Summary: Maleic acid functionalized boron nitride nanosheets (BNNS-MA)/Na-Alginate composite with enhanced properties has been fabricated for the first time. The composite was driven by homogenous nano-integrations and chemistry of compatibilization. Compared to Na-Alginate, the BNNS-MA/Na-Alginate composites show significant enhancements in mechanical, UV-blocking, and antioxidant properties.

Summary: Novel PEF nonwovens were successfully produced by solution electrospinning and further modification, showing excellent performance. The hydrophilicity of the nonwovens was improved by sodium hydroxide treatment, and silver particles were deposited on the fiber surfaces through two-step modification with compounds and silver ions, exhibiting good antibacterial activity.

Summary: Peptide nanotechnology bridges the gap between materials and biological worlds by utilizing self-assembly of short-peptide building blocks. Hydrogels engineered from these short peptides show great potential in biomedical applications, but their weak mechanical properties and limited functional diversity need to be addressed. Nanoengineering the networks of these hydrogels by incorporating small molecules, polymers, and inorganic/carbon nanomaterials can enhance their mechanical properties and expand their functional diversity.

Summary: Nanoparticles have become widely used in electronics, medicine, and cosmetics, leading to daily exposure to a significant amount of nanoparticles. This study focused on the impact of a high dosage of hydroxyapatite nanoparticles on microvessels. The results showed that topical administration of these nanoparticles caused significant destruction of venules, arterioles, and capillaries. However, systemic administration did not affect microcirculation but altered biochemical parameters in the blood samples. These findings suggest the need for further investigation into the effects of nanoparticles on microcirculation and overall body homeostasis.

Summary: Human skin equivalents (HSEs) play a crucial role in tissue engineering. This study introduces a 3D-printed culture insert to apply a static radial constraint on HSEs and examines its effects on tissue characteristics. The results show that the diameter of the culture insert significantly influences tissue contraction, fibroblast and matrix organization, keratinocyte differentiation, epidermal stratification, and basement membrane formation. This study provides important insights for the design of skin tissue engineering.

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.

Summary: This review primarily discusses the relationship between contact lens discomfort (CLD) and the surface properties of contact lenses (CLs), specifically the coefficient of friction (CoF). The review emphasizes the importance of introducing a standardized protocol for measuring CoF and calls for a more precise evaluation of the relationship between surface properties and comfort in CLs users.
