Abstract In recent years, sensing applications have played a very important role in various fields. As a novel natural material, cellulose-based membranes with many merits can be served as all kinds of sensors. This review summarizes the recent progress of cellulose membranes as sensors, mainly focusing on their preparation processes and sensing properties. In addition, the opportunities and challenges of cellulose membrane-based sensors are also prospected. This review provides some references for the design of cellulose membrane materials for sensing applications in the future. Graphic abstract

Introduction Sensors are widely used in various areas of social development and human life, such as industrial production, agricultural planting, environmental detection and disease diagnosis (Ghoneim et al. 2019). According to the changes of environmental factors, sensors can be divided into three categories:

physical sensors that respond to pressure/strain, temperature and humidity; chemical sensors that respond to metal cations, non-metal ions, pH, gas/vapor and toxic organic compounds; and biosensors that respond to biomolecules and pathogens (Dai et al. 2020; Zhang et al. 2020; Fan et al. 2020a, b). At present, although the traditional instrument analysis methods have the merits of sensitivity and professionalism, they still exhibit some drawbacks: expensive instruments, complicated operation steps and professional operators. Therefore, the development of green, convenient, rapidly responding, multifunctional, highly sensitive and selective sensors is urgently needed. Due to their various advantages of portable, realtime detection and flexible, the membrane materials have aroused a widespread interest of researchers. Until now, membrane materials are mainly inorganic matrices (e.g. metal oxides and ceramics) and organic substrates (Lee et al. 2019; Bassyouni et al. 2019; Weishaupt et al. 2020). However, inorganic matrices have the disadvantages of high cost, difficult processing and small market appli
