“…Among therapeutics, adsorbent coatings for blood perfusion,208–211 hemodialysis membranes,212–216 blood oxygenators,214 degradable drug delivery systems, medicated and soft contact lenses should be mentioned 217–221. Implants include intraocular lenses,222, 223 artificial corneas,224–228 coating for drainage tubes and stents,229–232 vitreous humor replacements,233 soft tissue substitutes/replacements,126, 234, 235 burn dressing,236–241 bone ingrowth sponges,242 plastic surgery,243–245 scleral buckling implants for retinal surgery 246–249. Finally, as pure TE products, temporal artificial skin substitutes, membranes used to prevent postoperation adhesion and to promote healing,250 HGs produced in vivo by using in situ photo‐polymerization,9, 10, 35, 37, 202, 262, 263, 275, 276, 279 HGs for cell encapsulation28, 29, 45, 52, 53, 203 and consequently corporal and extra‐corporal bioartificial or biohybrid organs (e.g., artificial pancreas, artificial liver)251–260 have been produced and investigated.…”
