Optical sensors are devices that transform the interaction between medium and analyte to optical signal. Optical interference is a technique that has been widely applied in optical sensors, which is label-free, fast and non-invasive. Light reflected from the top and bottom surfaces of single layer film, or each interfaces of multilayer film in optical sensors leads to constructive and destructive fringes of the optical interference pattern. Nanoporous films with large surface-to-volume ratio are beneficial to improve the sensitivity and lower the limit of detection of the sensors, which is typically used in the form of single layer, double layer or multilayer (usually served as photonic crystal). In this article, we introduce and review the applications of nanoporous films of silicon, anodic aluminum oxide, titanium dioxide and metal-organic framework in optical sensors based on the optical interference. A perspective of developments in this research field is also provided.

Key words: optical sensors, optical interference, nanoporous film, photonic crystal
