She is interested in understanding biological processes such as the transport of peptides across the blood-brain barrier or diagnosis of metabolic disease.

[3] In her studies of the blood brain barrier, Lunte seeks to inform the design of next-generation pharmaceuticals or better understand neurological conditions.

She has studied combined capillary electrophoresis with microdialysis to create sensors that can monitor for multiple analytes at the same time.

Her group created a chip-based interface that can connect to the microdialysis sampling, microchip electrophoresis and the miniaturisation of the detector electronics, including the electrodes and the potentiostat.

To demonstrate this technology, Lunte has studied reactive oxygen species from macrophages and bovine brain microvessel endothelial cells.
