Sensing Forces in the Microworld

چکیده
Holographic optical tweezers (HOT) are a versatile tool allowing for the generation of complex arrays of multiple optical traps which act as force sensors with piconewton resolution. The combination of HOT and stop-flow microfluidics integrated with a fluorescence microscope gives full spatial, chemical and visual control over the microenvironment. This allows us to investigate the dynamic properties of complex biosystems at the microscale, such as crosslinking in biomimetic actin networks.

Invited article: a review of haptic optical tweezers for an interactive microworld exploration.
This paper is the first review of haptic optical tweezers, a new technique which associates force feedback teleoperation with optical tweezers. This technique allows users to explore the microworld by sensing and exerting picoNewton-scale forces with trapped microspheres. Haptic optical tweezers also allow improved dexterity of micromanipulation and micro-assembly. One of the challenges of this...
متن کاملStatus driven teleoperation system: a new paradigm and an application to the microworld
This paper proposes a third generation teleoperation system based on a status driven slave symbolically instructed by the master control panel. Furthering the first generation joint-angle control techniques and second generation coordinate transformation techniques, this system recognizes the target status specified by the operator by extracting the task status from visual sensors. The task env...

متن کاملTouching the microworld with force-feedback optical tweezers.
Optical tweezers are a powerful tool for micromanipulation and measurement of picoNewton sized forces. However, conventional interfaces present difficulties as the user cannot feel the forces involved. We present an interface to optical tweezers, based around a low-cost commercial force feedback device. The different dynamics of the micro-world make intuitive force feedback a challenge. We prop...
