Instrument using a highly focused laser to provide an attractive or repulsive force (on the order of piconewtons) to hold and move microscopic dielectric objects similar to tweezers.
The tool used for such operations are known as opticaltweezers.

Like the opticaltweezers, these short pulses can also be used to observe microscopic processes.
3
We use opticaltweezers to trap particles in solution.

He developed opticaltweezers in 1970, while he was a scientist working at Bell Labs.
5
Here we use opticaltweezers to track microtubule polymerization against microfabricated barriers, permitting unprecedented spatial resolution.
6
Our results may also be directly applicable to a few-fermion system prepared in microtraps and opticaltweezers.
7
We have followed individual ribosomes as they translate single messenger RNA hairpins tethered by the ends to opticaltweezers.
8
They held onto their fat granule probe using opticaltweezers, which are basically a nanoscale version of a tractor beam.

In particular, opticaltweezers let scientists study the springiness and bendiness of biological structures, says physicist Michelle Wang of Cornell University.
10
Detecting DNA bridge formation generally involves the use of complex single-molecule techniques (atomic force microscopy, magnetic, or opticaltweezers).
11
Here, by using blinking opticaltweezers, we detect these inertial effects on time scales several orders longer up to a few seconds.
12
Using opticaltweezers, University of Otago physicists led by Niels Kjaergaard are splitting tiny clouds of rubidium atoms and smashing them together.
13
We have developed an opticaltweezers instrument that can independently handle two DNA molecules, which allows the systematic investigation of protein-mediated DNA-DNA interactions.
14
Wang uses opticaltweezers to study the twisting motion of motor proteins, which are structures that move molecules and other objects around the body.
15
The force required to rupture bonds between individual Staphylococcus aureus MSCRAMMs and surfaces coated with extracellular matrix molecules has been quantified by using opticaltweezers.
16
Opticaltweezers allow noninvasive manipulation of subcellular compartments to study their physical interactions and attachments.
