Abstract: A long-term delivery system for age-related macular degeneration (AMD) that can address the multifactorial nature of the disease. A polyurethane nanocapsule is disclosed that includes encapsulated molecules that treat AMD. The molecules can be passively delivered from the polyurethane nanocapsules over many weeks or months and/or can be tuned, non-invasively, using ultrasound to trigger the release the molecules from the polyurethane nanocapsules repeatedly in an on-demand and predictable manner. These nanocapsules have the potential to change the way diseases are treated and provide a new ultrasound-triggered drug delivery platform.

Abstract: A process of simply, cheaply, and reproducibly creating complex tissue models using screen printing and the tissue model prepared using the screen printing process. These models are amenable to high throughput screening. They will allow the study of components of disease progression and can be used for screening therapies.

Abstract: One of the significant challenges to translation of intravenously administered nanomaterials has been complement-mediated infusion reactions which can be lethal. Slow infusions can reduce infusion reactions, but slow infusions are not always possible in applications like controlling bleeding following trauma. Nanocapsules based on polyurethane are introduced as candidates that do not substantially activate complement protein C5a and the PEGylation and functionalization of the nanocapsules with the GRGDS peptide to create a new class of hemostatic nanomaterials is disclosed. Advantageously, the nanocapsules substantially avoid complement-mediated infusion reactions, promote faster clotting than controls, maintain maximum clot firmness, and do not activate pro-inflammatory cytokines.

Abstract: A pharmaceutical composition is provided comprising microparticles encapsulating high weight percent active agent and providing sustained release over a prolonged period of time of active agent levels bioequivalent to direct administration of active agent. Polymeric microparticle compositions containing one or more active agents, and methods of making and using thereof, are described. The microparticles are optimized for the agent to be delivered, so that the hydrophobicity or hydrophilicity of the polymer and charge of the polymer maximizes loading of the agent, and the selection and molecular weight of the polymers maximize release of an effective amount of the active agent for the desired period of time.

In a preferred embodiment, the microparticle compositions contain one or more active agents useful for managing elevated intraocular pressure (IOP) in the eye. Relatively hydrophilic, and preferably carboxylated, polymeric materials such as PLGA are used for a drug such as timolol maleate, which is relatively water soluble, to increase drug loading. Higher molecular weight polymers, as well as the ratio of LA (which has a longer degradation time, up to one to two years) to GA (which has a short degradation time, as short as a few days to a week), are used to provide release over a longer period of time.

Abstract: A method of producing a tissue engineering construct. The method includes providing a population of embryonic stem cells, seeding the embryonic stem cells on a cell support matrix, and exposing the embryonic stem cells to at least one agent selected to promote differentiation of the stem cells along a predetermined cell lineage or into a specific cell type. The step of exposing may be performed before or after the step of seeding.
