2.2 Formulation of A-SA-Gel hydrogel
According to previous research [12], first, the 5% (w/v) SA and
10% (w/v) Gel solution was made in deionized water followed by mixing
both of them at the volume ratio of 1:1. Secondly, the albumin was added
and gently mixed with the SA/Gel solution at the volume ratio of 1:5 in
order to get the A-SA-Gel hydrogel. Finally, the hydrogel was stirred
constantly until free from air bubbles and stored in refrigerator
(4-10℃) for further use.
