“…9,10 In addition, their ability to bind and store substances and release them upon stimuli makes such systems potential candidates for drug delivery systems, not the least for protein and peptide drugs. 4,[11][12][13][14][15][16][17][18][19] When charged peptides interact with oppositely charged microgels, osmotic deswelling of the gel network takes place. However, due to the interplay between gel deswelling and peptide transport through the network, this is a complex process where a number of parameters effect the outcome in terms of functional properties such as the amount peptide incorporated, peptide distribution, and release rate.…”
