“…Binding of low-density lipoprotein with apoB-100 resulted in an increased impedance of electrode and inhibited reaction between coreactant and electrode, leading to quenched ECL emission. Immunorecognition-induced protein binding combined with ECL from QDs provides a versatile and sensitive immunoassay format. ,,,,,− Similarly, aptamer-based protein recognition has also been explored for thrombin detection based on impedance increase-induced ECL quenching. , …”

“…Some printing techniques, such as electrodeposition, may enable the transfer of thin films of metal nanoparticles [ 61 ] or nanowires [ 62 ] to a substrate, via an electric field. Printing thin films of metals can be utilized to create circuits that may be an integral part of a biosensor, as well as for some immunoassays or microarrays [ 63 , 64 ]. Electrodeposition has even been applied for printing thin films of biological material such as proteins, enzymes, nucleic acids, polysaccharides and bacterial cells [ 65 , 66 , 67 ].…”

Future biosensing applications will require high performance, including real-time monitoring of physiological events, incorporation of biosensors into feedback-based devices, detection of toxins, and advanced diagnostics. Such functionality will necessitate biosensors with increased sensitivity, specificity, and throughput, as well as the ability to simultaneously detect multiple analytes. While these demands have yet to be fully realized, recent advances in biofabrication may allow sensors to achieve the high spatial sensitivity required, and bring us closer to achieving devices with these capabilities. To this end, we review recent advances in biofabrication techniques that may enable cutting-edge biosensors. In particular, we focus on bioprinting techniques (e.g., microcontact printing, inkjet printing, and laser direct-write) that may prove pivotal to biosensor fabrication and scaling. Recent biosensors have employed these fabrication techniques with success, and further development may enable higher performance, including multiplexing multiple analytes or cell types within a single biosensor. We also review recent advances in 3D bioprinting, and explore their potential to create biosensors with live cells encapsulated in 3D microenvironments. Such advances in biofabrication will expand biosensor utility and availability, with impact realized in many interdisciplinary fields, as well as in the clinic.

“…If an analyte (Ag) exists in the solution, the analyte binds to the Ab labelled with ECL, and then the ECL signal will decrease. Generally, the decrease of the ECL signal is proportional to the concentration of the analyte [6,11].…”

Electrogenerated Chemiluminescence for Immunoassay Applications

Electrogenerated chemiluminescence (ECL) has recently become one of the most prominent and well-established transducers for immunoassay techniques. ECL relates a luminophore concentration in solution with the emission of light triggered by an electrochemical stimulus. ECL immunoassay (ECLIA) performance depends on the parameters of its light generation, including the luminophore, the species that emit light called labels in ECLIA; co-reactants, which are added reagents that support the luminophore to undergo the excited state; electrodes, which are the place for the ECL reactions to take place; and the format of the immunoassay. This review discusses the behaviour of ECLIA parameters, the required instrumentations, and some important examples of detections based on ECLIA.
