**4. Conclusion**

The main concern of this chapter is to deliver a general perception on the generation of plasma inside liquid and its importance in the field of material fabrication. In-Liquid Plasma method offers single-step, rapid and large-scale synthesis of uniform nanomaterials with different shapes, sizes and compositions. Moreover, from the economic point of view, it is a cost-effective approach as it does not require any gas, water cool vacuum chambers and pumping systems. Interaction of various reactive species on the synthesis of pure metal and metal oxide nanoparticles as well as nanocomposites has been discussed in this chapter. Morphological and compositional modification of nanomaterials by controlling the physical (e.g. applied voltage, current, pulse width and discharge duration) and chemical (e.g. solution concentration, pH and surfactant) parameters have also been discussed.
