Quantum fluctuations can induce a long-range force between macroscopic bodies -- the Casimir effect. In recent years, people have devoted substantial efforts to alter the sign and strength of Casimir forces. The attractive Casimir force is unwelcome for nanodevices and colloids, because it can make nearby parts stick together. Here, by using chiral materials as an intervening ``lubricant'', the authors propose a universal way to achieve repulsive, enhanced, and tunable Casimir forces.
