With a total of 6 patents, Yoon's work focuses on advancing technologies that enhance neurochemical monitoring and rare cell detection.

Latest Patents

One of Yoon's latest patents involves the microfabrication of a microdialysis probe with a nanoporous membrane. This innovative probe addresses the limitations of conventional dialysis probes, which are often too large and inflexible. Yoon's microfabricated probes are significantly smaller, measuring 45 µm thick and 180 µm wide, with a buried U-shaped channel that allows for efficient sampling. The probes have demonstrated a relative recovery rate of 2-7% at a perfusion rate of 100 nL/min for various small molecules. They were successfully tested in vivo, revealing reliable detection of neurochemicals such as dopamine and acetylcholine.

Another notable patent by Yoon is a functionalized graphene oxide system designed for detecting rare cells. This system includes a substrate and an extension coupled to the substrate, with functionalized graphene oxide disposed on the extension. The method for detecting rare cells involves introducing a sample of bodily fluid to the system, allowing for interaction with the functionalized graphene oxide.
