Abstract Skin is one of the largest and most important organs in human body. When faced with a large, full-thickness skin burn, there not enough healthy to graft. In this case, we can replace our biomaterials. Due its characteristics water permeability, antibacterial properties, biocompatibility, self-debridement, so on, hydrogel undoubtedly better alternative material. Among methods preparatio...

OBJECTIVES This study sought to determine whether alginate biomaterial can be delivered effectively into the infarcted myocardium by intracoronary injection to prevent left ventricular (LV) remodeling early after myocardial infarction (MI). BACKGROUND Although injectable biomaterials can improve infarct healing and repair, the feasibility and effectiveness of intracoronary injection have not ...

hydrogels are introduced to modem medicine as novel materials suitable for a variety ofbiomedical applications. studying hydrogels as novel biomaterials has become a fast-developingand exciting research field during the last two decades. these interesting biomaterials have found awide range of application including contact lenses, vehicles for drug delivery and scaffold in tissueengineering and...

Stimuli-responsive hydrogels can be used to convert miniature pressure sensors into novel chemomechanical sensors via confinement of the hydrogel sample between a porous membrane and a piezoresistive diaphragm. Chemomechanical sensors could prove beneficial in a variety of applications, including continuous monitoring of bioreactors and biomedical systems. In this study, one hydrogel compositio...

Artificial reconstruction of three-dimensional (3D) hydrogel microstructures would greatly contribute to tissue assembly in vitro, and has been widely applied in tissue engineering and drug screening. Recent technological advances in the assembly of functional hydrogel microstructures such as microfluidic, 3D bioprinting, and micromold-based 3D hydrogel fabrication methods have enabled the form...

We report the first in situ quantitative visualization and characterization of electro-induced chitosan hydrogel growth in an aqueous environment. This was enabled with a pair of sidewall electrodes within a transparent fluidic system, which allowed us to resolve the electrogelling mechanism and interpret the dominant causes responsible for the formation and density distribution of the deposite...
