Potential use of alginate beads as a chondrocyte delivery vehicle and stepwise dissolving porogen in a hydrogel scaffold for cartilage tissue engineering
The submicron- or nano-sized pores and uncontrollable degradation of conventional hydrogels have severely constrained cell growth and neo-tissue formation. In this study, alginate beads are explored as both delivery vehicles of chondrocytes and stimuli-responsive porogens within hydrogel scaffolds for cartilage tissue engineering. A typical chondroitin sulfate (CS)–alginate beads composite gel (C...

Soft Matter, 2011, 7, 6426-6434. Development of an injectable system based on elastin-like recombinamer particles for tissue engineering applications,
An elastin-like recombinamer (ELR) containing the RGD cell adhesion domain was used to fabricate microparticles by an innovative and affordable process based on the use of superhydrophobic surfaces. Two microparticles types with different crosslinking extents were prepared. The biological response was tested using an osteoblast-like cell line (SaOs-2) performing pro...

[2015][Macromolecules, 2015, 48 (12), 3941–3948]Optimization of Broad-Response and High-Detectivity Polymer Photodetectors by Bandgap Engineering of Weak Donor–Strong Acceptor Polymers
A series of weak donor–strong acceptor polymers containing two different electron-deficient units (diketopyrrolopyrrole and thienoisoindigo) are synthesized and used in broad-response and high-detectivity polymer photodetectors. By adjusting the composition ratio of the two acceptors, the absorption spectra, energy levels, molecular stacking, and film morphology are affected, which in turn infl...

Tough biodegradable chitosan–gelatin hydrogels via in situ precipitation for potential cartilage tissue engineering
Tough porous chitosan-gelatin (CG)
hydrogels have been prepared through in
situ precipitation with the porosity and degradation rates tunable by
adjusting the preparation formulations. Compression tests showed a Young’s modulus of 3.25 MPa and a compressive strength of 2.15 MPa for the optimized C4G4 hydrogels, which are similar to or higher than those for human cartilages. Cyclic compression...

206. Electrospinning of poly (e-caprolactone-co-lactide)/Pluronic blended scaffolds for skin tissue engineering.
For skin tissue engineering, an ideal scaffold should mimic the natural extracellular matrix of the native skin. In this study, we reported a novel elastic sub-micron fiber scaffold blending poly (e-caprolactone-co-lactide) (PLCL) and Pluronic at different ratios by electrospinning. PLCL and Pluronic were co-electrospun with the ratio of 100/0, 99/1, 95/5, 90/10, 85/15, and 75/25. These scaffolds ...

Surface treatment of cellulosic paper with starch-based composites reinforced with nanocrystalline cellulose. Industrial & Engineering Chemistry Research
Starch-based composites have become promising materials for eco-friendly packaging applications because of their biodegradability and cost-effectiveness. However, the inherently poor mechanical and barrier properties of starch-based composite films hinder their market potential. Here, nanocrystalline cellulose (NCC) was isolated from cotton cellulose powders using sulfuric acid hydr...

Environmental pH-controlled loading and release of protein on mesoporous hydroxyapatite nanoparticles for bone tissue engineering
To explore the controlled delivery of protein drugs in micro-environment established by osteoblasts or osteoclasts, the loading/release properties of bovine serum albumin (BSA) depending on pH environment were assessed. The adsorption amounts over mesoporous hydroxyapatite (MHA) or hydroxyapatite (HA) decreased as the pH increased, negatively c...

In situ electroactive and antioxidant supramolecular hydrogel based on cyclodextrin/copolymer inclusion for tissue engineering repair
The injectable electroactive and antioxidant hydrogels are prepared from mixing the tetraaniline functional copolymers and α-cyclodextrin (α-CD) aqueous solution. UV-vis and CV of the copolymer solution showed good electroactive properties. The antioxidant ability of the copolymer is also proved. The gelation mechanism and properties of the system are studied by WAXD, DSC, and rheometer. The enc...
