Introduction: For first time at 2003, researchers realized that plasmonic could be amplified using stimulated emission, which this concept has caused emerging "Plasmonic Lasers" or "Spasers" (Surface Plasmon Amplification by Stimulated Emission of Radiation). Spasers are nanoscale and subwavelength lasers investigated and used in various fields such as medical. Detect and therapy of cancer and drug delivery are some of their applications in medical. To detect tumors from healthy cells, cancer cells are realized using spaser Nano laser even in deep tissues. In one method, graphene and nanotubes can be pushed to cancer cells and destroy them with laser radiation, or aluminum nanoparticles due to their properties would be used in this way. Spasers have been used as optical probes, to attach CTCs and make them to small pieces. Spasers are introduced in drug delivery in skin field, too, in which method the drug delivery the disadvantages of usual methods are not seen.
Research method: This article is presented based on investigations and studies which are done in mediclal field before, to show plasmonic lasers applications.
Findings: Based on unique properties of plasmonic and materials such as carbon nanotubes, Nano-shells and so on in nanotechnology, integrating lasers and such materials we can reach to significant results and findings in medical field.
Conclusion: Technology goes on and affect all sciences such as medicine. By integrating lasers and palsmonics, new useful and significant finding could be achieved without having usual and common disadvantages of conventional methods. This method can be used in diagnose and therapy of cancer and drug delivery, that are discussed briefly here.
