The earliest work described uses time series analysis of a live trout cardiovascular system to examine the relationship between venous pressure and cardiac output. This led to experimental work on red blood cell (RBC) DC electrokinetic transport in a capillary system and uncovered ionic limitations inherent in the small volumes of fluid used in microdevices. Further exploration of RBC characteristics revealed a unique polarization phenomena existing in a non-uniform AC field microdevice.

520 $a The earliest work described uses time series analysis of a live trout cardiovascular system to examine the relationship between venous pressure and cardiac output. This led to experimental work on red blood cell (RBC) DC electrokinetic transport in a capillary system and uncovered ionic limitations inherent in the small volumes of fluid used in microdevices. Further exploration of RBC characteristics revealed a unique polarization phenomena existing in a non-uniform AC field microdevice.
520 $a The interactions between venous pressure and cardiac output were examined by periodically infusing and withdrawing blood into a live trout's cardiovascular system. Time series analysis and the Hilbert transform were used to extract from raw frequency response data information that reveals that (a) cardiac output is determined by venous pressures behind the heart and (b) heart rate and stroke volume adapt through regulatory mechanisms to make minor adjustments to cardiac output. This could potentially impact our understanding of hypertension, a disease characterized by high blood pressures.
520 $a In the second phase of this research, red blood cell movement in capillaries was examined using video microscopy. Flow direction anomalies were observed experimentally and explained by the development of a pH gradient between the cathode well and the anode well due to electrode electrolysis reactions. The development of the pH gradient inside the 20 micron capillary was also imaged with a fluorescent pH indicator, Rhodol Green(TM) carboxylic acid.
520 $a A new electrokinetic technique known as dielectrophoresis (AC, non-uniform field) was utilized to further probe red blood cell characteristics. This work revealed an unexplored repulsion mechanism due to polarization of the red blood cell's Debye layer interacting with the electrode's polarized Debye layer. Cell-cell interactions also play a key role in suspension behaviors within the dielectrophoretic microdevice.
520 $a DC and AC electrokinetic research of red blood cells may lead to the development of medical diagnostic kits capable of (a) screening for a person's blood/drug compatibility before systemic administration of the medication, (b) screening blood for toxin exposure, or (c) cellular separations. Collectively, this work has explored macro and microscopic characteristics of blood ranging from the entire cardiovascular system to cellular interactions with electrically influenced surfaces.
