Electrochemiluminescence (electrogenerated chemiluminescence, ECL), which involves light emission from excited states of electrochemically generated species at the electrode surface, is widely applied for chemical analysis. Integrating the advantages of outstanding selectivity from biological recognition and the high sensitivity of ECL signaling, ECL biosensors are powerful for ultrasensitive bio‐checkups and quantification, in which luminol is adopted as an important luminophore. Nanomaterials have been introduced into ECL biosensors, which enlarge the applicable pH range and improve analytical performances, with successful applications in clinical events. In particular, this Minireview will focus on new progresses related to luminol‐based biosensors and their applications in clinical diagnosis, with emphasis on nanomaterials being employed as the improver.

“…A number of sophisticated methods such as flame atomic absorption [6], electrochemiluminescence [7], thin film sequential injection [8], graphite furnaceatomic electrochemiluminescence absorption spectrometry (GF-AAS) [9], electrothermalatomic absorption spectrometry [10], and differential pulse anodic stripping voltammetry [11] have been reported for determination of cobalt. These methods are time consuming, involving sample manipulation, and are relatively expensive and require large infrastructure back-up.…”

“…In particular, these methods, which can be conveniently and easily monitored by the naked eye, are appropriate for real-time monitoring of target heavy metal ions and potential application in on-site detection owing to their simplicity and portability [ 32 ]. To date, several approaches are reported, such as chemiluminescence [ 33 ], electro chemiluminescence [ 34 ], and fluorescein probes [ 35 , 36 , 37 ]. In particular, a number of colorimetric sensors based on functional gold and silver nanoparticles (NPs) have been reported [ 38 , 39 , 40 ].…”

A simple, rapid, and convenient colorimetric chemosensor of a specific target toward the end user is still required for on-site detection and real-time monitoring applications. In this study, we developed a rapid in situ colorimetric assay for cobalt detection using the naked eye. Interestingly, a yellow to light orange visual color transition was observed within 3 s when a Chrysoidine G (CG) chemosensor was exposed to cobalt. Surprisingly, the CG chemosensor had great selectivity toward cobalt without any interference of other metal ions. Under optimized conditions, a lower detection limit of 0.1 ppm via a spectrophotometer and a visual detection limit of 2 ppm with a linear range from 0.4 to 1 ppm (R2 = 0.97) were determined. Moreover, the CG chemosensor is reversible and maintains its functionality after treatment with chelating agents. In conclusion, we show the superior capabilities of the CG chemosensor, which has the potential to provide extremely facile handling, high sensitivity, and a fast response time for applications of on-site detection to real-time cobalt monitoring for the general public.
