Abstract

The ever‐evolving topic of optical micromanipulation has established itself as a discipline over the last three decades, and is of much interest to a wide research community due to constantly emerging new applications across the various key disciplines. Performing optical manipulation using evanescent waves is termed near‐field optical manipulation, which is essentially the manipulation of particles in the non‐diffractive regime. The concept of the breaking of diffraction limit is the spur driving near‐field optics studies, as opposed to all far field optical applications where light cannot be focused to a spot smaller than the diffraction limited value, which is about half the wavelength of light in the medium. The authors present a review of the various near‐field optical manipulation techniques and then report on the observation of erythrocyte pearl chains by a near‐field optical tweezer.
