Abstract
Paper-based analytical devices (PADs), including lateral flow assays (LFAs), dipstick assays and microfluidic PADs (μPADs), have a great impact on the healthcare realm and environmental monitoring. This is especially evident in developing countries because PADs-based point-of-care testing (POCT) enables to rapidly determine various (bio)chemical analytes in a miniaturized, cost-effective and user-friendly manner. Low sensitivity and poor specificity are the main bottlenecks associated with PADs, which limit the entry of PADs into the real-life applications. The application of nanomaterials in PADs is showing great improvement in their detection performance in terms of sensitivity, selectivity and accuracy since the nanomaterials have unique physicochemical properties. In this review, the research progress on the nanomaterial-based PADs is summarized by highlighting representative recent publications. We mainly focus on the detection principles, the sensing mechanisms of how they work and applications in disease diagnosis, environmental monitoring and food safety management. In addition, the limitations and challenges associated with the development of nanomaterial-based PADs are discussed, and further directions in this research field are proposed.

Abstract
Nowadays, food safety has become a major concern for the sustainability of global public health. Through the production and distribution steps, food can be contaminated by either chemical hazards or pathogens, and the determination of these plays a critical role in the processes of ensuring food safety. Therefore, the development of analytical tools that can provide rapid screening of these hazards is highly necessary. Microfluidic paper-based analytical devices (µPADs) have advanced significantly in recent years as they are rapid and low-cost analytical screening tools for testing contaminated food products. This review focuses on recent developments of µPADs for various applications in the food safety field. A description of the fabrication of selected papers is briefly discussed, and evaluation of the μPADs' performance with regard to their precision and accuracy as well as their limits of detection is critically assessed. The advantages and disadvantages of these devices are highlighted.

Abstract
Lateral flow assays, as a low-cost, simple, portable and disposable product of vitro diagnostic, are being widely used for point-of-care testing. However, the poor sensitivity of LFAs is the main challenge for commercialization. In order to enhance the sensitivity of LFAs, cellulose nanofibers (CNFs) have been integrated into LFAs to enhance the sensitivity of protein LFAs. A simple method is also presented to modify the properties of paper substrate by incorporating CNFs into a nitrocellulose membrane to enhance the sensitivity of nucleic acid LFAs. This method changes the pore size, porosity, surface groups and surface area of paper substrate and then increases the adsorption ability of biomolecules on paper substrate. The results indicate that the sensitivity of nucleic acid LFAs in Staphylococcus aureus testing achieves a 20-fold enhancement. Hence, we anticipate that this simple method has the potential for other paper-based devices to improve the performance.
