By determining how much laser power is required to pull the microsphere away from the surface, one can then calculate the amount of force needed to...

New technique reveals subtle force-induced changes in biomolecule's conformation

...ing the brightness of the two dyes, the researchers can determine the motion of the molecule. With the optical trap, a focused laser beam locks onto a microsphere attached to one end of the molecule to be studied. The optical trap can then pull on the molecule like a pair of tweezers. The project is funded by...

Biodegradable microspheres deliver time release vaccines, stimulate different immune response

... a vaccine delivery system that released the vaccine into the system slowly over time. They chose a biodegradable polymer, called polyandydride, in a microsphere formulation. This polymer was already being used as a delivery system for a brain cancer drug designed to inhibit tumor growth. "It's like an Ev...

Gold nanoparticles prove to be hot stuff

...omolecules such as DNA or protein by manipulating a tiny sphere--typically polystyrene--attached to the molecule. The JILA team would like to find new microsphere materials that can be trapped by laser radiation pressure more efficiently, which would enable faster measurements and detection of smaller motions at...

Researchers putting a freeze on oscillator vibrations

...onons -- vibrations that carry energy -- is becoming increasingly important. For their project, Wang and Park purposely manufactured a deformed silica microsphere about 30 microns in diameter, about the size of a human hair. A combination of cryogenic pre-cooling of the sphere to 1.4 Kelvin (minus 457.15 degr...

Researchers measure elusive repulsive force from quantum fluctuations

...ime, Capasso and his colleagues measured what they have deemed a repulsive Casimir. To measure the repulsive force, the team immersed a gold coated microsphere attached to a mechanical cantilever in a liquid (bromobenzene) and measured its deflection as the distance from a nearby silica plate was varied.
