A Magnetically Driven Amoeba‐Like Nanorobot for Whole‐Process Active Drug Transport
The passive diffusion performance of nanocarriers results in inefficient drug transport across multiple biological barriers and consequently cancer therapy failure.

Carbon sequestration by multiple biological pump pathways in a coastal upwelling biome
Multiple processes transport carbon into the deep ocean as part of the biological carbon pump, leading to long-term carbon sequestration. However, our ability to predict future changes in these processes is hampered by the absence of studies that have ...

The Balance of Fluid and Osmotic Pressures across Active Biological Membranes with Application to the Corneal Endothelium. [PDF]
The movement of fluid and solutes across biological membranes facilitates the transport of nutrients for living organisms and maintains the fluid and osmotic pressures in biological systems. Understanding the pressure balances across membranes is crucial

Biological and Medical Aspects of Active Heal Transport of Bile Acids
The active transport of conjugated bile acids by the ileum is responsible for the enterohepatic circulation of bile acids, a physiological process that ensures an ample supply to the intestine of these key biological surfactants, irrespective of the rate of their biosynthesis from cholesterol.

Optimal transport and control of active drops [PDF]
Significance Transportation, in its broadest sense, is an important task in many fields, including engineering, physics, biology, and economics, and a great deal is known about optimal and efficient strategies to move matter, energy, and information ...

Quantifying biological carbon pump pathways with a data-constrained mechanistic model ensemble approach [PDF]
The ability to constrain the mechanisms that transport organic carbon into the deep ocean is complicated by the multiple physical, chemical, and ecological processes that intersect to create, transform, and transport particles in the ocean. In this paper

Kidney epithelial cells are active mechano-biological fluid pumps
The role of mechanical forces driving kidney epithelial fluid transport and morphogenesis in kidney diseases is unclear. Here, using a microfluidic platform to recapitulate fluid transport activity of kidney cells, we report that renal epithelial cells ...

Transport of complex and active fluids in porous media
Complex and active fluids find broad applications in flows through porous materials. Nontrivial rheology can couple to porous microstructure leading to surprising flow patterns and associated transport properties in geophysical, biological, and ...

Phenomenological model of motility by spatiotemporal modulation of active interactions
Transport at microscopic length scales is essential in biological systems and various technologies, including microfluidics. Recent experiments achieved self-organized transport phenomena in microtubule active matter using light to modulate motor-protein
