In the current study, an analytical model is presented to analyze interaction between a moving 6-Methoxy-8-[[6-Methoxy-8-[[6-Methoxy-2-Methyl-1-(2-Methylpropyl)-3,4-Dihydro-1H-Isoquinolin-7-yl]Oxy]-2-Methyl-1-(2-Methylpropyl)-3,4-Dihydro-1H-Isoquinolin-7-yl]Oxy]-2-Methyl-1-(2-Methylpropyl)-3,4-Dihydro-1H Isoquinolin-7-ol and a two-mode field in the presence of two-photon transitions and in the coupling regime dependent on intensity for human cancer cells, tissues and tumors diagnosis. After identifying the initial condition of the nano molecule and the field, explicit form of state vector of the system is obtained by time evolution operator. In order to study the entanglement between two subsystems of nano molecule and field, the temporal behavior of Von Neumann entropy is evaluated as a measure of degree of entanglement for human cancer cells, tissues and tumors diagnosis.
