Abstract Artificial lacrimal bypass tube (LBT) implantation has been widely used for treating proximal drainage obstruction. However, its long‐term clinical success is still constrained by the frequent dislodgement due to mismatch mechanical properties surrounding soft tissue and poor fusion along smooth surface. Aiming tackle this challenge, here a method of 3D printing LBT reported that comprises three key features: 1) adaptability match with characteristics tissue, 2) tailorable surface porosity promote binding, 3) customization accommodate individual patient's anatomies. Using hydrogel‐based biocompatible ink, LBTs are printed initially rigid (compressive Young's moduli E : ≈1.6 GPa) ease surgical insertion but become compliant ( 0.16–3.36 MPa) after better tissue. The inherent manufacturing flexibility enables integration porous shell prompt infusion ensure integrity. Ultimately, in vivo intramuscular orthotopic studies demonstrate exhibit excellent tolerance rabbits minimal inflammation observed, shells help significantly reduce dislocation rate from 80% 13.3%.

The review explores the potential of asiaticoside-loaded bioscaffolds to improve management hyperglycemic wounds, particularly diabetic foot ulcers (DFUs). Asiaticoside, sourced from Centella asiatica, possesses properties that address DFUs’ healing challenges: insufficient angiogenesis, persistent inflammation, and delayed tissue regeneration. By incorporating asiaticoside into bioscaffold 3D designs including hydrogels, microneedle arrays, nanofibrous meshes, therapeutic efficacy is optimized. This examines mechanisms in wound (collagen production, angiogenesis modulation, inflammation reduction, cell migration proliferation) based on vitro vivo studies. Asiaticoside also demonstrates synergistic abilities with other biomaterials, creating possibility more effective therapies. While preclinical research promising, clinical trials are crucial evaluate safety patients DFUs. Asiaticoside-loaded a significant development may aid treating complications. Their ability offer individualized treatment plans has enhance quality life those who suffer diabetes. thorough literature search (2019–2024) across multiple databases, excluding secondary non-English articles.

Abstract Customizable 3D‐printed biopolymer hydrogels, highly sought after for diabetic wound management, face challenges in clinical application due to weak physical crosslinking within their constituent inks. In this study, a novel chitosan‐based hydrogel ink with dense yet reversible network is subtly designed the rapid situ fabrication of personalized dressing. This robust established through multiple electrostatic and hydrogen bonding interactions between unique carboxymethyl chitosan nanoclay, further reinforced by introduction amide bonds, which act as double bond donors/acceptors. Benefiting from network, low nanoclay content exhibits remarkable self‐supporting properties, enabling high‐fidelity, large‐scale, complex 3D printability without additional processing, while substantially retaining its inherent rheological properties autoclave sterilization incorporation active components. Given these advantages, multifunctional printable can be rapidly constructed on wounds. Simultaneously, demonstrates biodegradability, anti‐swelling, appropriate mechanical along vitro antibacterial pro‐angiogenic capabilities, leading effective healing vivo. work offers new strategy creating inks paves way developing advanced dressings.
