Abstract: A microfluidic device is provided for delivering a drug to an individual. The microfluidic device includes a body that defines a reservoir for receiving the drug therein. A valve interconnects the reservoir to an output needle that is insertable into the skin of an individual. A pressure source urges the drug from the reservoir toward the needle. The valve is movable between a closed position preventing the flow of the drug from the reservoir to the output needle and an open position allowing for the flow of the drug from the reservoir to the output needle in response to a predetermined condition in the physiological fluids of the individual.

Abstract: A microfluidic device is provided for regulating the temperature of a sample fluid flowing therethrough, as well as, a method of regulating the temperature of the sample fluid flowing through the microfluidic device. The microfluidic device includes a body member defining a fluid channel for allowing the sample fluid to flow therethrough and a first regulating channel. A regulating fluid having a predetermined temperature flows through the regulating channel adjacent the fluid channel so as to effectuate a heat exchange with the sample fluid flowing through the fluid channel to regulate the temperature thereof.

Abstract: A microparticle storage and delivery device is provided for allowing an individual to selectively dispense a dosage of a microparticle. The device includes a hydrogel string loaded with a plurality of dosages of the microparticle and a storage container for receiving the string. The storage container has a first open end and a second opposite end. A biasing structure urges the string toward the open end of the storage container and an actuator selectively engages the string to urge a dosage of the microparticle from the open end of the storage container.

Abstract: A method is provided for fabricating a multi-layer microfluidic device on a base. A first layer is positioned on the base in a spaced relationship thereto so as to define a construction cavity therebetween. The first layer has a passageway therethrough which communicates with the construction cavity. A mask is positioned between the construction cavity and an ultraviolet source. The mask corresponds to a channel to be formed in the construction cavity. The construction cavity is filled with material and a portion of the material is polymerized within the construction cavity so as to solidify the same. The solidified material defines the channel. Thereafter, the material is flushed from the channel in the construction cavity.
