Abstract: This paper presents a new poly(ethylene glycol) (PEG) hydrogel based microchip with patterned nanoporous aluminum oxide membrane (AOM) for bacteria fast patterning and detection with low frequency impedance spectrum. The PEG hydrogel micropatterns on the saline-modified nanoporous alumina surface created controlled spatial distribution of hydrophobic and hydrophilic regions. For bacteria patterning and sensing purpose, 20 ?? 20 microwell arrays were fabricated. These microwell arrays were composed of hydrophilic PEG sidewalls and hydrophobic silane-modified AOM bottom. In the surrounded areas of the microwells where PEG was UV polymerized, solid hydrogel was covalently bonded with silane-modified membrane and this close covering prevented electrolyte flow through the portions underneath the membrane. Anti-E. coli antibody was added and wa
