Microneedle devices are provided for controlled sampling of biological fluids in a minimally-invasive, painless, and convenient manner. The microneedle devices permit in vivo sensing or withdrawal of biological fluids from the body, particularly from or through the skin or other tissue barriers, with minimal or no damage, pain, or irritation to the tissue. The microneedle device includes one or more microneedles, preferably in a three-dimensional array, a substrate to which the microneedles are connected, and at least one collection chamber and / or sensor in communication with the microneedles. Preferred embodiments further include a means for inducing biological fluid to be drawn through the microneedles and into the collection chamber for analysis. In a preferred embodiment, this induction is accomplished by use of a pressure gradient, which can be created for example by selectively increasing the interior volume of the collection chamber, which includes an elastic or movable portion engaged to a rigid base. Preferred biological fluids for withdrawal and / or sensing include blood, lymph, interstitial fluid, and intracellular fluid. Examples of analytes in the biological fluid to be measured include glucose, cholesterol, bilirubin, creatine, metabolic enzymes, hemoglobin, heparin, clotting factors, uric acid, carcinoembryonic antigen or other tumor antigens, reproductive hormones, oxygen, pH, alcohol, tobacco metabolites, and illegal drugs.

The invention includes various prototypical amperometric biosensors for the quantification of biological substrates such as fructose, creatinine, creatine, and sarcosine, and the methods for producing these biosensors. Also included in the invention is a minaturized version of the biosensing devices. The components of these prototypical biosensors are immobilized on a self-assembled monolayer (SAM) comprising chemisorbed alkanethiols. The deposition of an amphiphilic lipid layer to these systems increases the stability and activity of the resultant biosensor and enhances the rejection of many interferents. An additional feature of the invention is the co-deposition of the components of the sensor via a novel detergent dialysis protocol. The invention features two particular biosensor systems. One embodiment involves fructose dehydrogenase as the redox / sensor enzyme and fructose as the substrate / analyte. Another embodiment involves the measurement of the substrates / analytes, creatinine, creatine and sarcosine, using sacrosine dehydrogenase as the redox / sensor enzyme, with the involvement of creatinine amidohydrolase and / or creatine amidinohydrolase in the reaction pathway.
