group, or the replacement of the amide with an ester had profound effects on the ability of the molecule to deposit ATRP-initiator-modified PDA coatings, as well as the subsequent SI-ATRP performance.

Summary: This study analyzed the correlation between surface chemistry of genetically engineered bacteriophages and the properties of bacteriophage-based optoelectronic noses, demonstrating controllable reactivity through genetic engineering. Phages advantageous in distinguishing VOCs were selected through HCA, with the differences verified through optimized geometry calculated by DFT. The study confirmed the importance of tryptophan-based and histidine-based genetically engineered phage films in distinguishing VOCs used to evaluate peach freshness, and applied this to design a field-applied phage-based optoelectronic nose for measuring fruit freshness.

Summary: In situ generation of antibacterial and antiviral agents on surfaces through enzyme catalytic activity is an effective eco-friendly approach. A stable and active AcT-based coating was developed by incorporating AcT into a polydopamine matrix, yielding high activity and stability for reuse. This enzyme-polymer composite technique may serve as a general strategy for preparing antibacterial and antiviral surfaces in various applications.

Summary: This study explores the application of surface plasmon resonance in evaluating polystyrene modification efficiency to enhance biomolecule adsorption. It facilitates the development of advanced immobilization strategies for biofunctionalization of the polystyrene surface. Using a thin layer of polystyrene over the SPR chip surface allows for a detailed characterization of biomolecular interactions at the polystyrene surface.

Summary: Hip and knee joint replacements are common and successful surgeries, but the release of metallic ions and particles from the implants can cause hypersensitivity and tissue necrosis. Coatings have the potential to improve implant properties and act as barriers to inhibit ion release. There are commercially available coatings for clinical use and ongoing research on new coatings. Adhesion of coatings remains a concern, but zirconium and TiNbN coatings have shown comparable results to traditional implants in terms of revision numbers and allergy symptom relief.
