Noodles. 10 mg/mL solutions were prepared as described above using either NaOH or TBAOH. Gel noodles were formed using the injection of 10 μL of 2NapFF-Na or 2NapFF-TBA solution into 2 mL of trigger medium (50 mM CaCl2 adjusted to pH 10.5 with the corresponding hydroxide (NaOH or TBAOH)) in 3.5 mL glass vials. A 2-20 μL pipette was used to perform a static injection as has been detailed in previously published work.
