Recently, molybdenum disulfide (MoS2) has allured deep research importance due to their exclusive optical, electrical and mechanical properties. Incorporation of MoS2 into logical applications it is obligatory to functionalize it with the chemical moieties. To avoid the effect of solvent and dopant on the electrode we set up a microfluidic tank over the MoS2 channel. Here we report the tailoring of electrical properties of mechanically exfoliated MoS2 by nicotine. Raman spectroscopy and electrical charge transport measurement revealed that nicotine imposes n-doping in MoS2. The threshold voltage forwarded left side from ~ 11 V to ~ 35 V, indicating n-type doping effect. Nicotine functionalization tailored the field effect mobility by a factor of ~ 6.4 without deteriorating the electrical properties of MoS2 devices.
