  • We report the use of Geometrically Enhanced Differential Immunocapture (GEDI) ╬╝devices, which employ staggered obstacle arrays functionalized with a prostate-specific antibody, to capture and analyze prostate cancer cells on chip. GE-DI ╬╝devices have been demonstrated to have high capture efficiency and purity [2] as compared similar devices found in the literature [4]. GEDI ╬╝devices have been used to isolate cells from cancer patient samples and are used herein to carry out in situ chemotherapeutic efficacy experiments with a model cell line, simulating a point-of-care diagnostics situation. In addition, we also demonstrate release of captured prostate cancer cells using desthiobiotin and standard antibody conjugation chemistry.
