This work presents the use of a flow injection capacitive immunosensor to detect staphylococcal enterotoxin A (SEA). The study was based on the direct detection of a capacitance change due to the(More)
A label-free immunosensor based on a modified gold electrode incorporated with silver (Ag) nanoparticles (NPs) to enhance the capacitive response to microcystin-LR (MCLR) has been developed.(More)
A procedure was developed for the covalent coupling of anti-alpha-fetoprotein antibody (anti-AFP) to a gold surface modified with a self-assembled monolayer (SAM) of thiourea (TU). The performance of(More)
This work presents the results of the use of flow injection surface plasmon resonance and impedimetric affinity biosensors for detecting and enumerating total bacteria based on the binding between E.(More)
This study compared the responses of three enzyme reactors containing urease immobilized on three types of solid support, controlled pore glass (CPG), silica gel and Poraver. The evaluation of each(More)
This paper presents a comparison between surface plasmon resonance (SPR) and capacitive immunosensors for a flow injection label-free detection of cancer antigen 125 (CA 125) in human serum. Anti-CA(More)
