Recently, my paper “Characterization of a hybrid dielectrophoresis and immunocapture microfluidic system for cancer cell capture” was published in and featured on the cover of ELECTROPHORESIS.
This paper describes how characterization of adhesion of prostate cancer cells to immunocapture surfaces with and without dielectrophoresis (DEP) effects as a function of shear stress was performed in a Hele-Shaw flow cell. Gold interdigitated electrodes were deposited on a glass surface that was functionalized with a prostate-specific monoclonal antibody, J591; these electrodes applied an electric field gradient to attract prostate cancer cells to the immunocapture surface with positive DEP. This work demonstrates that DEP and immunocapture techniques can work synergistically to improve cancer cell capture performance, and it informs the design of future high-purity rare cell capture systems to facilitate genetic and pharmacological evaluation of cancer.
