Measurement of metabolism by colorimetric assay of cells grown on photoresist. HeLa, RBL or 3T3 cells were cultured on glass (squares), 1002F photoresist (circles), or 1002F photoresist with 1% maghemite nanoparticles (triangles) for varying times. Shown on the “y” axis is the absorbance of the orange formazon product produced by metabolically active cells. Error bars represent the standard deviation of four measurements.
