About the Surface and Microanalysis Science Division
As part of the Material Measurement Laboratory at NIST the Surface and Microanalysis Science Division serves as the Nation's Reference Laboratory for chemical metrology research, standards, and data to:
- Characterize the spatial and temporal distribution of chemical species; and
- Improve the accuracy, precision, sensitivity, selectivity, and applicability of surface, interface, microanalysis, and advanced isotope measurement techniques.
The Division is organized into three groups with focused technical expertise and research in a wide range of NIST, MML and Other Agency program areas.
The Division also benefits from the contributions of a NIST Fellow and two Scientist Emeriti who, although not associated with specific groups, interact extensively with a broad cross section of the Division and with organizations internal and external to NIST.

Future Directions and Plans
Future growth for the Surface and Microanalysis Science Division is anticipated in the NIST program areas associated with Bioscience and Health, Electronics and Telecom, Public Safety and Security, and Nanotechnology.
- Bioscience and Health: The Division will expand its efforts through our NIH collaboration and a MML 3-year funding effort for site-specific chemical mapping of cells and tissue to improve biomarker discovery and clinical diagnostics. This will include developing novel super-resolution optical microscopies to probe chemical functionality at the sub-100 nm length scale
- Electronics and Telecom: In conjunction with the NIST's OMP, the Division will be developing new measurement-science paradigms for 3D atomic-scale chemical analysis relating to post CMOS technologies.
- Public Safety and Security: The Division plans to work with the DHS and NIJ to expand our program to develop calibration methods and new measurement methodologies for trace detection of illicit drugs.
- Nanotechnology: New efforts in nanotechnology are predicated on receiving funding from the 2007 congressional initiative for EHS Nano through the America Competes ACT. The Division's efforts will be directed toward research in nanomaterial characterization as it relates to EHS needs and the development of standards and standard measurement protocols.
