Special Issue Information

Dear Colleagues,

Among various electroanalytical sensing methods, the electrochemiluminescence (ECL) sensor has attracted widespread attention due to its merits of high sensitivity and excellent analytical performance. Notably, with the rapid development of nanotechnology, different types of ECL sensors, especially ECL biosensors, have been skillfully fabricated and have shown excellent performance, which mean that ECL biosensors can compatibly address analytical issues in various fields, such as analytical chemistry, applied chemistry, environmental science and technology, agriculture technology, food analysis, medical diagnosis, etc. Innumerable analytes, such as heavy metal ions, mycotoxins, environmental estrogens, antibiotics, pesticide residues, veterinary drug residues, tumor markers, virus, etc., could be detected in trace or ultra trace quantities by means of ECL biosensors. All these developments and applications of ECL biosensors are mainly attributed to the applications of novel and excellent functional nanomaterials.

This Special Issue of Biosensors aims to provide a platform for the publication of original high-quality research papers covering the most recent advances as well as comprehensive reviews in the field of ECL biosensors fabricated with the development of nanotechnology and nanomaterials. Contributions on various kinds of ECL (bio)sensors based on (but not limited to) nanomaterials, such as porous nanomaterials, MOFs nanomaterials, biomass-based nanomaterials, QDs, 2D nanomaterials, nanoarray, etc., are all welcome.

Metal-organic frameworks (MOFs) are often used as carriers in the preparation of electrochemiluminescent (ECL) materials, and ECL materials stabilized in the aqueous phase can be prepared by encapsulating chromophores inside MOFs by an in situ growth method. In this study, nanocomposites MIL-88B(Fe)-NH2@Ru(py)32+ with excellent ECL response were prepared by encapsulating Tris(2,2′-bipyridine)ruthenium dichloride (Ru(py)32+) inside MIL-88B(Fe)-NH2 using the one-step hydrothermal method. MIL-88B(Fe)-NH2 possesses abundant amino groups, which can accelerate the catalytic activation process of K2S2O8, and its abundant pores are also conducive to the enhancement of the transmission rate of co-reactant agents, ions, and electrons, which effectively improves the ECL efficiency. In order to obtain more excellent ECL signals, we prepared aminated biochar (NH2-biochar) using Pu-erh tea dregs as precursor and loaded gold nanoparticles (Au NPs) on its surface as substrate material for modified electrodes. Both NH2-biochar and Au NPs can also be used as a co-reactant promoter to catalyze the activation process of co-reactant K2S2O8. Therefore, a sandwich-type ECL immunosensor was prepared based on a dual signal-enhanced strategy for the highly sensitive and selective detection of aflatoxin B1 (AFB1). Under the optimal experimental conditions, the sensitive detection of AFB1 was achieved in the range of 1 pg·mL−1~100 ng·mL−1 with a detection limit of 209 fg·mL−1. The proposed dual signal-enhanced ECL immunosensor can provide a simple, convenient, and efficient method for the sensitive detection of AFB1 in food and agricultural products. Full article
