Pseudomonas aeruginosa is used as a prototypic organism. This innovative model mimics in vivo infection as bacterial proliferation is dependent on the ability of the bacterium to damage corneal tissue. Bioengineering Combination of Microstereolithography and Electrospinning to Produce Membranes Equipped with Niches for Corneal Regeneration Ílida Ortega1, Farshid Sefat1, Pallavi Deshpande1, Thomas Paterson1, Charanya Ramachandran3, Anthony J.

Prasad Eye Institute We report a technique for the fabrication of micropockets within electrospun membranes in which to study cell behavior. Specifically, we describe a combination of microstereolithography and electrospinning for the production of PLGA (Poly(lactide-co-glycolide)) corneal biomaterial devices equipped with microfeatures.
