Potential-modulated electrochemiluminescence of a tris(2,2′-bipyridine)ruthenium(II) / lidocaine system under 430 kHz ultrasound irradiation

In Situ Ultrasound Irradiation for Regulating the Electrochemiluminescence Intensity and Layer

“…Although the increase in mass transfer rate reduced the diffusion layer thickness in many electrochemical studies, as far as we know, imaging the ECL layer under in situ US has not been reported before. Therefore, to directly observe the change of the ECL layer under US, a homemade microscope was built to record ECL images of the chitosan film on the conductive side of the ITO electrode.…”

Boosting the electrochemiluminescence of luminol by high-intensity focused ultrasound pretreatment combined with 1T/2H MoS2 catalysis to construct a sensitive sensing platform

“…For example, it has been proved that ultrasound irradiation could markedly enhance the ECL emission of arylacetate [22] . In addition, ECL response of Ru(bpy) 3 2+ /lidocaine system was also obviously improved with ultrasound irradiation [23] . Inspired by the above, HIFU pretreatment, as a non-invasive pretreatment means, was introduced into the lumino-O 2 ECL system to promote the conversion of dissolved O 2 to ROS in situ and enhance ECL signal firstly in our group [24] .…”

Ultrasound-pretreatment combined with Ti3C2-TiO2-AuNPs enhancing the electrogenerated chemiluminescence of the air-saturated luminol for exosomes detection

“…In the process of bubble shrinkage, the internal gas is compressed, resulting in the decomposition of water molecules and O 2 to generate ROS, such as O 2 –• , 1 O 2 , H 2 O 2 and so on [18] , [19] . So far, only a few papers on the application of ultrasound in ECL have been reported [20] , [21] . Our research group has done the related work in the field of ECL sensing, especially in improving selectivity and sensitivity by using nanomaterials [3] , [5] .…”
