The flexible manipulation of particles or cells in fluids， particularly the transport of cells or particles to a specified location， has proven to be of vital importance in cell analysis， disease diagnosis， drug delivery， etc. However， the flexibility of contact-free optical capture of cells or particles is clearly insufficient owing to the short operating distance of optical fiber tweezers. Therefore， a novel optical fiber tweezer with a simple structure and controllable long-distance contact-free control of particles is proposed. In this study， a special cone-like flat port fiber probe is fabricated via heating and stretching techniques. A 980 nm laser passing through the fiber probe exerts a large scattering force on the particles， which gradually pushes the particles away from the fiber port. Simultaneously， with the aid of reverse fluid resistance， the output power of the laser light source is adjusted without moving the fiber probe. A polystyrene particle with a diameter of 6 µm in an axial position can be controlled round-trip with a distance of 102.2 µm. The intensity distribution of the optical tweezers is simulated using the finite element method， and the force exerted by the optical tweezers on the particles is analyzed using the Maxwell stress tensor method. The feasibility of the proposed cone-like flat port optical tweezers is verified via both experiments and simulations.
