Fe3O4@astragalus polysaccharide core-shell nanoparticles for iron deficiency anemia therapy and magnetic resonance imaging in vivo [PDF]

arXiv, 2018
Fe3O4@astragalus polysaccharide core-shell nanoparticles (Fe3O4@APS NPs) were demonstrated to be an efficient therapeutic drug for treating iron deficiency anemia (IDA) in vivo. The Fe3O4@APS NPs have been synthesized using a two steps approach involving hydrothermal synthesis and subsequent esterification.

Films of Bacteria at Interfaces (FBI): Remodeling of Fluid Interfaces by Pseudomonas aeruginosa [PDF]

arXiv, 2017
Bacteria at fluid interfaces endure physical and chemical stresses unique to these highly asymmetric environments. The responses of Pseudomonas aeruginosa PAO1 and PA14 to a hexadecane-water interface are compared. PAO1 cells form elastic films of bacteria, excreted polysaccharides and proteins, whereas PA14 cells move actively without forming an ...

Imine Crosslinked, Injectable, and Self‐Healing Fucoidan Hydrogel with Immunomodulatory Properties

Advanced Healthcare Materials, EarlyView.
This study develops an injectable fucoidan‐based hydrogel with tunable properties for tissue engineering. By oxidizing fucoidan (OFu) to introduce aldehydes, imine crosslinks are formed with amine‐containing polymers, enabling self‐healing, injectability, and long‐term stability (≥28 days). The OFu‐gelatin hydrogel demonstrated biocompatibility, immune‐

Biofunctionalization of ADA‐GEL Hydrogels Based on the Degree of Cross‐Linking and Polymer Concentration Improves Angiogenesis

Advanced Healthcare Materials, EarlyView.
The biocompatibility of alginate dialdehyde (ADA) and gelatin (GEL) hydrogels cross‐linked with human transglutaminase (hTG) is demonstrated in vivo with a high degree of stability and angiogenic potential. The additional enzymatic cross‐linker hTG and the increased concentration improve stability and angiogenic potential. The X‐ray microscopy (XRM) is

Overcooked agar solutions: impact on the structural and mechanical properties of agar gels [PDF]

arXiv, 2016
Thermoreversible hydrogels are commonly prepared by cooling down to ambient temperature, aqueous polymer solutions first brought to a boil. The incubation time of the polymer solution at such a high temperature is traditionally kept to a minimum to minimize its impact on the subsequent gelation. Here we study the effect of a prolonged heating of a 1.5\%
