we demonstrate effective and robust surface functionalization of oxide surface with phosphonic acid and demonstrate their applications in biosensing with plasmon-enhanced infrared spectroscopy. The Al metamaterials and ITO nanorod arrays are promising for novel and ultrasensitive infrared molecular sensing applications
