Method & Evidence

AimCan photolithographic mimics of bacteria be used to fabricate biomimetic surface imprinted polymer (SIP) biosensors that exhibit enhanced E. coli capture capabilities?
MethodExperimental fabrication and characterization
ProcedureA master stamp with photolithographic mimics of E. coli was created. This stamp was used to create biomimetic SIPs by imprinting the polymer matrix. The E. coli-capturing ability of these SIPs was then tested and compared to non-imprinted polymers and SIPs with non-matching cavity geometries using atomic force microscopy (AFM) and scanning electron microscopy (SEM). The performance of SIPs integrated with interdigitated electrodes and QCM chips for E. coli detection was evaluated using electrochemical impedance spectroscopy (EIS) and QCM with dissipation monitoring (QCM-D).
