New active filaments mimic biology to transport nano-cargo

Very interesting read. The researchers created a completely artificial microscopic transport system mimicking the human body. With this technology we’re going to be able to address many areas of healthcare as well as some areas of AI.

Inspired by micro-scale motions of nature, a group of researchers at the Indian Institute of Technology Madras and the Institute of Mathematical Sciences, in Chennai, India, has developed a new design for transporting colloidal particles, tiny cargo suspended in substances such as fluids or gels, more rapidly than is currently possible by diffusion.

Fluid friction determines micro-scale inertia in fluid. This means, for instance, blood cells swimming within blood encounter roughly the same amount of drag that a human would experience attempting to swim through molasses.

As the group reports in The Journal of Chemical Physics, from AIP Publishing, they applied and then extended a model of active filaments that includes these frictional hydrodynamic interactions, specifically as they relate to the speed and efficiency analysis of transporting colloidal particles.
