Carbon-Fiber Microbiosensor for Monitoring Rapid Lactate Fluctuations in Brain Tissue Using Fast-Scan Cyclic Voltammetry
Analytical Chemistry, 90(21), 12994–12999.
MeSH headings : Animals; Biosensing Techniques / methods; Carbon Fiber / chemistry; Electrochemical Techniques / instrumentation; Electrochemical Techniques / methods; Enzymes, Immobilized / chemistry; Lactic Acid / analysis; Limit of Detection; Male; Microelectrodes; Mixed Function Oxygenases / chemistry; Neostriatum / metabolism; Rats, Sprague-Dawley; Sensitivity and Specificity
TL;DR:
There is evidence that striatal lactate availability increases biphasically in response to electrical stimulation of the dopaminergic midbrain in the anesthetized rat, and this new tool for real-time detection of lactate dynamics promises to improve understanding of how lactateavailability underscores neuronal function and dysfunction.
