Orthogonal Measurements

Ongoing

Definitions: Orthogonal measurements: Measurements that use different physical principles to measure the same property of the same sample with the goal of minimizing method-specific biases and interferences. Complementary measurements: Measurements that corroborate each other to support the same

Quantitative, Traceable Determination of Cell Viability Using Absorbance Microscopy

Ongoing

The current gold standard for cell viability measurements is the trypan blue assay. Trypan blue dye enters dead cells that have a ruptured membrane. As a result, the dead cells are stained blue. Live cells with an intact membrane, on the other hand, do not absorb the dye molecules and remain

Fluorescence Microscopy Benchmarking: Overview

Completed

A challenge in using microscopy is how to compare and validate data from different instruments, and how to determine that the microscope performance today is the same as yesterday. NIST is developing a practical, automated approach to implementing performance benchmarking methods that will

Development of Biomarker-based Systems for Cancer Detection and Therapy

Completed

Intended impact Although significant progress has been made in both the understanding and treatment of cancer during the last thirty years, it remains the second leading cause of death in the US. The cancer community has set a goal to eliminate cancer-related suffering and death by 2015. To achieve
