Abstract: Microdialysis sampling is an essential tool for in vivo neuro-chemical monitoring. Conventional dialysis probes are over 220 ?m in diameter and have limited flexibility in design because they are made by assembly using preformed membranes. The probe size constrains spatial resolution and governs the amount of tissue damaged caused by probe insertion. To overcome these limitations, we have developed a method to microfabricate probes in Si that are 45 ?m thick 180 ?m wide. The probes contain a buried, U-shaped channel that is 30 ?m deep 60 ?m wide and terminates in ports for external connection. A 4 mm length of the probe is covered with a 5 ?m thick nanoporous membrane. The membrane was microfabricated by deep reactive ion etching through a porous aluminum oxide layer. The microfabricated probe has cross-sectional area that is 79% less than that of the smallest conventional microdialysis probes. The probes yield 2-7% relative recovery at 100 nL/min perfusion rate for a variety of small molecules.
