A set of 104, 103, and 100 Å Waters columns conditioned at 35 ◦C was used to elute samples at a 1 mL min−1 flow rate with HPLC-grade dimethylformamide with 1% of BrLi as the solvent. Polystyrene standards were used for the calibration. 2.4.2. Proton Nuclear Magnetic Resonance ...
To actively control their mechanical performance and degradation rate and to eliminate the requirement of toxic crosslinking agents, methacrylate groups are desirably grafted onto gelatin backbones, yielding photocrosslinked hydrogels based on gelatin methacryloyl (GelMA) [11–15]. Furthermore, gelatin ...
This system can create 3D printed tissues by stacking 2D patterns of the desired shape and cellular organization through a layer-by-layer process. The dispensing volume from the syringe is regulated by adjusting the dispensing rate (e.g., by changing the level of pneumatic pressure, speed of ...
