A Pressure‐Sensitive, Repositionable Bioadhesive for Instant, Atraumatic Surgical Application on Internal Organs

Advanced Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Aug. 15, 2024

Abstract Pressure‐sensitive adhesives are widely utilized due to their instant and reversible adhesion various dry substrates. Though offering intuitive robust attachment of medical devices on skin, currently available clinical pressure‐sensitive do not attach internal organs, mainly the presence interfacial water tissue surface that acts as a barrier adhesion. In this work, pressure‐sensitive, repositionable bioadhesive (PSB) adheres organs by synergistically combining characteristic viscoelastic properties behavior hydrogel bioadhesives, is introduced. Composed copolymer, PSB absorbs enable wet such heart lungs, removal after use without causing any damage. The PSB's capabilities in diverse on‐demand surgical analytical scenarios including stabilization soft integration bioelectronic rat porcine models, demonstrated.

Abstract Combining emulsion templating with additive manufacturing enables the production of inherently porous scaffolds multiscale porosity. This approach incorporates interconnected materials, providing a structure that supports cell ingrowth. However, 3D printing hierarchical structures combine semi-micropores and micropores remains challenging task. Previous studies have demonstrated using carefully adjusted combination light absorbers photoinitiators in resin can produce open surface porosity, sponge-like internal structures, resolution about 150 µ m. In this study, we explored how varying concentrations tartrazine (0, 0.02, 0.04, 0.08 wt%) as absorber affect acrylate-based polymerized medium phase emulsions fabricated via vat photopolymerization. Given importance for tissue engineering regenerative medicine, tested behavior on these 3D-printed disk samples MG-63 cells, examining metabolic activity, adhesion, morphology. The wt% tartrazine-containing sample (008 T) best proliferation adhesion. To show high (HIPE) be used to create complex biomedical applications, trabecular bone based microCT imaging. These were further evaluated migration, followed by analysis after 60 days culture. research demonstrates HIPEs print mimics manufacturing, which could developed lab-on-a-chip models healthy diseased bone.
