The preparation of cellulose hydrogels via coagulation depends on the properties of the pre-gel cellulose solutions. In this approach, cellulose solutions are generally stable. The solutions for preparing cellulose hydrogels include cellulose in DM Ac/...

Another important aspect related to the biochemical field is the need for systems that ensure prolonged, controlled, and tunable release of drug or therapeutic compounds. Vulic and Shoichet (2012) have developed a delivery strategy based on synthesis of hydrogels prepared with functionahzed polymer chains. Their aim was the production of a structure that could deliver a variety of bioactive proteins with a different rate of release. Specifically, methyl cellulose was linked, thorough binding peptides. 

Both, Wan et al. and Hutchens et al. prepared HA by using a biomimetic synthesis approach, with a bacterial cellulose hydrogel as template [64, 65]. Their results indicated that spherical HA particles comprised of nanosized crystallites...

Figure 19.11 Phase-contrast light images of cellulose hydrogel films and commercial PS dish as control. Hydrogel films were prepared with 6 wt% and 12 wt% of LiCl in DMAc and then the cell culture time was 4 h, 24 h and 48 h on the hydrogels.

Fig. 5. Scanning electron micrographs of hoUow fiber dialysis membranes. Membranes in left panels are prepared from regenerated cellulose (Cuprophan) and those on the right from a copolymer of polyacrylonitrile. The ceUulosic materials are hydrogels and the synthetic thermoplastic forms a microreticulated open cell foam with a tight skin on the inner wall. Pictures at top are membrane cross sections those below are of the wall region. Dimensions as indicated.
