Nanomaterials are at the forefront of the fast-paced development of nanotechnology. These materials are outstanding and indispensable in various human activities as long as their size-dependent characteristics. One of the most promising applications of nanomaterials is biomedical. This work reviews the hybrid quantum dot-metal nanoparticle applications in biomedical. An analytical model for the double quantum dot–metal nanoparticle system is proposed, and the system susceptibility is calculated.

“…Then, only single-dimensional transitions are allowed. The WL-QD transition momentum is then calculated as follows (take the VB WL-QD as an example): μ35=⟨φQDj=3|er→|φwLv⟩,which is written as 12 μ35=⟨ψQDj=3|eρ^ρ|ψwLv⟩AQDz3Awz5∫cos(kzv)cos(kzwvz)dz,where φQDj=3 are the QD states total wavefunctions |3⟩ and φwLv WL VB, φQDj…”

Due to the limited study, this work engineers the parameters controlling the rate of absorbed energy from a double quantum dot (DQD)-metal nanoparticle (MNP) system at plasmonic electromagnetically induced transparency (PEIT) considering the strong coupling between DQD and MNP. The modeling is of the material property for which the energy states and transition momenta are calculated. The analysis considers the orthogonalized plane wave between the wetting layer (WL)-QD transitions. A huge ð10 −5 WÞ total absorption rate ðQ total Þ from the system is attained. This result is higher by four orders and the power applied is less by three orders than that obtained in the literature. Many features are studied. Neglecting the WL, the system spectrum is similar to the left-handed picture of the system with WL. The value of Q depends on the situation of the QD energy states through the variation of the QD size, MNP radius, and distance separating the system. In the DQD-MNP hybrid system, the controlling factor that gives a high Q total in the PEIT case is the DQD combination with a weak probe and enough pump, i.e., the DQD structure works as a whole structure, not as two QDs working separately. Such a structure allows for manipulating the flexibility of carriers between DQD states that are not found in other structures. From the results, one can conclude that DQD behavior under the pump, probe, and single tunneling component produces two transparent windows. Adding a second tunneling component creates four transparency windows depending on the values of these applied parameters.
