Kee Scholten

RESEARCH INTERESTS

• After earning a B.S. degree in Applied Physics from California Institute of Technology in June, 2009, Kee Scholten began his Ph.D. studies in the interdiscinplinary program of Applied Physics, University of Michigan in the following fall semester. He joined the Zellers Group in May of 2010.

• Kee’s research interests include microfluidic sensors for in-situ analyte detection, in particular the design and fabrication of lab-on-chip devices for point-of-care medical diagnostics and environmental monitoring. As an undergraduate Kee worked for Professor Axel Scherer on PDMS devices for non-competitive immunoassay using fluorescence and optical resonance detection.

Projects

• Kee’s current research focuses on the use of microfabricated multi-transducer arrays for discrimination of volatile-organic-compound in micro gas chromatography systems.

• Temperature modulated SnO2 nanowire vapor sensor: SnO2 nanowires are chemiresistive vapor sensors that operate on the principle of temperature modulated oxidation of volatile-organic-compounds. Recently a device consisting of mats of contact printed nanowires on top of a micro-hotplate was demonstrated as a sensitive and discriminatory vapor sensor. Previously demonstrated thiolate protected gold nanoparticle chemiresistive vapor sensors were incorporated in a study that examined the comparative diversity of a temperature modulated SnO2 nanowire array as a single material and as a component in a multi-transducer array.

• Micro-Optofluidic Ring Resonator: Optofluidic cavities have recently been demonstrated as suitable whispering-gallery mode optical resonance sensors for vapor detection. On-going work focuses on the creation of a micro-fabricated glass channel capable of supporting a circumferential optical mode that probes the response of an interior sensing layer to vapor flow.
