(a) Energy minimized geometrically conformation displaying the bipolymeric complex of (a) alginate (tubes) and chitosan (ball‐and‐tube); (b) chitosan (ball‐and‐tube) and hyaluronic acid (stick); and (c) hyaluronic acid (stick) and alginate (tubes) after molecular mechanics simulations. Color codes for elements: carbon (cyan), hydrogen (white), nitrogen (blue), and oxygen (red). (b) Energy minimized geometrically conformation displaying the tripolymeric complex of alginate (tubes), chitosan (ball‐and‐tube), and hyaluronic acid (stick) after molecular mechanics simulations. Color codes for elements in (a): carbon (cyan), hydrogen (white), nitrogen (blue), and oxygen (red). Color codes for structures in (b): alginate (red), chitosan (blue), and hyaluronic acid (yellow) (Reference 14; reproduced with permission from springer nature © 2015)
