Three‐Dimensional Graphene Network Decorated with Bimetallic Cerium/Copper Oxide Nanoparticles for Non‐Enzymatic Diagnosis of Phenylketonuria

“…This behavior catalyzed the electron transfer of L-Phe in the solution. [36] The catalytic effect of rare earth oxide NPs such as Sm 2 O 3 , [37] Gd 2 O 3 , [38] and CeO 2 [39][40] on current has been shown in previous studies.…”

Recent trends and advancements in electrochemiluminescence biosensors for human virus detection

“…Numerous ECL luminophores were synthesized in the past years, and several organic, inorganic, and nanomaterial systems can produce ECL [ 22 ]. Nevertheless, among the different emitting species commonly utilized in ECL biosensors, ruthenium complexes [ [23] , [24] , [25] , [26] , [27] ] and luminol [ [28] , [29] , [30] , [31] , [32] , [33] ] derivatives are the most popular ones employed due to their high solubility in an aqueous medium and the ability to use at a physiological pH in biological samples and also viral detection.…”

Development of sandwich electrochemiluminescence immunosensor for COVID-19 diagnosis by SARS-CoV-2 spike protein detection based on Au@BSA-luminol nanocomposites

“…Electrochemiluminescence (ECL)-based sensors are classified as one of electrochemical sensors featuring good sensitivity as well as stability. ECL technology has become more popular in recent years as a strong analytical technique for the detection of biomolecules in clinical, environmental, and industrial settings [5] , [6] , [7] . The ECL method has also been used in the analysis of disease-related biomarkers.…”
