With my background in medicine, microdevice engineering, and nanotechnology, my strengths lie in developing novel solutions to urgent problems in medicine and cancer research. Having developed a diagnostic microfluidic device at Caltech and initiated a clinical trial to test the device on glioblastoma patients at UCLA, I?m particlularly interested in moving promising technologies past the proof-of-concept phase and into the clinic. My career goals are to continue to work at the interface of medicine and technology as an academic scientist, engineering new wearable and implantable technologies for earlier cancer detection and continuous monitoring.

  • A self-powered, one-step chip for rapid, quantitative and multiplexed detection of proteins from pinpricks of whole blood LAB ON A CHIP Wang, J., Ahmad, H., Ma, C., Shi, Q., Vermesh, O., Vermesh, U., Heath, J. 2010; 10 (22): 3157-3162


    We describe an automated, self-powered chip based on lateral flow immunoassay for rapid, quantitative, and multiplex protein detection from pinpricks of whole blood. The device incorporates on-chip purification of blood plasma by employing inertial forces to focus blood cells away from the assay surface, where plasma proteins are captured and detected on antibody "barcode" arrays. Power is supplied from the capillary action of a piece of adsorbent paper, and sequentially drives, over a 40 minute period, the four steps required to capture serum proteins and then develop a multiplex immunoassay. An 11 protein panel is assayed from whole blood, with high sensitivity and high reproducibility. This inexpensive, self-contained, and easy to operate chip provides a useful platform for point-of-care diagnoses, particularly in resource-limited settings.

  • Fast Nonlinear Ion Transport via Field-induced Hydrodynamic Slip in Sub-20-nm Hydrophilic Nanofluidic Transistors NANO LETTERS Vermesh, U., Choi, J. W., Vermesh, O., Fan, R., Nagarah, J., Heath, J. R. 2009; 9 (4): 1315-1319


    Electrolyte transport through an array of 20 nm wide, 20 microm long SiO(2) nanofluidic transistors is described. At sufficiently low ionic strength, the Debye screening length exceeds the channel width, and ion transport is limited by the negatively charged channel surfaces. At source-drain biases >5 V, the current exhibits a sharp, nonlinear increase, with a 20-50-fold conductance enhancement. This behavior is attributed to a breakdown of the zero-slip condition. Implications for energy conversion devices are discussed.

  • Self-powered microfluidic chips for multiplexed protein assays from whole blood LAB ON A CHIP Qin, L., Vermesh, O., Shi, Q., Heath, J. R. 2009; 9 (14): 2016-2020


    We report herein on a self-powered, self-contained microfluidic-based chip designed to separate plasma from whole blood, and then execute an assay of a multiplexed panel of plasma biomarker proteins. The power source is based upon a chemical reaction that is catalytically triggered by the push of a button on the chip. We demonstrate assays of a dozen blood-based protein biomarkers using this automated, self-contained device. This platform can potentially permit high throughput, accurate, multiplexed blood diagnostic measurements in remote locations and by minimally trained individuals.

  • Integrated barcode chips for rapid, multiplexed analysis of proteins in microliter quantities of blood NATURE BIOTECHNOLOGY Fan, R., Vermesh, O., Srivastava, A., Yen, B. K., Qin, L., Ahmad, H., Kwong, G. A., Liu, C., Gould, J., Hood, L., Heath, J. R. 2008; 26 (12): 1373-1378


    As the tissue that contains the largest representation of the human proteome, blood is the most important fluid for clinical diagnostics. However, although changes of plasma protein profiles reflect physiological or pathological conditions associated with many human diseases, only a handful of plasma proteins are routinely used in clinical tests. Reasons for this include the intrinsic complexity of the plasma proteome, the heterogeneity of human diseases and the rapid degradation of proteins in sampled blood. We report an integrated microfluidic system, the integrated blood barcode chip that can sensitively sample a large panel of protein biomarkers over broad concentration ranges and within 10 min of sample collection. It enables on-chip blood separation and rapid measurement of a panel of plasma proteins from quantities of whole blood as small as those obtained by a finger prick. Our device holds potential for inexpensive, noninvasive and informative clinical diagnoses, particularly in point-of-care settings.
