Neurotech’s proprietary encapsulated cell therapy. Encapsulated cell implants consist of living cells encapsulated within semipermeable polymer membranes and supportive matrices: (A) longitudinal view of cell-containing implant: (B) intraocular placement of an encapsulated cell implant Intraocular Drug Delivery – Chapter 08, Fig 2
Chamber A contains a diffusant that is full dissolved in A and is at a higher concentration than in chamber B, which is a perfect sink. Diffusion from A to B is driven by the concentration difference between the two chambers. • (B) Chamber A contanins a suspension of a diffusant. As the diffunsant moves to chamber B, the decrease in concentration can be off-set by the dissolution of the suspended particles, which acts to maintain the concentration gradient Intraocular Drug Delivery – Chapter 01, Fig 3
