摘要：

A label-free platform based on integration of cantilever and photonic crystal cavity resonator is reported with both high sensitivity and ultra-high quality factor for femto-gram detection of chemicals. The proposed chemical sensor shows sharp resonant frequency with quality factor of 12800, displacement and wavelength shift is obtained as 29.9425 mu m and 7.15625 nm with chemical weight of 100 fg. The proposed sensor shows a high confinement factor of 62%, with an average sensitivity of 1.62 nm/fg manifested its promising applications for detection of various virus present in chemicals. The device shows capability to work in various fluids for chemical sensing purposes.
