Medical dressings include a non-woven polymeric nanofiber mat embedded within a chitosan hydrogel matrix. The dressings may be obtained by electro spinning of polymeric nanofibers and thereafter incorporating a chitosan hydrogel into interstices of the mat by vacuum or positive pressure assistance. The resulting medical dressings may be optically transparent (e.g., at least about 50% up to about 95% light transmittance), flexible, and mechanically robust. The dressings may also incorporate self-adhesion promoters to allow self-adhesion to biological tissue, e.g., ocular surfaces, and/or therapeutic agents which are capable of delivering therapeutics (e.g. stem cells, drugs and the like) to the tissue surface. The dressings are especially useful as ocular bandages for the treatment and repair of ocular wounds.

The present invention relates to the formation of hydrogels from poly-amino acids designed from the -aggregation-prone region of functional amyloidogenic proteins that self-assemble to form a three-dimensional nanofibril matrix. Further, these water entrapped meshwork can be modulated by various physico-chemical cues. The present invention also explores the use of the designed hydrogels as cell and tissue adhesive biomaterial for tissue engineering applications. The present invention also relates to the application of functional amyloid hydrogel including but not limited to 3D tumoroid model for anticancer drug testing, optimization of drug dosage including drug-resistant tumors, repurposing of existing drugs, and patient-derived organoid. The present invention also describes the use of functional amyloid hydrogel as a depot for controlled and sustained release of therapeutics and biologic agents encapsulated within the same. The present invention also provides a moist highly water retentive material as reservoir of wound exudates thereby promotes healing.
