Bionic forceps for the handling of sensitive tissue

open access: yesCurrent Directions in Biomedical Engineering, 2016
Anatomical forceps are used for the handling of sensitive structures in medicine. Structures which are manipulated with these forceps can get damaged or slip out of the grip of the forceps.

Utilization of Optical Tweezer Nanotechnology in Membrane Interaction Studies

open access: yesApplied Nano, 2022
Optical tweezers have been a fixture of microscopic cell manipulation since the 1990s. Arthur Ashkin’s seminal work has led to the advancement of optical tweezers as an effective tool for assay development in the fields of physics and nanotechnology.

Simulation of superresolution holography for optical tweezers [PDF]

open access: yes, 2008
Optical tweezers manipulate microscopic particles using foci of light beams. Their performance is therefore limited by diffraction. Using computer simulations of a model system, we investigate the application of superresolution holography for two ...

Reconfigurable multi-component micromachines driven by optoelectronic tweezers

open access: yesNature Communications, 2021
There is great interest in the development of micromotors which can convert energy to motion in sub-millimeter dimensions. Micromachines take the micromotor concept a step further, comprising complex systems in which multiple components work in concert ...

Acoustic Tweezers for Particle and Fluid Micromanipulation

open access: yesAnnual Review of Fluid Mechanics, 2020
Acoustic tweezers powerfully enable the contactless collective or selective manipulation of microscopic objects. Trapping is achieved without pretagging, with forces several orders of magnitude larger than optical tweezers at the same input power ...

Linear microrheology with optical tweezers of living cells 'is not an option'! [PDF]

open access: yes, 2015
Optical tweezers have been successfully adopted as exceptionally sensitive transducers for microrheology studies of complex fluids. Despite the general trend, in this article I explain why a similar approach should not be adopted for microrheology ...

Single-Molecule Studies of Protein Folding with Optical Tweezers.

open access: yesAnnual Review of Biochemistry, 2020
Manipulation of individual molecules with optical tweezers provides a powerful means of interrogating the structure and folding of proteins. Mechanical force is not only a relevant quantity in cellular protein folding and function, but also a convenient ...

Three dimensional acoustic tweezers with vortex streaming

open access: yes, 2021
Acoustic tweezers use ultrasound for contact-free manipulation of particles from millimeter to sub-micrometer scale. Particle trapping is usually associated with either radiation forces or acoustic streaming fields. Acoustic tweezers based on single-beam
