Abstract: A system and a method for measuring adhesion of blood cells in microfluidic channels are disclosed. The system includes a device having one or more microfluidic channels configured to adhere a plurality of diseased red blood cells (RBCs) of a blood sample on an interior surface of the one or more microfluidic channels. Further, the system includes at least one imager configured to generate one or more digital holography images or videos of the plurality of diseased RBCs adhered to the interior surface of the one or more microfluidic channels. Further, at least one processor is operationally coupled to the at least one imager and configured to receive the one or more digital holography images or videos and analyze the generated one or more digital holography images or videos to quantify adhesion of the plurality of diseased RBCs to the interior surface of the one or more microfluidic channels.

Abstract: A system and a method for measuring deformability of red blood cells in microfluidic channels are disclosed. The system comprises one or more devices having one or more microfluidic channels with at least one cross-sectional dimension and configured to allow deformation of red blood cells of a blood sample to flow through the one or more microfluidic channels. Further, at least one imager is configured to generate a sequence of digital holography images or videos of the red blood cells of the blood sample transiting through the one or more microfluidic channels. Further, the system includes at least one processor that is operationally coupled to the at least one imager. The at least one processor is configured to analyze the generated sequence of digital holography images or videos to quantify and characterize deformability of the red blood cells within the one or more microfluidic channels.

Abstract: A method, system, and computer program product for determining calibration parameters for controlling the intensity of a laser diode are provided. An example method may include determining a slope representing a relation of a change in a photodiode output value to an input current transmitted to the laser diode. In the example method, the photodiode output value is received from a monitoring photodiode positioned to receive light from the laser diode, wherein the photodiode output value corresponds to the intensity of light generated by the laser diode and received at the monitoring photodiode. The example method further includes selecting an operating photodiode output value based at least in part on the slope, wherein the operating photodiode output value corresponds to a target photodiode current at the monitoring photodiode during operation.
