#Elsevier and #ScienceJournal – Polymer microsphere inks for semi-solid extrusion 3D printing at ambient conditions
Abstract https://www.sciencedirect.com/science/article/pii/S1751616124004156?dgcid=author Extrusion-based 3D printing methods have great potential for manufacturing of personalized polymer-based drug-releasing systems. However, traditional melt-based extrusion techniques are often unsuitable for processing thermally labile molecules. Consequently, methods that utilize the extrusion of semi-solid inks under mild conditions are frequently employed. The rheological properties of the semi-solid inks have a substantial impact […]
Wiley – Experimental investigation of PCL-based composite material fabricated using solvent-cast 3D printing process
Abstract https://onlinelibrary.wiley.com/doi/abs/10.1002/pat.6416?casa_token=WQcKEetHLSgAAAAA%3Alg7G6z9JBMJM0wxuWkL16agBgvuFZag7mTRWy7pvGBYfCzHwxTvcgOtXUfH7yVbRAa9NuSTpdua5V7E Bone tissue engineering relies on scaffolds with enhanced mechanical properties, achievable through 3D printing techniques. Our study focuses on enhancing mechanical properties using a solvent-cast 3D printing method. For this, poly-ε-caprolactone (PCL) reinforced with polyhydroxybutyrate (PHB), and synthetic fluorapatite (FHAp) nanopowders were utilized, immersed in a solution of dichloromethane (DCM) and dimethylformamide (DMF).

Springer – Spatial Engineering of Mammary Epithelial Cell Cultures with 3D Bioprinting Reveals Growth Control by Branch Point Proximity
Abstract https://link.springer.com/article/10.1007/s10911-024-09557-1 The three-dimensional (3D) structure of the ductal epithelium and the surrounding extracellular matrix (ECM) are integral aspects of the breast tissue, and they have important roles during mammary gland development, function and malignancy. However, the architecture of the branched mammary epithelial network is poorly recapitulated in the current in vitro models. 3D bioprinting […]
Royal Society of Chemistry / Green Chemistry – Employing photocurable biopolymers to engineer photosynthetic 3D-printed living materials for production of chemicals
https://pubs.rsc.org/en/content/articlehtml/2024/gc/d3gc04264b#fn1 Abstract Photosynthetic microorganisms, such as cyanobacteria and microalgae, have great potential as living cell factories for chemical and fuel production. Immobilisation of cells is an effective technique for enhancing productivity and longevity of the production system, as well as aiding in the separation of cells from the medium. Alginate crosslinked with divalent ions is […]
Advanced functional materials – Bioprinting Macroporous Hydrogel with Aqueous Two-Phase Emulsion-Based Bioink: In Vitro Mineralization and Differentiation Empowered by Phosphorylated Cellulose Nanofibrils
Abstract https://onlinelibrary.wiley.com/doi/full/10.1002/adfm.202400431 Aqueous two-phase emulsion (ATPE)-based bioinks, a creative innovation for bioprinting, enable the fabrication of complex 3D cell-laden hydrogels with macroporous structure, which promote cellular activities within the scaffold. However, these bioinks intrinsically lack stability and specific biofunctionality, potentially limiting their application for targeted tissue engineering. This study proposes a new perspective by introducing […]
Materials Advances – A comprehensive study on rheological properties of photocrosslinkable gallol-metal complexed hyaluronic acid-based biomaterial inks
Abstract https://pubs.rsc.org/en/Content/ArticleLanding/2024/MA/D4MA00273C This study describes the development of bioadhesive hydrogels as biomaterial inks, which combine catechol chemistry and metal coordination using gallic acid and hyaluronic acid. By controlling the phase of gelation, the properties of hydrogels can be modulated through pH and Fe3+ ion concentrations, thus allowing for diverse coordination states within the polymeric network. The […]

SCIENCE SERIES PART II: 3D bioprinting for meniscus repair – Abstract
The menisci are important cartilage structures located on each side of the knee joint, as they provide the required cushion and shock absorbance, enhancing knee stability and distributing the weight of the body on the lower leg. They can bear up to five times the body weight during daily activities! Due to their poor blood […]
