Recently, WS₂NM-based nanocarriers have been developed in drug delivery systems, which also promote their application in tissue engineering. Due to the electrical properties of WS₂, researchers have designed tungsten disulfide nanomaterials (WS₂NM)-based electro-responsive drug delivery systems. Conventional drug delivery systems, such as oral and injectable, require higher concentrations of drugs to see therapeutic effects, and administering too much of the drug can lead to side effects in some patients.

With the development of nanotechnology, tungsten disulfide nanomaterials (WS₂NM) have been a new choice for optical biosensors. Researchers reported the use of a simple method to create a hybrid material consisting of WS₂ nanosheets and hydroxylated MWCNTs (WS₂/MWCNTs-OH). The substrate was screen-printed carbon electrodes (SPCE), which has the advantage of requiring minimal cost and being disposable and energy efficient. Modification with WS₂/MWCNTs-OH composites improved the rate of sensitive and selective behavior.

The high atomic number and near-infrared absorption of tungsten disulfide quantum dots (WS₂-QDs) (3 nm and 28 nm) of tungsten disulfide nanomaterials enable their synthesis as enhancers for X-ray computed tomography (CT)/photoacoustic imaging (PA), boosting their applications in bioimaging and radiotherapy.

Tungsten disulfide nanomaterials can be successfully used in biosensors and nanomedicine, such as observation of DNA hybridization, enzymes, and proteins, as well as environmental contamination and medical diagnostics. For a long time, electrochemical biosensors, such as semiconductors and screen-printed electrodes, have been used for various applications in numerous fields.
