Microfluidic paper-based analysis devices (μPADs) have undergone tremendous development in recent years and now provide a feasible low-cost alternative to traditional laboratory tests for the diagnosis of many common diseases and disorders. As such, they are of great interest and importance in developing regions of the world with a lack of medical resources and associated infrastructures. This review examines the advances made in microfluidic paper-based diagnostic technology in the past five years and describes the application of microfluidic paper-based assays to the detection of many common human diseases using 3 non-invasive samples sources such as saliva, tears and sweat. The review commences by introducing the basic principles of fluid transport in microfluidic paper-based devices. The structures and actuation systems used in common paper-based devices are then introduced and explained. A systematic review of recent proposals for the application of paper-based devices to the diagnosis of common human diseases is then presented. The review concludes with a brief discussion of the challenges facing the microfluidics paper-based diagnosis field in the coming years and the emerging opportunities for future research.

Electrochemical paper based cancer biosensor using iron oxide nanoparticles decorated PEDOT:PSS

In recent years, optical sensing based on nanomaterials has emerged as a prospective strategy for monitoring environmental pollution in water. In this context, carbon nanostructures have received increasing attention due to their unique optoelectronic and physiochemical properties. To this end, nanocarbon such as carbon nanotubes, graphene, and carbon dots have been used to develop proof-of-concept opto-chemical sensors for emerging aquatic contaminants, including pesticides, bacterial pathogens, and pharmaceuticals residues. These optical sensors have attracted significant research interest in nanotechnology, material science, and the detection of aquatic pollutants. However, the practical application for detecting contaminants is still limited because of cost-effectiveness, sensitivities, and selectivity toward the diverse pollutants. This review examines the current trends and challenges in designing and applying carbon nanostructure-based optical sensors for detecting aquatic contaminants. Finally, a critical perspective on the field and future research directions is provided.
