Abstract Graphene quantum dots (GQDs) have attracted tremendous research interest due to the unique properties associated with both graphene and dots. Here, a new application of GQDs as ideal electrode materials for supercapacitors is reported. To this end, GQDs//GQDs symmetric micro‐supercapacitor prepared using simple electro‐deposition approach, its electrochemical in aqueous electrolyte ionic liquid are systematically investigated. The results show that as‐made has superior rate...
In comparison with graphene sheets, quantum dots (GQDs) exhibit novel chemical/physical properties including nanometer-size, abundant edge defects, good electrical conductivity, high mobility, chemical inertia, stable photoluminescence and better surface grafting, making them promising for fabricating various devices. the present work, an asymmetric micro-supercapacitor, using GQDs as negative active material polyaniline (PANI) nanofibers positive material, is built first time by a simple...
Specific and sensitive detection of microRNAs continues to encounter significant challenges, especially in the development rapid efficient isothermal amplification strategies for point-of-care settings. The exponential reaction (EXPAR) has garnered attention owing its simplicity signals within a short period. However, substantial loss efficiency, difficulty distinguishing closely related homologous sequences, adapting designed templates other targets seriously hamper practical application...
Low-potential electrochemiluminescence (ECL) luminophores with excellent ECL behavior have attracted considerable interest in biological analysis. Herein, we describe the synthesis of two aggregation-induced emission (AIE)-active conjugated polymers a donor-acceptor (D-A) system via Suzuki coupling polymerization reaction. The intramolecular D-A pairs enhanced their luminescence intensity aggregate states, which was beneficial for preparation polymer dots (Pdots) as materials. P-2 Pdots...
Encapsulating a large amount of electrochemiluminescence (ECL) active molecules into one nanoparticle for single-target recognition can greatly improve the sensitivity ECL assay. This work used luminescent conjugated polymer as carrier to synthesize Ru(bpy)32+-doped dots (RuPdots). The RuPdots with an average size 20 nm and encapsulation about 1354 Ru(bpy)32+ showed enhanced emission. Using tripropylamine coreactant, resonance energy transfer from excited encapsulated was demonstrated, which...
A novel D-A conjugated polymer backbone containing silole and 9-octyl-9H-carbazole units was synthesized via Sonogashira reaction. This silole-containing (SCP) further used to prepare SCP dots with a nanoprecipitation method, which showed an electrochemiluminescence (ECL) emission at relatively low potential in aqueous solution. The strong anodic ECL could be observed +0.4 V (vs Ag/AgCl) peak value +0.78 the presence of tri-n-propylamine (TPrA) as co-reactant, came from band gap excited...
A true-color electrochemiluminescent (ECL) imaging strategy was designed for a multi-immunoassay of proteins by coupling highly efficient polymer dots (Pdots) with dual DNA amplification. The Pdots were prepared nanoprecipitation poly[(9,9-dioctylfuorenyl-2,7-diyl)-alt-co-(1,4-benzo-{2,1′,3}-thiadiazole)] in the presence poly(styrene-co-maleic anhydride) and functionalized DNA1 that hybridized black hole quencher-labeled DNA2 to self-quench ECL emission. modified Au/ITO electrode showed...
Luminescent semiconducting polymer dots (Pdots) have attracted intense attention in the field of electrochemiluminescence (ECL) due to their nontoxic features. For utilizing Pdots achieve sensitive ECL bioimaging detection, this work studied behaviors poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-(1-cyanovinylene-1,4-phenylene)] (CN-PPV) aqueous solution, which introduced an electron-withdrawing cyano group p-phenylenevinylene for enhancing luminescent efficiency. The CN-PPV could be both...
In recent years, semiconducting polymer dots (Pdots) as environmentally friendly and high-brightness electrochemiluminescence (ECL) nanoemitters have attracted intense attention in ECL biosensing imaging. However, most of the available Pdots a high excitation potential aqueous phase (>1.0 V vs Ag/AgCl), which causes poor selectivity actual sample detection. Therefore, it is particularly important to construct simple universal strategy lower trigger Pdots. This work has realized emission at...
SARS-CoV-2, especially the variant strains, is rapidly spreading around world. Rapid detection methods for virus are crucial controlling COVID-19 epidemic.

Nitrogen-doped graphene nanosheets (N-GNSs) with good morphologies were successfully synthesized by a facile solvothermal method. The result of X-ray photoelectron spectroscope (XPS) revealed that most oxygen con- taining functional groups on the surface oxide (GO) removed during reduction, and ni- trogen atoms from dimethylformamide (DMF) effectively doped into structure in form pyrrolic-N graphite-N.
