Web2 days ago · Firstly, it can be observed that the radial scattering force is significantly smaller compared to the gradient force, implying that the gradient force plays a predominant role in optical capture. Secondly, there are multiple points in the gradient force curve where the force magnitude is zero, which indicates that particles will be trapped in ... WebAug 17, 2024 · Optical forces arise when objects absorb, refract or scatter light and momentum is transferred. For levels of optical power that do not damage cells, these forces are very small, typically on...
