Preliminary study on acrylated Pluronic F127-based hydrogels as artificial blood vessel materials

Continuous and Controllable Preparation of Sodium Alginate Hydrogel Tubes Guided by the Soft Cap Inspired by the Apical Growth of the Plant

“…Different compositions of SA hollow gel tubes were prepared, which are designated as SA x−y , where x denotes the concentration of SA, and y denotes the concentration of CaCl 2 . Hydrogel tubes were prepared by changing the volume of the soft cap (20,30,40, and 50 μL), the injection rate (300, 500, 700, 900, and 1100 μL/min), or the gelation time (1, 3, 5, 7, 9, and 25 min) (at the start of injection to count).…”

“…Unlike bulk hydrogel, the hydrogel tube had a core–shell structure with a hollow core surrounded by a hydrogel wall. The special hollow core structure provided hydrogel tubes with different functions from bulk hydrogel, such as connection, guidance, and transportation in an aqueous environment. − They had potential applications in some areas such as artificial blood vessels, , tissue engineering, − peripheral nerve injuries, and so on. The unique physicochemical properties have attracted widespread attention.…”

Mechanical Enhancement of the Gelatin/Poly(zinc acrylate) Hydrogel Stent in Bile

“…Owing to its distinctive softness, intrinsic biocompatibility, bioactivity, and modifiability, 1−3 hydrogel as a hydrophilic material has been widely studied in recent decades and developed as an excellent material in the biomedical field, 4−6 including soft robots, 2,7,8 drug delivery, 9−11 tissue engineering, 12 wound healing, 13 and vascular and nonvascular stents. 14,15 Hydrogels with or without bioactive molecules could be used as wound dressings and realized the acceleration of the healing of skin wounds.…”
