TL;DR
A straightforward, rapid, and highly sensitive biosensor has been developed for the detection of doxorubicin (DOX) in human serum samples, achieving a low detection limit of 0.029 µM.
Sensitive and accurate monitoring of arginase activity is significant for clinical diagnosis. Herein, a dual-enhanced aggregation-induced electrochemiluminescence (ECL) biosensor was constructed based on triple-ligand-protected gold nanoclusters (AuNCs), sequentially coating 6-aza-2-thiothymine-capped AuNCs with L-argi...
The endogenous hydrogen sulfide (H2S) is a vital signaling molecule and plays an important role in the physiological processes. Its abnormal level can cause various detrimental effects. Thus, there is a bourgeoning need to develop facile and sensitive methods for detecting H2S in various biological samples. Herein, a f...
Herein, silver nanoclusters (FO-Ag NCs) were synthesized using folic acid and O-phenylenediamine as ligands, with an emission at 578 nm when excited at 410 nm. The FO-Ag NCs achieved multivariate determination for Hg2+ and bovine serum albumin (BSA) via two strategies. Initially, Hg2+ quenched the emission, while BSA e...
Gold nanostructures with branched morphologies exhibit strong plasmonic properties, enabling advanced biosensing and biochemical applications. Here, we report a rapid and scalable synthesis of gold nanoflowers (AuNFs) using modified benzenethiols as both reducing and capping agents. Benzenethiols bearing electron-donat...
Kanamycin (Kana) residues released into aquatic environments due to its extensive use have raised increasing concerns because of their potential risks to ecosystems and human health. In this work, we report a label-free split aptamer-modified gold nanoflower (AuNF)-based aptasensing platform with colorimetric and elect...
The sensitive and selective detection of nucleoside biomarkers is crucial for the early diagnosis and monitoring of various physiological and pathological conditions. In this work, polyaniline (PANI)/MXene quantum dot (MQD) nanohybrids were developed as an electrochemical sensing platform for the detection of the bioma...
