A proposed formaldehyde (CH2O) sensor is fabricated by exploiting evanescent wave on a glass surface coated with Zinc Oxide (ZnO) nanorods integrated with microfiber. The diameter of silica fiber is reduced by tapering using flame brushing technique to a waist diameter of 6 µm. The glass surface was...
