“…Similarly, Zhu et al reported a RET strategy based on N-doped GDs/Ni(OH) 2 with a three-dimensional hierarchical and stacked lamellar structure as the ECL donor and Fe 3 O 4 @MnO 2 composites with a wide absorption range as the ECL acceptor. 151 After the sandwich immunoassay via a specific antigen-antibody interaction, the ECL intensity of N-doped GDs on the electrode surface was quenched and the variable can be used to realize reliable detection of prostate protein antigen in real serum samples with good recoveries.…”

“…Electrochemiluminescence resonance energy transfer (ECL-RET) is a spectroscopy method that is caused by the energy transfer between ECL donor and acceptor at the nanometer-scale. − At large distances, typically over 12 nm, the ECL-RET using the SPR structures as ECL acceptor could increase the emission intensity of the ECL donor, which was reported as “plasmon-enhanced ECL” in the previous literature. , At small distances, typically less than 10 nm, the ECL-RET mainly manifested as the quenching to the ECL signal. , Because of the unique advantages of ECL-RET, such as no interference from the scattering light, low cost, and high sensitivity, ECL-RET has attracted growing attention in the detection of proteins, DNA, and small molecules. − However, challenges exist in the system, including the electrochemical instability of acceptor and the difficulty to find a well-overlapped ECL donor–acceptor pair. In recent decades, plasmonic nanoparticles (Au, Ag, and Pt nanoparticles) have been widely investigated as the acceptor in the ECL-RET system for their easy preparation and favorable electrochemical stability. , As a typical plasmonic nanostructure, gold nanospheres could exhibit high energy transfer efficiency to the ECL donor, for example, semiconductor nanocrystals, in the ECL-RET biosensors due to their strong plasmon absorption .…”

This paper describes an electrochemiluminescence resonance energy transfer (ECL-RET) system using Ru(bpy)-doped silica nanoparticles (RuSi NPs) as the ECL donor and hollow Au nanocages as the ECL acceptor. Tetrahedron DNA (TD) was used to construct the biosensing interface and control the distance (4.8 nm) between the ECL donor-acceptor pairs. The surface plasmon resonance (SPR) nanostructures, Au nanocages were assembled via the hairpin based sandwich assay. Due to the well overlap between the plasmon absorption spectrum of Au nanocages (628 nm) and the ECL emission spectrum of RuSi NPs (620 nm), high efficient energy transfer could occur. Subsequent cyclic DNA amplification further increased the binding amount of Au nanocages. Since the ECL inhibition is closely related with the binding amount of Au nanocages, a general "signal-off" ECL bioassay could thus be tailored with high sensitivity. At the optimized conditions, this ECL-RET system performed well with great stability and repeatability for nucleic acid detection in the range from 1.0 fM to 10 pM. This work manifested the great promise of hollow Au nanocages for an ECL-RET biosensor that to the best of our knowledge has not been reported. We believe that it could inspire more interest in the design and development of numerous other SPR nanostructures for advanced ECL-RET biosensors.

“…In a similar fashion, a label free method was developed based on silver nanoparticles doped with Pb(II) incorporated into a metal cyclodextrin organic framework with comparable limits of detection [63]. Quantum dots showed to be able to undergo emission under ECL settings and in consequence they have been applied to the construction of ECL PSA biosensors [64,65].…”

Prostate cancer has a high incidence in men and remains the second cause of mortality due to cancer worldwide. As the development of the disease is greatly correlated to age, the identification of novel detection methods reliable, efficient, and cost effective is a matter of significant importance in the ageing population of western societies. The detection of the prostate specific antigen (PSA) in blood samples has been the preferred method for the detection and monitoring of prostate cancer over the past decades. Despite the indications against its use in massive population screening, PSA still remains the best studied biomarker for prostate cancer and the detection of its different forms and incorporation in multiplexed designs with other biomarkers still remains a highly valuable indicator in the theranostics of prostate cancer. The latest developments in the use of nanomaterials towards the construction of PSA biosensors are reviewed hereby. The incorporation of gold nanoparticles, silica nanoparticles and graphene nanostructures to biosensing devices has represented a big leap forward in terms of sensitivity, stability and miniaturization. Both electrochemical and optical detection methods for the detection of PSA will be reviewed herein.
