Article Correctness Is Author's Responsibility: A remote control for everything small

(Vienna University of Technology) Special light beams can be used to manipulate molecules or small biological particles. However, these optical tweezers only work with objects in empty space. Any disturbing environment would deflect the light waves and destroy the effect. This is a problem, in particular with biological samples. Now, a special method was developed to calculate the perfect wave form to manipulate small particles in the presence of a disordered environment, even if they cannot be touched directly.
