Summary: This article analyzes the impact of copper and diamond nanoparticles on the peristaltic pumping of couple stress nanofluid in a vertical microchannel, regulated by the electro-magneto-hydrodynamic mechanism. The study considers thermal radiation, convective and slip boundary conditions, and examines the effects of different shapes of nanoparticles on shear stress, velocity, temperature, heat transfer rate, and entropy generation. The results show that the couple stress parameter affects the velocity and pressure gradient of the nanofluid, while the shape of nanoparticles and external factors such as magnetic field strength and thermal radiation have varying effects on the nanofluid properties.

Summary: Inspired by nature, nanomotors have been developed that have great potential in microfluidics and biomedical applications. The rotary nanomotor, made up of carbon nanotubes (CNTs) and a circular single-stranded DNA (ssDNA), can be controlled by selectively manipulating ion transport through charged nanopores. The rotation of the nanomotor is driven by the electroosmotic flow (EOF) generated by the oppositely charged dual nanopores, resulting in promising opportunities for precise control of nanomotors.

Summary: This study focuses on the fluid flow and heat transfer characteristics of 10 W40-based titanium dioxide nanofluid subject to electroosmotic forces and peristaltic propulsion in a curved microchannel. The unique aspect of this study is the inclusion of variable thermophoretic and diffusion parameters in the modified Buongiorno model. The results indicate that maintaining a larger temperature difference strengthens buoyancy forces and facilitates fluid motion, but also leads to a decrease in the Nusselt number. It is also found that the temperature of the nanofluid decreases for a larger curvature parameter, corresponding to a less curved channel. Additionally, the electroosmotic flow parameters have a progressive impact on velocity and convective heat transfer.

Summary: Lubricant-impregnated surfaces (LIS) are efficient liquid-repellent surfaces, but their lubricant layer is susceptible to depletion upon exposure to degrading stimuli. This limits the long-term stability and scalability of LIS. In this work, we developed Lubricated Bicontinuous porous Composites (LuBiCs) by infusing a silicone oil lubricant into a bicontinuous porous composite matrix. LuBiCs can replenish the lubricant via capillary action, allowing them to retain liquid-repellent function even after exposure to degrading stimuli. The large-scale LuBiC roof demonstrated slippery behavior after more than 9 months of outdoor exposure.

Summary: Gliomas are primary brain tumors with poor prognosis and high mortality rate. Current diagnostic and monitoring options mainly rely on imaging techniques, which have limitations in providing comprehensive information. Liquid biopsy is a promising alternative for monitoring glioma. Biosensor-based diagnostic and monitoring technology has advantages such as high sensitivity and specificity, high-throughput analysis, and minimally invasive nature. In this review, the authors focused on glioma and summarized the diagnostic and prognostic biomarkers associated with glioma. The review also discussed biosensor approaches for detecting glioma biomarkers and suggested future research directions to improve the integration of biosensors with microfluidic systems for clinical applications.
