Sensors: 6‐Mercaptopurine‐Induced Fluorescence Quenching of Monolayer MoS₂ Nanodots: Applications to Glutathione Sensing, Cellular Imaging, and Glutathione‐Stimulated Drug Delivery (Adv. Funct. Mater. 41/2017)

Abstract

In article number https://doi.org/10.1002/adfm.201702452, Wei‐Lung Tseng and co‐workers describe the modification of monolayer MoS2 nanodots (M‐MoS2 NDs) with 6‐mercaptopurine and thiolated doxorubicin through the attachment of the thiol group on existing sulfur vacancy sites. The formed 6‐mercaptopurine/M‐MoS2 NDs are used for sensing glutathione, while the thiolated doxorubicin/M‐MoS2 NDs are implemented for glutathione‐stimulated drug delivery.

2D Materials and Primary Human Dendritic Cells: A Comparative Cytotoxicity Study

“…In the case of MoS 2 , Raman spectrum displayed two characteristic bands at 378.4 and 404.1 cm −1 , corresponding to the peaks of the in‐plane E 1 2g vibration and out‐of‐plane A 1g vibration modes of the hexagonal MoS 2 crystal, respectively, confirming the good quality of 2D MoS 2 nanosheets (Figure 1I). [ 44 ] The distance between the bands E 1 2g and A 1 1g can be also used to calculate the average number of layers, which corresponds to ≈5 to 6 layers for our exfoliated material, [ 45 ] as observed by AFM (Figure S3, Supporting Information).…”
