Summary: Due to the limited healing capacity of the meniscus, there is a clinical need for the development of constructs that replicate meniscal tissue organization for better repair. Suspension bath bioprinting technology allows for the fabrication of complex structures using non-viscous bioinks. In this study, anisotropic constructs with embedded hydrogel fibers were printed using suspension bath printing and showed improved cell and collagen alignment, as well as enhanced tensile moduli compared to constructs without fibers. This work advances biofabrication for meniscal tissue repair.

Summary: This paper investigates the use of hydrogel materials in biomedical and flexible optical sensors. Two hydrogel structures, film and fiber, were prepared to achieve low threshold and flexible random lasers. The random laser is attributed to light scattering from the porous structure of the hydrogel. The hydrogel film and fiber showed tunable random lasing wavelengths within a temperature range. The bending strain and stretching of the hydrogel structures also influenced the random laser threshold. The hydrogel fiber structure exhibited better temperature sensing performance and flexibility compared to the thin film structure. This research opens up possibilities for the application of random lasers in photothermal therapy, ion detection, and biosensing.

Summary: Understanding the interaction between cells and nanoparticles is crucial for assessing their potential hazard. Quantifying and interpreting dose-response relationships through mathematical models in cell culture experiments is common, but these models need to consider the meniscus effect caused by the aqueous cell culture media. This study addresses the impact of the meniscus on nanoparticle dosimetry, presents an advanced mathematical model, and suggests practical solutions to improve reproducibility and harmonization.

Summary: In this study, the optically driven acoustic modes and nonlinear response of multilayered spherical plasmonic hetero-nanoparticles were investigated. These nanoparticles, composed of alternating layers of gold and silica, exhibited a broadband nonlinear optical response from visible to near-infrared wavelengths. Additionally, they served as a tunable optomechanical system with mechanically decoupled layers, allowing for selective switching of different acoustic modes by tuning the excitation wavelength. These findings not only enhance our understanding of the internal structure of composite plasmonic nanoparticles but also provide an additional degree of freedom for controlling their nonlinear optical and mechanical properties.

Summary: We have developed photocurable liquid crystal hydrogels with bone extracellular matrix (ECM)-like liquid crystal state and viscoelasticity, as well as different chargeability. The prepared liquid crystal hydrogels showed remarkable cell affinity and osteogenic ability due to their ECM-like liquid crystal state and viscoelasticity. The hydrogel with negatively charged particles exhibited better cell adhesion, spreading, and osteogenic differentiation compared to the hydrogel with positively charged particles. This work provides a promising strategy for bone repair.
