Tailoring the optical dipole force for use on molecules

(PhysOrg.com) -- "Scientists have been working with dipole fields for quite some time," Peter Barker tells PhysOrg.com. "However, most of the work is focused on very small particles, like atoms, or on larger particles, such ...

Nanotechnology gets a new light touch

(PhysOrg.com) -- Building the super-fast computers of the future has just become much easier thanks to an advance by Australian researchers that lets them grab hold of tiny electronics components and probe their inner structure ...

Bionanomachines: Proteins as resistance fighters

(PhysOrg.com) -- Friction limits the speed and efficiency of macroscopic engines. Is this also true for nanomachines? A Dresden research team used laser tweezers to measure the friction between a single motor protein molecule ...

Using high-precision laser tweezers to juggle cells

Researchers at the University of Gothenburg, Sweden, have developed a new method to study single cells while exposing them to controlled environmental changes. The unique method, where a set of laser tweezers move the cell ...

The Power of Light: Moving Macroscopic Amounts of Matter

(PhysOrg.com) -- Since 1970, scientists have been working with “optical tweezers” - lasers that move microscopic amounts of matter using forces originating from the light matter interaction. Now, for the first time, researchers ...
