Silica microspheres in liquid crystals offer the possibility of creating every knot conceivable

Knots can now be tied systematically in the microscopic world. A team of scientists led by Uros Tkalec from the Jozef Stefan Institute in Ljubljana (Slovenia), who has been working at the Max Planck Institute for Dynamics and Self-Organization in Gottingen (Germany) since September 2010, has now found a way to create every imaginable knot inside a liquid crystal.
