Sensitive detection of dopamine and quinone drugs based on the quenching of the fluorescence of carbon dots
In this work, we demonstrated that the quinone structure can quench the fluorescence of the carbon dots (CDs). The sensitive determination of dopamine (DA) was studied primarily based on this principle. DA wou...

Open AccessOptical detection of acetylcholine esterase based on CdTe quantum dots
In this study, we have constructed a simple, sensitive and rapid biosensor for detection of acetylcholine esterase (AChE) based on CdTe quantum dots (QDs). The detection limit of AChE by one-step enzyme reacti...
