How advanced optical tweezers revolutionized cell manipulation

Optical tweezers (OTs), also known as optical traps, are highly focused laser beams that can be used to trap and manipulate microscopic objects with a noncontact force. Employed in a wide range of nano and micro-scale operations, ...

A new way to produce pheromones as a crop pest repellent

A team of researchers from Sweden, China and the U.S. has developed a much cheaper way to produce pheromones as a crop pest repellent. In their paper published in the journal Nature Sustainability, the group describes how ...

Physicists develop a perfect light trap

Whether in photosynthesis or in a photovoltaic system: if you want to use light efficiently, you have to absorb it as completely as possible. However, this is difficult if the absorption is to take place in a thin layer of ...

Customized fiber generates Bessel beams

An all fiber-based approach to generating special optical beams, called Bessel beams, could open up new applications in imaging, optical trapping and communications.
