Abstract: Described herein are medical film materials that incorporate one or more neuro-regenerative drugs into a polymer film. The polymer film includes a copolymer of lactide and caprolactone. The neuro-regenerative drug includes the macrolactam immunosuppressant FK506. The film is configured such that when placed under physiological conditions, the neuro-regenerative drug is released in an extended, substantially linear fashion for a period of at least 30 days.

Abstract: A split thin-flow separations device can include a fluid channel having an inlet zone, an outlet zone, and a transport region between the inlet zone and outlet zone. The inlet zone includes a sample inlet and a carrier fluid inlet which are fluidly separated by an inlet splitter to minimize mixing of fluids from respective inlets in the inlet zone. The transport region can be a substantially open channel. Similar to the inlet zone, the outlet zone can include a sample outlet and a carrier outlet which are fluidly separated by an outlet splitter to segregate portions of a fluid into each of the two outlets as the fluid enters the outlet zone. A plurality of cross-flow inducers can also be oriented along a wall of the fluid channel in the transport region. The cross-flow inducers are oriented to form a cross-flow field across the transport region.

Abstract: A method for making a microstructure includes: providing a film (100) on a release liner (110); feeding the film through a cutting plotter (10); cutting the film with a knife blade (34) of the cutting plotter to form a microstructure pattern; peeling the microstructure pattern from the release liner; and transferring the microstructure pattern to a substrate (170). The cutting plotter for making microstructures includes a knife head with a knife blade disposed adjacent a feed mechanism (20), a motor (42) and control system coupled to the knife head for selectively moving the knife head in relation to the film, and the control system and the knife head having an addressable positioning resolution less than approximately 10 ?m.
