A new CdTe@SiO2@CdSe nanohybrid was demonstrated for the ratiometric fluorescence detection of Cd2+via the turn-on model and “ion-imprinting” technique.
In this work, silicon doped graphene quantum dots (Si-GQDs) were prepared and applied for the sensitive and selective fluorescence detection of triclosan (TCS) in combination with Ru3+ ions.
2,4-Dinitrotoluene (2,4-DNT) is a nitro aromatic compound used as a raw material for trinitrotoluene (TNT) explosive synthesis along with several other industrial applications.
A strategy for aptamer-based biosensing termed linkage inversion assembled nano-aptasensors (LIANAs) is shown to be a generally applicable approach to the sensitive and specific detection of a target molecule in turn-on fluorescence solution-based and paper-based tests.
