E. coli Extracellular Matrix: A Tunable Composite With Hierarchical Structure

Advanced Materials, Volume 38, Issue 43, 3 August 2026.
The complex composite‐like mechanical behavior of E. coli biofilm matrix is the result of a synergic contribution of the rigid curli and swelling pEtN‐cellulose, and emerges from specific ratio and assembly conditions. The interactions between the two fibers govern biofilm hydration and characteristic wrinkling patterns, providing crucial insights for ...

Liquid Crystal Elastomers Filaments for Adaptive Textiles and Soft Robotics: A Processing‐Centric Review

Macromolecular Rapid Communications, Volume 47, Issue 15, 4 August 2026.
Liquid crystal elastomer (LCE) filaments are fabricated through extrusion with in‐process UV curing, enabling controlled flow alignment and network locking of mesogens. The resulting structure responds to thermal or optical stimuli, inducing molecular reorientation and macroscopic contraction.

Development of an alginate–chitosan biopolymer composite with dECM bioink additive for organ-on-a-chip articular cartilage

Scientific Reports
In vitro use of articular cartilage on an organ-on-a-chip (OOAC) via microfluidics is challenging owing to the dense extracellular matrix (ECM) composed of numerous protein moieties and few chondrocytes, which has limited proliferation potential and ...

Injectable Short Nanofiber Fragments Enable Conformal Fibrous Scaffolds for Tissue Engineering on Complex Surfaces

Macromolecular Rapid Communications, Volume 47, Issue 15, 4 August 2026.
Short nanofiber fragments (SNFs) derived from electrospun PDLA/gelatin (PG) mats dynamically reassemble into conformal fibrous networks on complex substrates. This approach overcomes the geometric limitations of conventional electrospinning, enabling uniform surface coverage, enhanced wettability, and cytocompatible scaffold formation, thereby offering

3D Liver Fibrosis Models in Lab: A Novel Modality for Drug Screening

Pharmacology Research &Perspectives, Volume 14, Issue 4, August 2026.
ABSTRACT Liver fibrosis is the common consequence of liver injury caused by a variety of chronic liver disorders. This condition leads to the development of more severe complications, particularly cirrhosis and hepatocellular carcinoma. Despite abundant studies, the fundamental cell and molecular mechanisms of liver fibrosis are still unknown.

Recombinant Human Collagen in Clinical Medicine

Journal of Cosmetic Dermatology, Volume 25, Issue 8, August 2026.
ABSTRACT Background Collagen is the dominant structural protein of vertebrate connective tissues and a central biomaterial in skin, cornea, tendon, cartilage, bone, vessel, oral mucosa, and wound repair. Traditional collagen products have largely been extracted from bovine, porcine, fish, or other animal tissues.

Strategies for the Selection and Application of Biological Scaffolds in Organ‐on‐a‐Chip Systems

ChemBioChem, Volume 27, Issue 13, 14 July 2026.
Organ‐on‐a‐chip (OoC) serves as a promising microphysiological platform for drug screening, disease modeling, and toxicity assessment. Biomimetic scaffolds are core components that determine the performance of OoC systems by mimicking the in vivo extracellular microenvironment.
