The present invention relates to various methods of sensitizing and modifying nanosensor platforms. In one embodiment, the present invention provides a method of increasing sensitivity by inhibiting oxidation of one or more 1,4-hydroquinone (HQ) molecules, functionalizing the nanosensor by using one or more diazonium molecules, creating one or more oxidized carbon groups on the nanosensor, and/or depositing one or more metal clusters on the nanosensor.

surface of indium oxide nanowire (In2O3 NW) mat devices is presented. A self-assembled monolayer (SAM) of 4-(1,4-dihydroxybenzene)butyl phosphonic acid (HQ-PA) was generated on an indium tin oxide (ITO)-coated glass and In2O3 NWs surface. The chemical steps required for surface derivatization were optimized on an ITO surface prior to modifying the In2O3 NWs. The hydroquinone group contained in the HQ-PA
