A bioforce probe consisting of a swollen red blood cell (functioning as a spring with spring constant of 100pN/student submitted image, transcription available belowm firmly held in place by micropipette suction and a latex microsphere firmly attached to the surface of the red blood cell. The bioforce probe was used to measure the point force applied on a neutrophil being pulled away by another micropipette. During one of the repeating test cycles, the neutrophil was controlled to move away at 2student submitted image, transcription available belowm/s, while the microsphere was found to adhere to the neutrophil and move at 1.5student submitted image, transcription available belowm/s. Determine the stiffness (in pN/student submitted image, transcription available belowm) of the neutrophil based on the testing
