An enhanced formaldehyde (CH2O) sensor incorporating microsphere resonator and zinc oxide (ZnO) nanorods coated glass is reported. The microsphere resonator with a diameter of 234 mu m and the ZnO nanorods coated glass surface was fabricated using the hydrothermal synthesis method for 12 h. A signif...
