“…The rapid pace of progress in two dimensional (2D) materials after graphene [1], transition metal di-chalcogenides (TMD's) [2,3] and other 2D materials like hexagonal boron nitride [4], silicene [5], phosphorene [6], tellurene, arsenene etc. [7,8] have attracted great deal of attention because these materials exhibit potential for various applications such as in solar cell, optoelectronic devices, bio-sensing [9][10][11][12][13] etc. In the field of bio-molecular analysis [14], disease diagnosis [15,16] and forensic sciences [17], 2D nano-materials play a very important role because they have required high surface-to-volume ratio [18].…”
