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

Comparing the Biological Responses of Photoluminescent Silicon Nanoparticles with Silicon Micron-sized Particles

Completed

Intended Impact Technology is now available to produce nanoparticles of uniform size and shape which may allow their use in a wide range of applications from drug delivery to water purification. The high surface area to volume ratio of nanoparticles makes them particularly good catalysts as well as

Live Cell Imaging of Induced Pluripotent Stem Cell Populations

Ongoing

As part of our program in Cell Biology , our live cell image program supports the advancement of induced pluripotent stem cell (iPSC) technology in three ways: 1) Identification of process control measurements: A critical component to the translation of iPSCs into therapeutic applications is to
