| contents | Here we propose the use of the organic semiconductor polyaniline (PANI) for the preparation of spherical-shaped microparticles to serve as handles in optical tweezers (OT) experiments. The stable trapping and manipulation of PANI beads was demonstrated for the first time, using a Gaussian ($TEM_{00}$) beam optical tweezers. The trap stiffness was characterized for various different parameters such as the bead radius, the laser power and the distance between the bead and the coverslip of the sample chamber, attesting the viability of using such material for optical manipulation. Since the effective optical properties of PANI can be modulated by the synthesis process, new related applications are also proposed. The results of the present work therefore open the door for using semiconductor polymeric materials in OT applications. |
