제목 Fabrication of chemiresistive gas sensor by using ligand conjugation Molybdenum Disulfides (MoS2) for lung cancer diagnosis
초록 Molybdenum disulfide (MoS2) has been favorably developed as gas sensor due to their high surface-to-volume ratio and excellent charge transport property, due to its superior properties as gas sensor as well as photodetector. According to this insight, we developed the MoS2 based chemiresistive gas sensor by forming the bulk film type of MoS2 layers. Especially, we conjugated thiolated ligands with the defects of sulfur vacancies on the MoS2 layers which were induced during exfoliation process that resulted in functionalized MoS2 sensing channels. The pristine and ligands conjugated MoS2 films showed unique sensing properties for representative VOCs (volatile organic compounds) which might lead to valuable and practical application in the breath analysis for lung cancer diagnosis.
