Info in nanotechnology, optical tweezers

In summary, the person is looking for information about optical tweezers, but is unsure about what other forces might exist. They ask for help from others, but are doubtful that anyone will be able to provide it.

i did that earlier... but that is not what i am looking.. some specific info...eg. what forces exist when handling nanoparticles with laser lights... papers i have seen discuss abt only 2 forces.. i doubt that there mite also b other forces.. so issues like these are kinda doubtful for me... so if any1 of u know abt optical tweezers.. or have any gud papers on them.. please let me know.. thanks for helping in clarifyin my own question... lookin forward for furthur help

well there seems to be confusion among people.. sory for that...
I am currently working on Optical Tweezers... My case involves forces experienced by a sphere (of some nanometeres in diameter) in water. I know that optical forces are the major forces, apart from that what all forces does the sphere experience. Also, my past glance at some papers on nanoparticle manipulation says me that capillary,electrostatic,van der waals, gravity and buoyancy forces can exist. I am not sure of these.. and thus i am reerting to you people...
Hope i am somewhat clear now... please let me know for furthur clarifications
Feeling sad that inspite of these many conversation in this thread... there hsnt beeen productive result... sorry if i wasted ur time

thanks a lot for the support u have shown till now

lukin forward to hear from you
have a nice time
thanks once again
 

FAQ: Info in nanotechnology, optical tweezers

What is nanotechnology?

Nanotechnology is a field of science that involves the manipulation and control of matter on a nanoscale, typically at the atomic and molecular level. It involves creating, studying, and using materials and devices with dimensions between 1 and 100 nanometers.

How are optical tweezers used in nanotechnology?

Optical tweezers are a type of microscope that use laser beams to manipulate and move small particles, such as nanoparticles, in a precise manner. In nanotechnology, they are often used to assemble and manipulate structures at the nanoscale, allowing for the creation of new materials and devices with unique properties.

What are the potential applications of nanotechnology?

Nanotechnology has a wide range of potential applications, including in medicine, electronics, energy production, and environmental remediation. Some examples include targeted drug delivery, improved solar cells, and water filtration systems.

Are there any potential risks associated with nanotechnology?

As with any emerging technology, there are potential risks associated with nanotechnology. These include concerns about the environmental and health impacts of nanoparticles, as well as ethical concerns about the potential misuse of nanotechnology. However, extensive research and regulations are in place to address these risks.

How is nanotechnology impacting the future?

Nanotechnology is expected to have a significant impact on many aspects of our lives in the future. It has the potential to revolutionize industries, such as healthcare and energy, and to create new materials and technologies that were previously impossible. It is also expected to have a significant impact on the global economy and job market.
