Bio-Responsive Chemical Hydrogels

This section looks at three examples of actuation for bio-responsive chemical hydrogels and describes how these methods have been used in the development of biosensor, drug delivery and tissue scaffold systems. These three actuation examples are classified in Table 2.1 as follows changes in cross-finking density (1—8), electrostatic interactions (9—13) and molecular conformation (14, 15). 

1 Actuation Based on Changing the Cross-Linking Density 

1 Antigen Cross-linking Antigen- Poly-acrylamide Increased [8] 

3 Glucose Cross-linking Poly(GEMA) Increased [10]
