Two people working in the Cleanroom

Mantei Center Cleanroom

The Mantei Center Cleanroom is a central fabrication, processing, and characterization center intended to be used by a diverse campus-wide research community. The more than 8000 square foot facility includes areas of class 10, 100, 1000, and 10,000 cleanroom spaces. It includes lithography, deposition, etching, oxidation, and electrical and optical characterization tools.

The Cleanroom is a university facility that encourages use from all colleges and departments on campus as well as other academic and industrial users. To gain access to the facility one needs to complete the ERC Cleanroom safety course as well as the OSHA online Hazardous Communications training courses. The completion of these and possessing appropriate personal protective equipment will allow access to the laboratory facility. Additional training is required to use a majority of the facility equipment.

Ryan J White

Professor and Ohio Eminent Scholar, Unit Head - Chemistry, A&S College of Arts and Sciences



My research and teaching interests lie at the intersection of nanoscience, electrochemistry and the biological interface. The research interests in our group focus on the development of new (bio)analytical methods to probe chemical and biological systems with unprecedented spatial and temporal resolutions afforded by working at the nanoscale. The scope of this research is quite broad, ranging from studies of fundamental chemical and biological phenomena to the development of applied sensor technologies. As such, students in the group can expect to gain valuable interdisciplinary laboratory experience.
Ryan J. White is Professor and Ohio Eminent Scholar in the Department of Chemistry with a complimenrary joint appointment in the Department of Electrical and Computer Engineering. He has served as Head of Chemistry since Fall 2022. Ryan received his bachelor’s degree in chemistry from the University of North Carolina (2003) and earned a Ph.D. in chemistry from the University of Utah (2007). He was an NIH NRSA Postdoctoral Fellow at the University of California Santa Barbara. Ryan started his academic career as an assistant professor in Chemistry and Biochemistry at UMBC in 2011, and was promoted to associate professor with tenure in 2016. Ryan joined UC in the fall of 2017. Ryan is also the recipient of the Royce W. Murray Young Investigator Award from the Society for Electroanalytical Chemistry.
