Mechanism of Ciliary Motion

Mechanism of Ciliary Motion

The ciliary structures were first seen in 1647 by Antonie Leeuwenhoek while observing the protozoans. In lower organisms, these appendages are responsible for cell movement, while in higher organisms, these appendages help in the movement of the extracellular fluids within the body cavities.
The cilia are made up of microtubules in a 9+2 arrangement, with nine microtubule doublet ring bundles, surrounding a pair of central singlet microtubule bundles. The doublet microtubule bundles are...

Linear Momentum in Control Volume

Linear Momentum in Control Volume

Newton's second law is applied to obtain the linear momentum in a control volume in a fluid system. According to this law, the rate of change of linear momentum is equal to the sum of external forces acting on the system. When a control volume matches the fluid system at a specific moment, the forces acting on both are identical. Reynolds transport theorem helps explain this by breaking down the system's linear momentum into two components: the rate of change of linear momentum within...

Area of Science:

Optomechanics
Soft Matter Physics
Nanophotonics

Background:

Optical tweezers utilize light radiation pressure to manipulate microscopic objects.
Light momentum transfer in optical waveguides can induce mechanical forces.
Conventional materials' rigidity typically makes these forces negligible.

Purpose of the Study:

To demonstrate significant mechanical deformation in soft photopolymer optical waveguides driven by light momentum.
To explore the potential of light-induced movement in microscale structures.
To investigate novel applications in micro-actuation.

Main Methods:

Fabrication of micron-scale curved nanowire waveguides using two-photon polymerization direct laser writing.
Guiding light through the soft photopolymer waveguides.
Observation and analysis of waveguide deformation and movement.

Main Results:

Soft photopolymer waveguides exhibited large-scale mechanical movements when guiding light.
Observed deformations were driven by the momentum of photons.
An analytical optomechanical model accurately predicted the shape deformations and their power dependence.

Conclusions:

Soft optical waveguides can undergo substantial light-driven deformation.
This phenomenon enables the development of light-driven micro-actuators.
Findings offer new avenues for photonic and microelectromechanical systems.
