Organ-on-a-chip
A microfluidic cell culture device that simulates the activities, mechanics and physiological response of entire organs or organ systems.
Organ-on-a-chip
An organ-on-a-chip represents a revolutionary convergence of microfluidics and tissue engineering, creating miniature models that replicate key functions of human organs. These sophisticated devices, typically the size of a USB stick, combine living cells with artificial structures to simulate organ functionality in a controlled environment.
