pH-sensitive response of a highly photoluminescent MoS nanohybrid material and its application in the nonenzymatic detection of HO.

The mechanism behind the variation in the photoluminescence (PL) of a MoS nanohybrid material with pH was investigated. Highly fluorescent MoS quantum dots dispersed across MoS nanosheets (MoS QDNS) were synthesized by a hydrothermal route in the presence of NaOH. Upon reducing the pH from 13 to 6.

MoS nanohybrid as a fluorescence sensor for highly selective detection of dopamine.

Fluorescence sensors for biologically active molecules are catching attention due to their good performance and simplicity. Herein, we report a fluorescence sensor for the selective and sensitive detection of dopamine (DA) in aqueous samples. MoS2 nanohybrid material composed of MoS2 quantum dots dispersed over MoS2 nanosheets (MoS2 QDNS) in alkaline medium was employed as the fluorescent probe.
