“…The most outstanding feature of the microfluidic system is its ability to analyze and manipulate microliters of fluid in channels with diameters of 10–100 μm [ 41 , 42 ]. A porous structured microfluidic system with small thermal mass, high mass transfer efficiency, high specific surface area, good permeability, low relative density and high specific strength can effectively improve the flux rate and sensitivity of the device [ 43 , 44 , 45 , 46 , 47 , 48 , 49 ]. The diversity of porous materials stems from a wide range of preparation methods [ 50 , 51 , 52 , 53 , 54 ].…”

Microfluidics has recently received more and more attention in applications such as biomedical, chemical and medicine. With the development of microelectronics technology as well as material science in recent years, microfluidic devices have made great progress. Porous structures as a discontinuous medium in which the special flow phenomena of fluids lead to their potential and special applications in microfluidics offer a unique way to develop completely new microfluidic chips. In this article, we firstly introduce the fabrication methods for porous structures of different materials. Then, the physical effects of microfluid flow in porous media and their related physical models are discussed. Finally, the state-of-the-art porous microfluidic chips and their applications in biomedicine are summarized, and we present the current problems and future directions in this field.

The burden of food contamination and food wastage has significantly contributed to the increased prevalence of foodborne disease and food insecurity all over the world. Due to this, there is an urgent need to develop a smarter food traceability system. Recent advancements in biosensors that are easy-to-use, rapid yet selective, sensitive, and cost-effective have shown great promise to meet the critical demand for onsite and immediate diagnosis and treatment of food safety and quality control (i.e. point-of-care technology). This review article focuses on the recent development of different biosensors for food safety and quality monitoring. In general, the application of biosensors in agriculture (i.e. pre-harvest stage) for early detection and routine control of plant infections or stress is discussed. Afterward, a more detailed advancement of biosensors in the past five years within the food supply chain (i.e. post-harvest stage) to detect different types of food contaminants and smart food packaging is highlighted. A section that discusses perspectives for the development of biosensors in the future is also mentioned.

“…Cu NCs could act as biocatalysts owing to their ultra-small size and their catalytic center being a metal core. 32 Self-assembled Cu NSs with a potentially catalytically active center were utilized as catalytic nano-enzymes. Using OPD as a substrate, we investigated the mimic peroxidase catalytic activity of Cu NSs in the presence of H 2 O 2 .…”
