background

● Development of a totally artificial collagen surrogate as a biomaterial
● Requirements of biocompatibility, polymer properties and specific bio- functions
● Processability to medical devices

summary

● Polymerization of the collagen-like peptides by cross-linking via disulfide bonds
● Functionalization by incorporating bioactive sequences derived from native collagen
● Process into a transparent membrane by a drying/rehydration of the gel

predominance

● Safe (free from zoonotic pathogens) and steady supply
● Tunable functionalization
● Flexible processing

application/development

● As cell culture substrates
● As medical devices:
   Ophthalmology : as an artificial cornea;  as dressings for retinal
   Injury other applications in dermatology, orthopedics, cardiovascular medicine,  etc...
