The dual-mode sensor allows for discrimination of mass and charge contributions for binding assays on the same sensor surface. Furthermore, we optimize the sensor geometry by investigating the influence of the fiber area to transistor channel area ratio and distance. We show that larger fiber optic tip diameters are favorable for electronic and optical signals and demonstrate the reversibility of plasmon resonance wavelength shifts after electric field application. As a proof of principle, a layer-by-layer assembly of polyelectrolytes is performed to benchmark the system against multivariable sensing platforms with planar surface plasmon resonance configurations. Furthermore, the biosensing performance is assessed using a thrombin binding assay with surface-immobilized aptamers as receptors, allowing for the detection of medically relevant thrombin concentrations."}],"volume":7,"date_created":"2022-03-06T23:01:54Z","language":[{"iso":"eng"}],"publication":"ACS Sensors","publication_status":"published","scopus_import":"1","_id":"10829","oa":1,"file":[{"success":1,"date_updated":"2022-03-07T08:15:01Z","content_type":"application/pdf","file_name":"2022_ACSSensors_Hasler.pdf","file_id":"10832","creator":"dernst","checksum":"d704af7262cd484da9bb84b7d84e2b09","access_level":"open_access","date_created":"2022-03-07T08:15:01Z","file_size":2969415,"relation":"main_file"}],"department":[{"_id":"MaIb"}],"day":"08","publisher":"American Chemical Society","article_processing_charge":"No","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","isi":1}
