Abstract
Embodiments generally relate to devices, systems and methods for separating CTCs from blood cells using optical trapping, such as use of optical cogwheel tweezers. Through a pre-filtration process, using optical cogwheel tweezers, desired cells from a cell sample can be filtered from a relatively dilute sample. The filtered sample can then be analyzed by more precise means to determine overall concentrations from the original sample while maintaining cell viability.
