RETRACTED: Facile synthesis of porous MoS2 nanofibers for efficient drug delivery and cancer treatment (Retracted Article)

Porous MoS2 nanofibers were synthesized by electroplating and post-annealing and applied in a responsive drug delivery system. The one-dimensional (1D) MoS2 nanofibers displayed a high specific surface area, controllable morphology, and uniform size, serving as a promising drug carrier for chemotherapy. After surface modification with polyethylene glycol (PEG) through PEGylation, the MoS2/PEG composite displayed excellent physical/chemical stability and biocompatibility. More importantly, MoS2/PEG loaded with doxorubicin (DOX) exhibited a controllable release responsive to pH and near-infrared (NIR) irradiation and demonstrated precise DOX dose release. Such remarkable anticancer effects were mainly attributed to outstanding photothermal performance and stability of porous MoS2 nanofibers. This work offered a new opportunity of employing porous MoS2 nanofibers as drug carriers for effective cancer chemotherapy.
