摘要:
An active needle device for fluid injection or extraction includes at least one hollow elongated shaft defining at least one channel. The channel provides communication between at least one input port and at least one output port of the needle device. At least one active component such as a sensor or actuator is placed or integrated into the elongated shaft. The needle device can include a macroneedle, a microneedle, or an array of macroneedles or microneedles. The microneedles can be fabricated on a substrate which can remain attached to the microneedles or be subsequently removed. The active component can facilitate biochemical, optical, electrical, or physical measurements of a fluid injected or extracted by the needle device.

摘要:
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 μm.

摘要:
In general, embodiments of the present invention relate to a bioluminescence-based point of care device that is made up of at least one reaction well (89) that contains a bioluminescent reagent for a luminescent reaction, sample well (80), sample collection well (84), and reagent well (87). A sample is introduced into the reaction wells (89), where it dissolves the reagents and initiates the luminescent reaction, where a luminescence signal is then transmitted through a window to a photo detector.
