The spike centrifuge is an innovative microfluidic device that harnesses centrifugal force to manipulate and analyze particles, cells, and fluids. Its unique design and versatility have revolutionized various fields of scientific research and industrial applications. This article delves into the fundamental principles, applications, and practical aspects of spike centrifuges, providing a comprehensive guide to their use and benefits.
Spike centrifuges consist of a compact, disk-shaped rotor with a series of spikes protruding from its surface. When the rotor is rotated at high speeds, the centrifugal force generated propels the sample (typically a droplet of fluid) towards the periphery of the disk.
As the droplet encounters the spikes, it experiences a shear force that breaks it into smaller droplets or particles. This process, known as spike-induced droplet fragmentation, enables the precise control of droplet size and均匀性. The fragmented droplets can then be further manipulated, analyzed, or sorted based on their size, density, or other properties.
The spike centrifuge has found widespread applications across several disciplines, including:
