Raman Tweezers Micro Spectroscopy has become an important and versatile technique in recent years. The technique is the amalgamation of optical tweezers and traditional Raman spectroscopy. The combination of these two well established techniques has brought key advantages in the studies of many different physical and biological systems from studying drug distribution in cells to measuring the size of aerosol particles. In this paper we present our Raman Tweezers system and discuss its advantages over conventional Raman systems, also discussed in this section is the parameters which effect collection of Raman scattered light using the ability of the optical tweezers to stack micro spheres. Finally we discuss how to extend further the functionality of the Raman tweezers technique by decoupling the trapping and excitation with the use of a fibre optical light force trap.
